Answer:

4

Step-by-step explanation:

to find the x intercept of a line in standard form we can simply set y as 0 and find x

4x - 7(0) = 16

4x = 16

x = 4

the answer is 4

The linear equation for the graph in terms of x is given by: y = -0.5x - 3.

A linear function is modeled by:

y = mx + b

In which:

Looking at the graph, when x = 0, y = -3, hence the y-intercept is of b = -3. The graph also passes through point (2,-4), hence the slope is given by:

m = (-4 - (-3))/(2 - 0) = -1/2 = -0.5.

Hence the equation is:

y = -0.5x - 3.

Answer:

a)  u - v

b)  2v - 2

c)  3u + 3

d)  ¹/₂

Step-by-step explanation:

Given:

 [tex]u=\log_{10}3[/tex]

 [tex]v=\log_{10}5[/tex]

Part (a)

Rewrite 0.6 as a fraction:

[tex]\implies \log_{10}(0.6)=\log_{10}\left(\dfrac{3}{5}\right)[/tex]

[tex]\textsf{Apply the quotient log law}: \quad \log_a\frac{x}{y}=\log_ax - \log_ay:[/tex]

[tex]\implies \log_{10}\left(\dfrac{3}{5}\right)=\log_{10}3-\log_{10}5[/tex]

Substitute the values of u and v:

[tex]\implies \log_{10}3-\log_{10}5=u-v[/tex]

Part (b)

Rewrite 0.25 as 25/100:

[tex]\implies \log_{10}(0.25)=\log_{10}\left(\dfrac{25}{100}\right)[/tex]

[tex]\textsf{Apply the quotient log law}: \quad \log_a\frac{x}{y}=\log_ax - \log_ay[/tex]

[tex]\implies \log_{10}\left(\dfrac{25}{100}\right)=\log_{10}(25)-\log_{10}(100)[/tex]

Rewrite 25 as 5² and 100 as 10²:

[tex]\implies \log_{10}(25)-\log_{10}(100)=\log_{10}(5^2)-\log_{10}(10^2)[/tex]

[tex]\textsf{Appy the Power log law}: \quad \log_ax^n=n\log_ax[/tex]

[tex]\implies \log_{10}(5^2)-\log_{10}(10^2)=2\log_{10}5-2\log_{10}10[/tex]

[tex]\textsf{Apply the log law}: \quad \log_aa=1[/tex]

[tex]\implies 2\log_{10}5-2\log_{10}10=2\log_{10}5-2(1)[/tex]

Substitute the value of v:

[tex]\implies 2\log_{10}5-2(1)=2v-2[/tex]

Part (c)

Rewrite 27000 as 30³:

[tex]\implies \log_{10}(27000)=\log_{10}(30^3)[/tex]

[tex]\textsf{Appy the Power log law}: \quad \log_ax^n=n\log_ax[/tex]

[tex]\implies \log_{10}(30^3)=3\log_{10}(30)[/tex]

[tex]\textsf{Apply the log product law}: \quad \log_axy=\log_ax + \log_ay[/tex]

[tex]\implies 3\log_{10}(30)=3\log_{10}(3)+3\log_{10}(10)[/tex]

[tex]\textsf{Apply the log law}: \quad \log_aa=1[/tex]

[tex]\implies 3\log_{10}(3)+3\log_{10}(10)=3\log_{10}(3)+3(1)[/tex]

Substitute the value of u:

[tex]\implies 3\log_{10}(3)+3(1)=3u+3[/tex]

Part (d)

Rewrite √10 as [tex]10^{\frac{1}{2}}[/tex] :

[tex]\implies \log_{10}(\sqrt{10})=\log_{10}(10^{\frac{1}{2}})[/tex]

[tex]\textsf{Appy the Power log law}: \quad \log_ax^n=n\log_ax[/tex]

[tex]\implies \log_{10}(10^{\frac{1}{2}})=\dfrac{1}{2}\log_{10}(10)[/tex]

[tex]\textsf{Apply the log law}: \quad \log_aa=1[/tex]

