What is the area of the triangle shown below?

(please help, im trying to bring my grades up)​

Answer:

Answer: {-5, 5}. Product is -25, which is the minimum.

Step-by-step explanation:

let a, b denote the two numbers. We know that b-a=10.

We are looking for a minimum over the product a*b.

One can minimize this using derivatives. In case you have not yet had derivatives, you can also use the vertex of a parabola (since the above is a quadratic form):

The minimum is at the vertex a=-5 and so b=5

Their distance is 10, and their product attains the minimum value of all possiblities -25.                                                                                                          

Answer:

Step-by-step explanation:

let the numbers be x and y,let y>x

y-x=10

y=x+10

product P=xy=x(x+10)=x²+10x

[tex]\frac{dP}{dx} =2x+10\\\frac{dP}{dx} =0,gives\\2x+10=0\\2x=-10\\x=-5\\\frac{d^2P}{dx^2} =2>0 ~at~x=-5\\[/tex]

∴P is minimum at x=-5

y=x+10=-5+10=5

numbers are -5,5

Answer:

Step-by-step explanation: Let the total no of cars in the collection be X

Number of black cars = (1/4)X

Number of red cars = (5/8)X

Number of white cars= 7

Summation of all the cars,

(1/4)X + (5/8)X + 7 = X

X= 56

Therefore,

Number of black cars = (1/4) of 56 = 14

Number of red cars = (5/8) of 56 = 35

Number of white cars = 7

Answer:

The second space (13 feet wide & 15 feet long) is the larger space.

Step-by-step explanation:

According to the question,

Thus, The Area Of Rectangle = Length x Width ⇒ 12 × 16 ⇔ 192 Feet² .

Thus, The Area Of Rectangle = Length x Width ⇒ 13 × 15 ⇔ 195 Feet² . Hence it is Clearly Shown here the The second space (13 feet wide & 15 feet long) is the larger space .

Answer:

56

Step-by-step explanation:

To find the "consequent," write out and solve an equation of ratios:

  3         x

------- = ------

  8         21

Through cross-multiplication, this yields  8x = 63, so that x must be x = 63/8.

Alternatively, solve this modified version of the original equation for x:

  3         21

------- = ------

  8          x

Then 3x = 8(21), or x = 8(7), or x = 56.

Note that 21 and 56 are in the ratio 3:8

Answer:  3.9  (choice A)

==============================================

Work Shown:

Apply the pythagorean theorem to get

a^2+b^2 = c^2

1^2+b^2 = 4^2

1+b^2 = 16

b^2 = 16-1

b^2 = 15

b = sqrt(15)

b = 3.87298

b = 3.9

Answer:

a) 60, because in every triangle, the angles always add up to 180. there are three angles in a triangle, and you k is two add to 120, so of you and 60 to 120 you get 180

Answer:

x=58 degree

Step-by-step explanation:

angle AGF +32 =90 degree (being perpendicular)

angle AGF =90-32

angle AGF =58 degree

angle x =angle AGF (being vertically opposite angles)

x=58 degree

Answer: It is asking for the answer to angle x, which is 68 degrees

==========================================================

Explanation:

The x intercepts (aka roots) are where the graph crosses or touches the x axis. These locations directly correspond to help set up the factors.

The root x = -6 shows that x+6 is a factor.

Effectively, we add 6 to both sides so that we go from x = -6 to x+6 = 0.

Answer:

Top row, third one from left to right

Step-by-step explanation:

Use test points:

when x = 0 , y = 2(0) - 4 = 0 - 4 = -4

(0, -4)

when y = 0, 0 = 2x - 4, 4 = 2x, 2 = x

(2, 0)

Top row, third one from left to right

answer is :59/3-2x^10/3

Step-by-step explanation:

Answer:

Step-by-step explanation:

since there is no table included with the question I'm concluding that you need to find values of y using values of x, simply substitute the x values in the equation and you'll get the y value like this

if x = 1 y = 4

Answer:

x - 0 1 2 3 4 5

y - 3 4 5 6 7 8

It is very simple, all you have to do is add three to x every time, for example if x is 153, y will be 156. 3 should be the beginning, the y intercept in graphs, and the beginning means x should be 0.

