Which equation when graphed has a maximum value at x = −2? A) y = −x2 − 20x − 16, B) y = −x2 − 16x − 12, C) y = −4x2 − 20x − 16,

KonstantinChe [14]

Answer:

Option D. $y=-4x^{2} -16x-12$

Step-by-step explanation:

using a graphing tool

Graph and determine the vertex in each case

we know that

If the equation has a maximum value at x=-2, then the x-coordinate of the vertex must be equal to -2 and the parabola open downward

case A) $y=-x^{2} -20x-16$

The vertex is the point $(-10,84)$

case B) $y=-x^{2} -16x-12$

The vertex is the point $(-8,52)$

case C) $y=-4x^{2} -20x-16$

The vertex is the point $(-2.5,9)$

case D) $y=-4x^{2} -16x-12$

The vertex is the point $(-2,4)$ -------> is the answer

Toski is building a room that is 18 feet long and 14 feet wide. Construct a scale drawing of the shed. Use a scale of inch = 2 f

AURORKA [14]

Answer:

Option A is the answer

Step-by-step explanation:

Toski is building a room having length = 18 feet

Width of the room = 14 feet

Scale has been given as 1 inch = 2 feet

∵ 2 feet = 1 inch

∴ 1 feet = $\frac{1}{2}$ feet

∴ 18 feet length of the room = $\frac{18}{2}=9$ inches

Similarly 14 feet width of the room = $\frac{14}{2}=7$ inch

Now we count the small blocks in the given options.

Option A has 9 blocks or 9 inches as the length of the room and 7 blocks or 7 inches as the width of the room.

Option A is the answer.

A school principal estimates that no more than 6% of this years senior class will graduate with honors. There are 350 students.

vovikov84 [41]

<span>Given there is no more of 6% of students graduates with honors, and there is a total of 350 senior class students. All you have to do is multiply 350 to 6% or simply get 6% from 350.
To get the answer: 350 students * .06 = 21 students.
Therefore, no more than 21 students will graduate with honors in the senior class batch.</span>
