Area of a trapezoid is (base of the top + base fo the bottom)/2 all multiplied by the height(8+6/2)4= (14/2)4=7 x 4=28
So you can do it in the future

the axis of symmetry of a quadratic equation is x = –3. if one of the zeroes of the equation is 4, what is the other zero?

FinnZ [79.3K]

ANSWER

The other zero is

$x = - 10$

EXPLANATION

The axis of symmetry serves as the midpoint of the two zeroes.

We were given that the axis of symmetry of the quadratic equation is
$x = - 3$

We were also given that, one of the zeroes of the quadratic equation is
$x = 4$

Let the other zero of the quadratic equation be
$x = p$

,then, we apply the midpoint formula to find the value of
$p$

Since it is the x-values of the intercepts that gives the solution, we use only the x-value part of the midpoint formula which is given by,

$\frac{x_1 + x_2}{2} = axis \: of \: symmetry$

We substitute to obtain,

$\frac{p + 4}{2} = - 3$

We multiply through by 2 to get,

$p + 4 = - 6$

This implies that,

$p = - 6 - 4$

$p = - 10$

Answer:

$\sqrt{74}$ , or approximately 8.6

Step-by-step explanation:

By creating a right triangle as shown, we see that the given line is the hypotenuse of a right triangle with legs of lengths 5 and 7. By the Pythagorean Theorem, the length of the line is $\sqrt{5^2+7^2}=\sqrt{74}$ .

(HELP ME PLEASE) In a triangle that two of its sides are worth 8 cm and 10 cm, the possible values of the third side are:

RoseWind [281]

Answer:

I'm not sure....

10-8 = 2

lowest point

10+8 = 18

highest point

so the possible values of the third side are:-

3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17

I'm not sure this is what you are looking for but this is my answer....

i hope this helps...

have a great day ahead :)

Plz help with this question can you answer both.

Arlecino [84]

9a. The answer is 1.07% because the function shows an exponential growth in the exponential function.

9b. The first population was about 2622 because it shows that the first year is the domain to find the range of the function when x is equal to 1.
