The temperature at a state park for one day in June can be approximated by the function T(x) = 0.264x2 - 4.752x + 81 0 ≤ x ≤ 18
Lilit [14]

Answer:

  60 °F

Step-by-step explanation:

The function can be put into vertex form:

  T(x) = 0.264(x² -18x) +81 . . . . factor the leading coefficient from 1st 2 terms

Now, we add the square of half the x-coefficient inside parentheses and subtract the same quantity outside parentheses.

  T(x) = 0.264(x² -18x +81) +81 -0.264·81

  T(x) = 0.264(x -9)² +59.616

The low temperature for the day was approximately 59.6 °F, which rounds to 60 °F.

The surface area of a right square pyramid is given by A=b2+2bh where b is the length of a side of the base and h is the slant h
gizmo_the_mogwai [7]

Answer:

h = \dfrac{A - 9}{6}

Step-by-step explanation:

A=b^2+2bh

b = 3

A = 3^2 + 2(3)h

A = 9 + 6h

6h = A - 9

h = \dfrac{A - 9}{6}

select the values that make the inequality h/4 greater than or equal to -1 true then write an equivalent inequality in terms of
jok3333 [9.3K]

Answer:

Values that make it equal:

-4, -3, -1, 0, 4

Written equivalent inequality:

h≥−4

Step by Step for the written inequality:  

h/4 ≥−1

Multiply both sides by 4. Since 4 is positive, the inequality direction remains the same.

h≥−4

I hope this helps you!! :)