[tex]\implies \dfrac{1}{2}\log_{10}(10)=\dfrac{1}{2}(1)=\dfrac{1}{2}[/tex]

Answer:

[tex]f(x)=2(2)^{0.5x}-3[/tex]

Step-by-step explanation:

Parent function:

[tex]g(x)=2^x[/tex]

Properties of the given parent function:

Given form of function f(x):

[tex]f(x)=a(b)^{kx}+c[/tex]

If the parent function is  [tex]g(x)=2^x[/tex]  then  b = 2:

[tex]\implies f(x)=a(2)^{kx}+c[/tex]

From inspection of the graphed function f(x):

Therefore, the y-intercept has shifted 2 units down, yet the asymptote has shifted 3 units down.  This implies that there has been a vertical shift of 3 units down and a vertical stretch.

The vertical shift is denoted by the variable "c" so c = -3:

[tex]\implies f(x)=a(2)^{kx}-3[/tex]

The vertical stretch is denoted by the variable "a".  To find value of a, substitute the point of the y-intercept into the equation:

[tex]\begin{aligned}f(0) & = -1\\\implies a(2)^{k \times 0}-3 & =-1\\a-3 & = -1\\a-3+3 & = -1+3\\a & = 2\end{aligned}[/tex]

Therefore, as a = 2:

[tex]\implies f(x)=2(2)^{kx}-3[/tex]

From inspection of the given graph, the curve passes through point (4, 5).  Substitute this point into the equation to find the value of k:

[tex]\begin{aligned}f(4) & = 5\\\implies 2(2)^{4k}-3 & =5\\2(2)^{4k}& =8\\(2)^{4k}& =4\\(2)^{4k}& =2^2\\4k & = 2\\k & = 0.5\end{aligned}[/tex]

Therefore, the equation of the function f(x) is:

[tex]\implies f(x)=2(2)^{0.5x}-3[/tex]

Answer:

E) 200

Step-by-step explanation:

Let the length of the side after cutting the corners =x cm

Length of the side before cutting the corners = x + 4 cm

Area of square before cutting =  (x + 4)² square cm

Area of that square that was cut  = 2*2 = 4 cm²

Area of 4 squares cut from all 4 corners = 4 * 4 = 16 cm²

Area of internal surface area = 180 square cm

                       (x + 4)² -  4*4        = 180

                   x² + 2*4*x + 4² - 16 = 180

 {expand using the identity  (a + b)² = a² + 2ab + b²) }

                     x²  + 8x + 16 -16   = 180

                        x² + 8x  - 180    = 0

                  x² + 18x - 10x - 180 = 0

               x( x + 18) - 10(x + 18) = 0

                         (x + 18) (x - 10) = 0

  x - 10 = 0   {Ignore x +18 = 0}

         x = 10

           length =  x = 10 cm

          breadth = x = 10 cm

         height  = 2 cm

Volume of open box = length * breadth * height

                                  = 10 * 10 * 2

since a² + b² = c²

we can find b by pythagorean theorem.

sqrt(13² - 5²) = b

hence,

b = 12

Answer:   12

Step-by-step explanation:

To find a length of a right triangle, we can use Pythagorean theory:

            leg² + leg² = hypotenuse²              

                  5² + b² = 13²

                 25 + b² = 169

                          b² = 144

                            b = [tex]\sqrt{144}[/tex]

                             b = 12

Answer:

500 is your answer.

Step-by-step explanation:

First solve the length of side BC, CD, EF and FA   Since BC = CD = sqrt( 10^2 + 10^2) BC = CD = 14.1421  

FA = EF = sqrt(10^2 + 20^2) = 23.3607  

So the perimeter = 10 + 10 + 14.1421 + 14.1421 + 23.3607 = 93

The area is made up be triangle FAE, rectangle ABDE and triangle BCD

A = 0.5(20)(20) + (10)(20) + 0.5(20)(10)

Answer:

Step-by-step explanation:

There are two different relations here that can be used to write equations for the value of x:

Using the angle relation, we have ...

