How can I find the area of this figure?​

Answer:

All are functions but the 1st one

Step-by-step explanation:

generally, if you have an equation that will repeat x values, it's not a function. The first one has an infinite number of x values

Answer:

A=2 B=1

Step-by-step explanation:

B is distributive because you have to foil the x out of the parenthesis

A is  because when three or more numbers are added (or multiplied), the sum (or the product) is the same regardless of the grouping of the addends.

Answer:

Step-by-step explanation:

Opposite angles are non-adjacent angles formed by two intersecting lines. Opposite angles are congruent (equal in measure).

3x = 2x + 16

x = 16

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

check

3 * 16 = 2 * 16 + 16

48 = 48

the answer is good

Answer:

x=16

Step-by-step explanation:

Since both angles are vertically opposite, there fore they equal each other.

2x + 16 = 3x

Subtract 3x from both sides

2x - 3x + 16 = 3x - 3x

-x + 16 = 0

-x = 0-16

-x = -16 (Multiply both sides by -1)

x = 16

---------

3x 16 = 48

2*16 + 16 = 48

Answer:

no solution

Step-by-step explanation:

x+2=x+8

Subtract x from each side

x+2-x = x+8-x

2 = 8

This is never true so there is no solution

Answer:

x+2=x+8

x+2-2=x+8-2

x=x+6

x-x=x+6-x

0=6

Step-by-step explanation:

By looking at the formula that the rule is the coefficient of x times z to the power plus 2

so we can write the following geometric sequence

The given function for the height of the firework is a quadratic function

1. Time at which the firework reaches the maximum height is 1 seconds

2. The maximum height of the firework, is 25 yards

3. Time after which the firework will fall to the ground is (1 + √5) seconds

Reason:

The given function that represents the height of the fireworks with time is

presented as follows;

h(t) = -5·t² + 10·t + 20

1. The time at which the firework reaches its maximum height is given by

the maximum point of the given function as follows;

The x-value of the maximum point of a quadratic function is [tex]x = \dfrac{b}{2 \cdot a}[/tex]

Where;

a, and b, are the coefficient of x² and x, in the general form of a quadratic function f(x) = a·x² + b·x + c

By comparison, we have;

[tex]t = -\dfrac{10}{2 \times (-5)} = 1[/tex]

2. The maximum height is given by plugging in the value of t, at the maximum point into the given function as follows;

h(1) = -5×1² + 10×1 + 20 = 25

3 The time at which the firework will fall to the ground, is given by the zero of the function as follows;

When the firework falls to the ground, h(t) = 0 =  -5·t² + 10·t + 20

Dividing both sides by (-5) gives;

[tex]\dfrac{0}{-5} = \dfrac{ -5 \cdot t^2 + 10 \cdot t + 20}{-5} = t^2 - 2 \cdot t - 4[/tex]

t² - 2·t - 4 = 0

By the quadratic formula [tex]x = \dfrac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex], we get;

[tex]t = \dfrac{2\pm \sqrt{(-2)^{2}-4\times 1\times (-4)}}{2\times 1} = \dfrac{2\pm \sqrt{20}}{2\times 1} = \dfrac{2\pm 2 \times \sqrt{5}}{2\times 1} = 1 \pm \sqrt{5}[/tex]

Answer:

(x - 2) • (x - 4) • (x - 8)

Step-by-step explanation:

The first term is,  x2  its coefficient is  1 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  +8  

Step-1 : Multiply the coefficient of the first term by the constant   1 • 8 = 8  

Step-2 : Find two factors of  8  whose sum equals the coefficient of the middle term, which is   -6 .

     -8    +    -1    =    -9  

     -4    +    -2    =    -6    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -4  and  -2  

                    x2 - 4x - 2x - 8

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-4)

             Add up the last 2 terms, pulling out common factors :

                   2 • (x-4)

Step-5 : Add up the four terms of step 4 :

                   (x-2)  •  (x-4)

            Which is the desired factorization

Step-by-step explanation:

50-7=43

43×18.94=814.42

100-15=85

100%=18.94

what about 85%

85×18.94=1609.9÷100=16.099

16.099×7=112.693

814.42+112.693= 927.113

Dilating a trapezoid involves changing its size.

The measure of side OL is 8

The given parameters are:

[tex]\mathbf{O'L' = 6}[/tex]

[tex]\mathbf{k = \frac 34}[/tex]

Side length O'L' is calculated using:

[tex]\mathbf{O'L' = OL \times k}[/tex]

Make OL the subject

[tex]\mathbf{OL = \frac{O'L'}{k}}[/tex]

So, we have:

[tex]\mathbf{OL = \frac{6}{3/4}}[/tex]

[tex]\mathbf{OL = 8}[/tex]

Hence, the measure of side OL is 8

Answer:

y = 90

x = 64

Step-by-step explanation:

y is 90 because of right angle

if add 26 + 90 = 116 -> 180 (angle of straight line) - 116 = 64 which is angle of angle to left of y and therefore x bc opposite angles equal each other

or even if you saw the line that includes x, 26, and y, x is still 64

also, the other angle that is blank should be 26+y (if our calculations are correct) so it would be 116 -> and if we add up everything we should get 360 so, x/64 + 26 + y/90 + blank angle/64 + 116 = 360 -> all correct!