Answer:

(5, 0)

Step-by-step explanation:

Se the equations equal

x² - 2x - 15 = 8x - 40

Subtract 8x from both sides

x² - 10x - 15 = -40

add 40 to both sides

x² - 10x + 25 = 0

Factor

(x - 5)(x - 5) = 0

x = 5

---------------

plug in x = 5 into

y = 8x - 40

y = 8(5)- 40

y = 0

-----------------

Solution

(5, 0)

[tex](8x^3)^ \frac{2}{3} \sqrt{75x^3} + 2^3 \sqrt{ 3x^7} =28x^3\sqrt{3x}[/tex]

Step-by-step explanation:

The question is poorly formatted. The original question is:

[tex](8x^3)^ \frac{2}{3} \sqrt{75x^3} + 2^3 \sqrt{ 3x^7[/tex]

We have:

[tex](8x^3)^ \frac{2}{3} \sqrt{75x^3} + 2^3 \sqrt{ 3x^7[/tex]

Open bracket

[tex](8x^3)^ \frac{2}{3} \sqrt{75x^3} + 2^3 \sqrt{ 3x^7} =(8^ \frac{2}{3} *x^{3* \frac{2}{3}}) \sqrt{75x^3} + 2^3 \sqrt{ 3x^7}[/tex]

[tex](8x^3)^ \frac{2}{3} \sqrt{75x^3} + 2^3 \sqrt{ 3x^7} =(8^ \frac{2}{3} *x^2) \sqrt{75x^3} + 2^3 \sqrt{ 3x^7}[/tex]

Express 8 as 2^3

[tex](8x^3)^ \frac{2}{3} \sqrt{75x^3} + 2^3 \sqrt{ 3x^7} =(2^{3* \frac{2}{3}} *x^2) \sqrt{75x^3} + 2^3 \sqrt{ 3x^7}[/tex]

[tex](8x^3)^ \frac{2}{3} \sqrt{75x^3} + 2^3 \sqrt{ 3x^7} =(2^2 *x^2) \sqrt{75x^3} + 2^3 \sqrt{ 3x^7}[/tex]

[tex](8x^3)^ \frac{2}{3} \sqrt{75x^3} + 2^3 \sqrt{ 3x^7} =4x^2 \sqrt{75x^3} + 2^3 \sqrt{ 3x^7}[/tex]

Express 2^3 as 8

[tex](8x^3)^ \frac{2}{3} \sqrt{75x^3} + 2^3 \sqrt{ 3x^7}=4x^2 \sqrt{75x^3} + 8\sqrt{ 3x^7}[/tex]

Expand each exponent

[tex](8x^3)^ \frac{2}{3} \sqrt{75x^3} + 2^3 \sqrt{ 3x^7}=4x^2 \sqrt{25x^2 *3x} + 8\sqrt{ 3x * x^6}[/tex]

Split

[tex](8x^3)^ \frac{2}{3} \sqrt{75x^3} + 2^3 \sqrt{ 3x^7}=4x^2 \sqrt{25x^2} *\sqrt{3x} + 8\sqrt{3x} * \sqrt{x^6}[/tex]

[tex](8x^3)^ \frac{2}{3} \sqrt{75x^3} + 2^3 \sqrt{ 3x^7} =4x^2 *5x *\sqrt{3x} + 8\sqrt{3x} * x^3[/tex]

Factorize

[tex](8x^3)^ \frac{2}{3} \sqrt{75x^3} + 2^3 \sqrt{ 3x^7} =28x^3\sqrt{3x}[/tex]

Answer:

x = -1

Step-by-step explanation:

AB + BC = AC = 28

the way from A to C goes through B.

so, the total way of A to C is the sum of the way from A to B and then from B to C.

=>

(5x + 10) + (2x + 25) = 28

7x + 35 = 28

7x = -7

x = -1

Answer:

x = -1

Step-by-step explanation:

5x + 2x + 10 + 25 = 28

7x + 35 = 28

7x = -7

x = -1

Answer:

Volume of cylinder B = 720 cm³

Step-by-step explanation:

Given:

A and B are similar cylinder

Height of cylinder B = 10 cm

Height of cylinder A = 5 cm

Area of the cross section for cylinder A = 18 cm²

Find:

Volume of cylinder B

Computation:

Area of the cross section for cylinder B = a

So,

(10/5)² = (a/18)

4 = a/18

Area of the cross section for cylinder B = 72 cm²

Volume of cylinder B = Area of the cross section for cylinder B x Height of cylinder B

Volume of cylinder B = 72 x 10

Volume of cylinder B = 720 cm³
