Answer:
33
Step by Step:
8w^2+2w-3
Substitute in the value 2 for w
8(2)^2+2(2)-3
Solve exponents first:
8(4)+2(2)-3
Solve grouping symbols:
32+4-3
Simplify the equation:
33
r=-3, n=8, a_1=3
S = 3(1 - (-3)^8)/(1 - -3) = -4920
Choice C
It’s 27 miles i believe! 4.5 times 6 is how you get it! hope this helps
Answer:
Step-by-step explanation:
a) Input = -9 ⇒ x = -9
y = x² + 3
Plugin x = (-9),
y = (-9)² + 3
= 81 + 3 {(-9)² = -9 * (-9) = 81}
y = 84 ---> Output
y = √x - 2
= √-9 - 2 { i² = -1}
y = 3i - 2 ------> Output
b) Output = 0
y = x² + 3
x² + 3 = 0
x² = -3
y = √x -2
0 = √x - 2
√x = 2
Take square,
