Answer:
The answers would be =
A = (226.6 + 205.6 + 157.6) / 3 = 589.8 / 3 = (196.6)
B = (119.6 + 61.6 )/2 = 181.2/2 = 90.6
Answer:
cos B = 9/41
Step-by-step explanation:
Using trig functions, since we have a right angle,
cos theta = adjacent side/ hypotenuse
Cos B = 18/82
Dividing the right side by 2
cos B = 9/41
Answer:
a = 1, b = 3, c = 1, d = 2, e = 6, and f = 8
Step-by-step explanation:
The given exponential functions are;
2ˣ, 3·2ˣ, and ![2^{3 \cdot x}](https://tex.z-dn.net/?f=2%5E%7B3%20%5Ccdot%20x%7D)
Let f(x) = 2ˣ, h(x) = 3·2ˣ, and g(x) = ![2^{3 \cdot x}](https://tex.z-dn.net/?f=2%5E%7B3%20%5Ccdot%20x%7D)
From the table for investigating the dilations of exponential function, we have;
a = f(0) = 2⁰ = 1
b = h(0) = 3·2⁰ = 3 × 1 = 3
c = g(0) =
= 2⁰ = 1
d = f(1) = 2¹ = 2
e = h(1) = 3·2¹ = 3 × 2 = 6
f = g(1) =
= 2³ = 8.
Answer:
![-\frac{3}{7}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B7%7D)
Step-by-step explanation:
The additive inverse of a number (its "opposite") is what you add to the given number to get a sum of zero.
![\frac{3}{7} + (-\frac{3}{7}) =0](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B7%7D%20%2B%20%28-%5Cfrac%7B3%7D%7B7%7D%29%20%3D0)
