Write the equation of a line in slope intercept form that has a slope of 4/5 and has a y- intercept of 0

Mathematics
1 answer:
Andreas93 [3]4 years ago
3 0

Answer: y = 4\5*x

We can get this through slope intercept form.

Slope intercept form is y=mx +b where m is the slope and b is the y intercept.

We plug in 4.5 for the slope and 0 for the y-intercept.

Find f(g(3)) given:<br> *<br> f (x) = 2x2 – 1<br> g(x) = 3x<br> h(x) =<br> j(x) = x - 5
bezimeni [28]

Answer:

161

Step-by-step explanation:

Given the functions

f (x) = 2x^2 – 1

g(x) = 3x

we are to find f(g(3))

First look for the composite function f(g(x))

f(g(x)) = f(3x)

f(3x)  = 2(3x)² - 1

f(3x)  = 2*9x² - 1

f(3x)  = 18x² - 1

f(g(x)) =  18x² - 1

Substitute x  = 3 into the result

f(g(3)) = 18(3)² - 1

f(g(3)) = 18*9- 1

f(g(3)) = 162-1

f(g(3)) = 161

Hence f(g(3)) is 161

Can someone please give me the answers to these 2 will add 40 points
Zielflug [23.3K]

Answer:

<h2>Q1. x = 17.1; y = 5.6</h2><h2>Q2. x = 9.7; y = 24.1</h2>

Step-by-step explanation:

Use sine and cosine.

sine=\dfrac{opposite}{hypotenuse}

cosine=\dfrac{adjacent}{hypotenuse}

Q8.

We have:

opposite=y\\\\adjacent=x\\\\hypotenuse=18\\\\\alpha=18^o\\\\\sin18^o\approx0.309\\\\\cos18^o\approx0.9511

Substitute:

\dfrac{y}{18}=0.309            <em>   multiply both sides by 18</em>

y=5.562\to y\approx5.6

\dfrac{x}{0.9511}=18             <em>multiply both sides by 0.9511</em>

x=17.1198\to x\approx17.1

Q9.

We have:

opposite=y\\\\adjacent=x\\\\hypotenuse=26\\\\\alpha=68^o\\\\\sin68^o\approx0.9272\\\\\cos68^o\approx0.3746

Substitute:

\dfrac{y}{26}=0.9272             <em>multiply both sides by 26</em>

y=24.1072\to y\approx24.1

\dfrac{x}{26}=0.3746          <em>multiply both sides by 26</em>

x=9.7396\to x\approx9.7

An angle with a measure of would be classified as which type of angle? a. acute b. obtuse c. right d. straight
REY [17]

Since the given angle is less than 60 degrees which is less than 90 degrees, hence the measure that would be classified as the given angle is acute angle.

<h3>Lines and angle</h3>

A line is the shortest distance between two points where. the points where two lines meet is an angle.

There are several types of angles including acute, obtuse, right and straight

For acute angle, the angle is less than 90 degrees

For obtuse, the angle is greater than 90 and less than 180 degrees

For right angle, the angle is 90 degrees

Since the given angle is less than 60 degrees which is less than 90 degrees, hence the measure that would be classified as the given angle is acute angle.
