Muhammad ate an average of 2.5% cookies per day

1 answer:

5 0

A = 2.5x , where x = 7 since there is 7 days in a week. So it would be 2.5(7)

B = 2.5(30) where 30 represents how many days. So he eats 75 cookies in 30 days.

Correct me if I am wrong.

The graph of a quadratic function has a vertex at (5,3) and goes through the point (-1,-9). What is the equation of the function

kotegsom [21]

Answer:

$y=-\frac{1}{3} (x-5)^2+3$

Step-by-step explanation:

We are given the following;

Vertex of a quadratic function = (5,3)
A point where the function passes through (-1, -9)

Required to determine the equation of the function;

We need to know the vertex form of a quadratic function is;

$y=a(x-h)^2+k$ , where h and k correspond to the vertex (h,k)

Therefore, we can replace the variables h and k of the vertex in the equation;

That is;

$y=a(x-5)^2+3$

Then we use the equation and the point given to solve for a

x = -1 and y = -9

We get;

$-9=a(-1-5)^2+3\\-9 = a(36) + 3\\-9 - 3 = 36a\\-12 =36a \\a=-\frac{1}{3}$

Substituting the values of a, h and k in the equation, we get;

$y=-\frac{1}{3} (x-5)^2+3$

Thus, the equation of the function in the vertex form is $y=-\frac{1}{3} (x-5)^2+3$

Te g (3) if g (x) = 2x + 2.

creativ13 [48]

Answer:

g(3) = 8

Step-by-step explanation:

To evaluate g(3) substitute x = 3 into g(x)

g(3) = 2(3) + 2 = 6 + 2 = 8

How I can find the angles of romboys

denis23 [38]

Answer:

To find the area of a rhombus, multiply the lengths of the two diagonals and divide by 2 (same as multiplying by 1/2): The sides and angles of a rhombus: The sides of a rhombus are all congruent (the same length.) Opposite angles of a rhombus are congruent (the same size and measure.)
