Solve this I need it solved

Answer:

option 3

Step-by-step explanation:

$Standard \ quadratic \ equation : ax^2 + bx +c$

Larger the value of '' a '' makes the parabola narrow.

A positive value of '' a '' which is close to 0 makes the parabola wide.

To find the widest graph , find the smallest a. (or a closest to zero)

option 1

$a_1 = \frac{1}{3}$

option 2

$a_2 = - \frac{4}{5}$

option 3

$a_3 = 0.3 = \frac{3}{10}$

option 4

$a_4 = -4$

Positive and negative value of ' a ' decides the direction the parabola opens.

But we have to find the widest parabola irrespective of the direction.

So we will find the smallest ' a '

$a_1 = 0.33\\a_2 = 0.80\\a_3 = 0.30\\a_4 = 4$

$a_3 \ is \ the \ smallest \ number \ or\ \\ the \ number \ closest \ to\ zero.\\\ so \ option \ 3 \ makes\ the\ widest \ parabola.$

Ben made a model (shown below) of the square pyramid he plans to build when he grows up. Find the surface area of the model.

OverLord2011 [107]

Answer:

The surface area of the model is $SA=240\ m^{2}$

Step-by-step explanation:

we know that

The surface area of the square pyramid is equal to the area of the square base plus the area of four lateral triangles

$SA=10*10+4(\frac{1}{2}(10)(7))\\ SA=100+140\\SA=240\ m^{2}$

PLEASE HELP WILL GIVE BRAINLIEST TO CORRECT ANSWER What is the slope of this line?

Alla [95]

Choice two point from the graph (look at the picture).

(0, 2) and (3, -2).

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Substitute:

$m=\dfrac{-2-2}{3-0}=\dfrac{-4}{3}=-\dfrac{4}{3}$

Answer: The slope of this line is $\boxed{m=-\dfrac{4}{3}}$
