Multiply the two values together. 7.62 x 1.23 = 9.3726
10^2 x 10^4 = 10^6.
9.3726 x 10^6 is the answer in Scientific Notation.
4(2) - 5 = 3
4(5) - 5 = 15
4(8) - 5 = 27
4(9) - 5 = 31
so the answers are 3, 15, 27, and 31
Answer:
y = - 3x² - 24x - 60
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (- 4, - 12 ), thus
y = a(x + 4)² - 12
To calculate a substitute (- 7, - 39) into the equation
- 39 = a(- 7 + 4)² - 12 ( add 12 to both sides )
- 27 = 9a ( divide both sides by 9 )
- 3 = a
y = - 3(x + 4)² - 12 ← in vertex form
Expand (x + 4)²
y = - 3(x² + 8x + 16) - 12
= - 3x² - 24x - 48 - 12
y = - 3x² - 24x - 60 ← in standard form
= - 3(x²
#18
Answer C
4*7 = 28 which is the most closest one to 27.8
#19
perimeter = 2(L+W)
175.33 feet = 2103. 96 in
2 ( 2103.96 +48)
2 * 2151.96
4303.92 inches
#20
L*W = A
2103.96 * 48
100990.08 inch^2
to lazy to do the rest sorry
