Answer:
f(g(x)) = 50x² + 140x + 93
Step-by-step explanation:
f(g(x)) means that within the f(x) equation, you want to replace all of the x variables with the g(x) equation.
So,
f(g(x)) = 2 (5x+7)² -5
= 2 ( 25x²+ 70x + 49) - 5
= 50x² + 140x + 93

Find the H.C.F. of the following expressions:36(x³+x²y-12xy²), 54(x³y+4x³y²-21xy)
Answer:
18x
Step-by-step explanation:
The HCF is the highest factor common to both expressions. We can find it by factoring both expressions and identifying common factors.
Factorization
36(x³+x²y-12xy²) = 18x·2·(x +4y)(x -3y)
54(x³y+4x³y²-21xy) = 18x·3y·(x +7)(x -3)
The highest common factor is 18x.

So in this case case it appears there is only 1 mode with that being 6, since it appears 3 times. with no other value appearing this much in the data set.
Write the equation of the line that passes through the points (1,1) and (2,4). Write your answer in slope intercept form. Step by step please
Answer: y = 3x - 2
Step-by-step explanation:
gradient = (4 - 1)/(2 - 1) = 3/1 = 3
y = 3x + c needs to work for both points

Write an equation in slope-intercept form of the line that passes through the point (3,-2) with slope -2.
Answer:
D
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = - 2 , then
y = - 2x + c ← is the partial equation
to find c substitute (3, - 2 ) into the partial equation
- 2 = - 6 + c ⇒ c = - 2 + 6 = 4
y = - 2x + 4 ← equation of line in slope- intercept form

Mark decided to make Christmas presents for his classmates. he bought 10lb of two types of candies: caramel candies for $2.80 per pound and chocolate candies for $3.50 a pound.
Write a function f(x) that represents the total cost of candy, where x is the weight of the less expensive candy
Brainliest for correct answer
The function for the given situation is f(x)=35.0-0.7x.
Given that, Mark bought 10 pound of two types of candies, caramel candies for $2.80 per pound and chocolate candies for $3.50 a pound.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Now, the function for the given situation is as follows:
If x is the weight of the less expensive candy, the 10-x is the weight of the high expensive candy.
So, f(x)=2.80x+3.50(10-x)
⇒ f(x)=2.80x+35.0-3.50x
⇒ f(x)=35.0-0.7x
Therefore, the function for the given situation is f(x)=35.0-0.7x.

Let define some variables,
D is the midline, this refers to the midpoint of the highest y value and lowest y value. Some textbooks call it the vertical translations but it is the same thing.
A is the amplitude. The amplitude is the distance from the midline to the highest y value. Some distance is non negative, the formula for the amplitude is
[tex] |a| [/tex]
The period is how often the wave repeats itself on a interval.
Period can't be negative so the formula for period is
[tex] \frac{2 \pi}{ |b| } [/tex]
To find the period, look at the extreme points.
The phase shift tells us if the sinusoid have been shifted to the right or left. The formula for the phase shift
[tex]bx + c = 0[/tex]
Solving for x gives us
[tex]x = \frac{ - c}{b} [/tex]
If our x is negative, we have a phase shift to the right
If our x is Positve, we have a phase shift to the left.
Let solve this equation, Let use Sine since sin(0)=0,
The smallest y value here is 0, and the highest is 2, so the amplitude is 1.
[tex]d = 1[/tex]
Next, the distance from the max to the midline is 1, as well the min to the midline is also 1.
So
[tex]a = 1[/tex]
We have minimum at 0, and 8, so our period is 8.
[tex] \frac{2\pi}{b} = 8[/tex]
Solve for b,
[tex] \frac{\pi}{4} = b[/tex]
Plug this in the equation.
[tex]1 \sin( \frac{\pi}{4} x) + [/tex]
[tex]y = \sin( \frac{\pi}{4} x) + 1[/tex]
The graph passes through (4,2) so let see if that holds true for our equation
[tex]2 = \sin( \frac{\pi}{4} (4)) + 1[/tex]
[tex]2 = \sin(\pi) + 1[/tex]
[tex]2 = 0 + 1[/tex]
[tex]2 = 1[/tex]
This doesn't hold true, so we must have a phase shift
Notice that
[tex] \sin( \frac{\pi}{2} ) = 1[/tex]
So if we shift this pi/2 to the right, we can get our equation to be true.
[tex]y = \sin( \frac{\pi}{4} x - \frac{\pi}{2} ) + 1[/tex]
This equation works so our equation is
[tex]y = \sin( \frac{\pi}{4} x - \frac{\pi}{2} ) + 1[/tex]
65 people took a clarinet exam. Before the exam, 23 people predicted that they would pass, and the rest predicted they would fail. Of the people who predicted they would pass, 18 actually did. In total, 31 people passed the clarinet exam. What fraction of those who thought that they would fail actually did fail?
Answer:
The answer is 29/42
Step-by-step explanation:
First, let's calculate how many people predicted they would fail. The question states that 65 people took the exam and 23 predicted they would pass, so we can find the number of people that predicted they would fail by the following calculation:
Let FP be the people who predicted they'd fail
65 = 23 + FP
65 - 23 = FP
42 = FP
Now, let's move on to the next part. The question states that a total of 31 people passed the test, from those 18 being the people who predicted they would pass and the rest are people who had predicted they would fail but ended up passing.
Let's set x as the number of people who predicted they would fail but have passed.
31 = 18 + x
31 - 18 = x
13 = x
Since 13 of the 42 FP have passed, we can calculate how many of them failed. Let y be the number of people that predicted to fail and ended up failing:
13 + y = 42
y = 42 - 13
y = 29
Finally, now we have the fraction of those who predicted that they would fail actually did fail and that's 29/42