  ∠CMA ≅ ∠BMA

  (9x)° = 90°

  x = 90/9 = 10

Using the found value of x in the expressions for the segment lengths, we find ...

  MB = 2x -4 = 2(10) -4 = 16

  CM = x +6 = 10 +6 = 16 . . . . . . . congruent to MB, as it should be

  CB = CM +MB = 16 +16 = 32

The standard form of the equation of the parabola is y + 3 = (1/3) · (x - 3)² and The factored form of the equation of the parabola is y = (1/3) · x · (x - 6).

Mathematically speaking, parabolae are defined by second order polynomials. The standard form of the equation of the parabola is defined by:

y - k = C · (x - h)²     (1)

Where C is the vertex constant.

And the factored form has this form:

y = k · (x - r₁) · (x - r₂)     (2)

First, we determine the standard form of the equation of the parabola: (h, k) = (3, - 3) and (x, y) = (0, 0)

0 - (- 3) = C · (0 - 3)²

3 = 9 · C

C = 1/3

Then, the standard form of the equation of the parabola is y + 3 = (1/3) · (x - 3)². Now we proceed to determine the factored form of the parabola: (r₁ = 0, r₂ = 6), (h, k) = (3, - 3)

- 3 = k · (3 - 0) · (3 - 6)

- 3 = k · 3 · (- 3)

- 3 = - 9 · k

k = 1/3

The factored form of the equation of the parabola is y = (1/3) · x · (x - 6).

This lane symbol is used for marking the beginning and ending of a left turn to the drivers.

What are lane symbols?

A permitted lane usage is denoted by a lane symbol. For example, a lane marked with a diamond is one that is designated for high-occupancy cars.  A lane symbol of a bicycle marks that the lane is designated for cyclists. At crossings, arrows indicate movements that are necessary or allowed. The user of the roadway must yield when there is a row of solid triangles. Likewise, two large curved arrows facing each other on a lane in the middle of a two way road with dashed lines on either sides indicate the beginning and ending of a left turn.

A Lane symbol or marking are also utilized to warn drivers of potentially dangerous situations that may be coming up. For instance, a triangle with no filling indicates a yield ahead. A speed hump is indicated by a succession of lines across a lane that get bigger and wider.

Answer:

Step-by-step explanation:

The surface area of a square pyramid is 1/2 the product of its base perimeter & slant height.

SA = area of base + 1/2 (perimeter of base * slant height)

So, we can substitute 12 and 10 into this equation.

The area of the base is 12*12 (144). The perimeter of the base is 48mm.

144 + 1/2(48*10) = Surface Area.

144 + 240 = Surface Area.

384mm = Surface Area.

Step-by-step explanation:

every hours of training has mapped to monthly pays and each element in hour of training has mapped to unique element in monthly pay.

1. x = a

2. y = b

3. A vertical line has an undefined slope.

4. rise/run or Change in y/change in x (m) = y2 - y1 / x2 - x1

5. Rewrite the equation in slope-intercept form to determine the y-intercept.

In slope-intercept form, the equation of a line in slope-intercept form is, y = mx + b, where m is the slope and the y-intercept = b.

1. The slope of a vertical line is undefined, therefore, the equation for a vertical line is given as: x = a, where a is the value of the x-intercept.

A vertical line that contains (a, b) will have the equation, x = a.

2. The slope of a horizontal line is 0, therefore, the equation of the horizontal line is, y = b, where b is the y-intercept.

A horizontal line that contains (a, b) will therefore have the equation, y = b.

3. A vertical line has an undefined slope.

4. For example, if we have the two points (3, 3) and (0, 5), two methods to find the slope are:

rise/run

or

Change in y/change in x (m) = y2 - y1 / x2 - x1 = 5 - 3 / 0 - 3 = 2/-3 = -2/3.

5. If we have an equation in point-slope form, for example, y - 3 = 2(x - 4), to find the coordinates of its y-intercept, rewrite the equation in slope-intercept form to determine the y-intercept:

y - 3 = 2x - 8

y = 2x - 8 + 3

y = 2x - 5

The y-intercept is -5, thus, the coordinates would be: (0, -5).
