The graph of an exponential function passes through (1, 10) and (4, 80). Find the function that describes the graph.

svetlana [45]

Answer:

y = 5*2ˣ

Step-by-step explanation:

Exponential function:

y = abˣ

Ordered pairs given:

(1, 10) and (4, 80)

Substitute x and y values to get below system:

10 = ab
80 = ab⁴

Divide the second equation by the first one and solve for b:

80/10 = b³
b³ = 8
b = ∛8
b = 2

Use the first equation and find the value of a:

10 = a*2
a = 5

The function is:

y = 5*2ˣ

Suppose sin(A) = 1/4. use the trig identity sin^2(A)+cos^2(A)=1 to find cos(A) in quadrant II. around to ten-thousandth.

larisa86 [58]

In quadrant II, $\cos(A)$ will be negative. So

$\sin^2(A) + \cos^2(A) = 1 \implies \cos(A) = -\sqrt{1 - \sin^2(A)} = -\dfrac{\sqrt{15}}4 \approx \boxed{-0.9682}$
