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:

<u>Exponential function:</u>

y = abˣ

<u>Ordered pairs given:</u>

(1, 10) and (4, 80)

<u>Substitute x and y values to get below system:</u>

10 = ab
80 = ab⁴

<u>Divide the second equation by the first one and solve for b:</u>

80/10 = b³
b³ = 8
b = ∛8
b = 2

<u>Use the first equation and find the value of a:</u>

10 = a*2
a = 5

<u>The function is:</u>

y = 5*2ˣ

Solve the triangle A = 2 B = 9 C =8

VARVARA [1.3K]

Answer:

$\begin{gathered} A=\text{ 12}\degree \\ B=\text{ 114}\degree \\ C=54\degree \end{gathered}$

Step-by-step explanation:

To calculate the angles of the given triangle, we can use the law of cosines:

$\begin{gathered} \cos (C)=\frac{a^2+b^2-c^2}{2ab} \\ \cos (A)=\frac{b^2+c^2-a^2}{2bc} \\ \cos (B)=\frac{c^2+a^2-b^2}{2ca} \end{gathered}$

Then, given the sides a=2, b=9, and c=8.

$\begin{gathered} \cos (A)=\frac{9^2+8^2-2^2}{2\cdot9\cdot8} \\ \cos (A)=\frac{141}{144} \\ A=\cos ^{-1}(\frac{141}{144}) \\ A=11.7 \\ \text{ Rounding to the nearest degree:} \\ A=12º \end{gathered}$

For B:

$\begin{gathered} \cos (B)=\frac{8^2+2^2-9^2}{2\cdot8\cdot2} \\ \cos (B)=\frac{13}{32} \\ B=\cos ^{-1}(\frac{13}{32}) \\ B=113.9\degree \\ \text{Rounding:} \\ B=114\degree \end{gathered}$ $\begin{gathered} \cos (C)=\frac{2^2+9^2-8^2}{2\cdot2\cdot9} \\ \cos (C)=\frac{21}{36} \\ C=\cos ^{-1}(\frac{21}{36}) \\ C=54.3 \\ \text{Rounding:} \\ C=\text{ 54}\degree \end{gathered}$

Tema [17]

Answer:

(c) $h(3) = 1$

Step-by-step explanation:

Given

The attached graph

Required

Find h(3)

The formula to use in solving this is:

$y = h(x)$

Substitute 3 for x

$y = h(3)$

From the attached graph, the value od x = 3 points to the value of y = 1.

So, we have:

$y = 1$

PLEASE HELP ME. NO PHONY ANSWERS TY, ANSWER IF YOUR 100% RIGHT!

Ksivusya [100]

The relative frequency of female mathematics majors will be 0.5142.

<h3>How to find the relative frequency?</h3>

The proportion of the examined subgroup's value to the overall account is known as relative frequency.

A sample of 317 students at a university is surveyed.

The students are classified according to gender (“female” or “male”).

The table is given below.

Then the relative frequency of female mathematics majors will be

⇒ 36 / (36 + 34)

⇒ 36 / 70

⇒ 0.5142
