Answer:

See below

Step-by-step explanation:

a.

f(x) = 6x + 9

f(-2) = 6(-2) + 9

f(-2) = -12 + 9

f(-2) = -3

b.

f(x) = 6x + 9

f(x + 7) = 6(x + 7) + 9

f(x + 7) = 6x + 42 + 9

f(x + 7) = 6x + 51

c.

f(x) = 6x + 9

f(-x) = 6(-x) + 9

f(-x) = -6x + 9

The number as (1/2+1/3)3+4 2/3÷7. The mixed number of the simplified number is 3 1/6.

Given that,

The number as (1/2+1/3)3+4 2/3÷7

We have to find the mixed number of the simplified number.

Take,

=(1/2+1/3)3+4 2/3÷7

First solve the 1/2+1/3

=(3+2/6)3+4 2/3÷7

Now adding 3+2

=(5/6)3+4 2/3÷7

Now, divide 3 and 6

=5/2+4 2/3÷7

Now solve the mixed number 4 2/3

=5/2+12+2/3÷7

Now adding 12+2

=5/2+14/3÷7

Now we can write the ÷7 to ×7.

=5/2+14/3×7

Now divide14 and 7

=5/2+2/3

Now take LCM

=5×3+2×2/6

Now multiply 5×3 and 2×2

=15+4/6

Now adding 15+4

=19/6

Now we write in an mixed number.

=3 1/6

Therefore, the mixed number of the simplified number is 3 1/6.

Step-by-step explanation:

Answer:

126 ft

Step-by-step explanation:

V= (area of base) x length

So you work backward and do 1,260 divided by 10 and get 126

Note that the coordinates of the point A' after rotating 90 degrees clockwise about the point (0,1) are (3, -4). (Option B)

To rotate a point 90 degrees  clockwise about a given point,we can follow these steps -

Translate the coordinates   of the given point so that the center of rotation is at the origin.   In this case,we subtract the coordinates   of the center (0,1) from the coordinates of point A (5,4) to get (-5, 3).

Perform the rotation by swapping the x and y coordinates and changing the sign of the   new x coordinate. In this case,we  swap the x and y coordinates of (-5, 3)   to  get (3, -5).

Translate the coordinates back to their original position   by adding the coordinates of the center (0,1)  to the result from step 2. In   this case, we add (0,1) to (3, -5) to get (3, -4).

Therefore, the coordinates   of the point A' after rotating 90 degrees clockwise about the point (0,1) are (3, -4).

Step-by-step explanation:

Scientific notation

To figure out the power of 10 think "how many places do I move the decimal point?"

When the number is 10 or greater the decimal point moves to the left, and the power of 10 is positive.

When the number is smaller than 1 the decimal point moves to the right, so the power of 10 is negative.

Answer:

The walkway should be 2ft wide.

Step-by-step explanation:

Let x be the width of the walkway surrounding the pool.

The area including the pool is 560ft².

Let's solve for the value of x.

The length plus twice the width of the pool is multiplied by the width plus twice the width of the pool. This makes up the whole area.

A = lw

560 = (24 + 2x)(16 + 2x)

560 = 384 + 48x + 32x + 4x²

4x² + 80x + 384 - 560 = 0

4x² + 80x - 176 = 0

Divide the whole equation by 4

x² + 20x - 44 = 0

(x + 22)(x -2) = 0

x = -22; x = 2

Since we are dealing with dimensions, take the one with the positive value.

x = 2ft

Let's check

560ft² = (24ft + 2x)(16ft + 2x)

560ft² = (24ft + 2(2ft)) (16ft + 2(2ft))

560ft² = (24ft + 4ft)(16ft + 4ft)

560ft² = (28ft)(20ft)

560ft² = 560ft² ✔

what's up? it would be D, 180 counterclockwise

a clock consists of 60 minutes, and it is a circle. so 60 minutes would be a full 360 degrees while 30 minutes would be 180 degrees. if it is running fast, in order to set it BACK you'd be going counterclockwise. forward would be clockwise

Answer:

D: 180° Counterclockwise rotation

Step-by-step explanation:

A clock can be thought of as a circle made out of 60 slices of pie, each slice representing one minute. If her clock was running 30 minutes FAST that means it was at the direct opposite side of the clock, because the clock is made of 60 slices, and 30 slices would be half the pie. There are 360° in a circle, and since there is 60 slices, each slice represents 360°/60°= 6°. 30 x 6°= 180°. The rotation would be COUNTER clock wise because the clock is AHEAD, and needs to go back in time; thus going counter to the natural rotation of a clock. 180° counterclockwise.

Answer:

3.5 hours

Step-by-step explanation:

It is given that,

Velocity of first car, v = 20 mph

Velocity of second car, v' = 60 mph

They are moving in opposite direction. Their relative speed is given by :

V = 20 mph + 60 mph = 80 mph

Distance, d = 280 miles

So,

\(t=\dfrac{d}{V}\\\\t=\dfrac{280}{80}\ h\\\\t=3.5\ h\)

Hene, they will be 280 mile apart in 3.5 hours.

Answer:

\(\displaystyle \frac{\pi(5e^4+8e^2-1)}{2e^4}\approx9.526\)

Step-by-step explanation:

This can be solved with either the washer (easier) or the shell method (harder). For the disk/washer method, the slice is perpendicular to the axis of revolution, whereas, for the shell method, the slice is parallel to the axis of revolution.  I'll show how to do it with both:

Shell Method (Horizontal Axis)

\(\displaystyle V=2\pi\int^d_cr(y)h(y)\,dy\)

Radius: \(r(y)=2-y\) (distance from y=2 to x-axis)

Height: \(h(y)=2-(-\ln y)=2+\ln y\) (\(y=e^{-x}\) is the same as \(x=-\ln y\))

Bounds: \([c,d]=[e^{-2},1]\) (plugging x-bounds in gets you this)

Plugging in our integral, we get:

\(\displaystyle V=2\pi\int^1_{e^{-2}}(2-y)(2+\ln y)\,dy=\frac{\pi(5e^4+8e^2-1)}{2e^4}\approx9.526\)

Washer Method (Parallel to x-axis)

\(\displaystyle V=\pi\int^b_a\biggr(R(x)^2-r(x)^2\biggr)\,dx\)

Outer Radius: \(R(x)=2-e^{-x}\) (distance between \(y=2\) and \(y=e^{-x}\))

Inner Radius: \(r(x)=2-1=1\) (distance between \(y=2\) and \(y=1\))

Bounds: \([a,b]=[0,2]\)

Plugging in our integral, we get:

\(\displaystyle V=\pi\int^2_0\biggr((2-e^{-x})^2-1^2\biggr)\,dx\\\\V=\pi\int^2_0\biggr((4-4e^{-x}+e^{-2x})-1\biggr)\,dx\\\\V=\pi\int^2_0(3-4e^{-x}+e^{-2x})\,dx\\\\V=\pi\biggr(3x+4e^{-x}-\frac{1}{2}e^{-2x}\biggr)\biggr|^2_0\\\\V=\pi\biggr[\biggr(3(2)+4e^{-2}-\frac{1}{2}e^{-2(2)}\biggr)-\biggr(3(0)+4e^{-0}-\frac{1}{2}e^{-2(0)}\biggr)\biggr]\\\\V=\pi\biggr[\biggr(6+4e^{-2}-\frac{1}{2}e^{-4}\biggr)-\biggr(4-\frac{1}{2}\biggr)\biggr]\)

\(\displaystyle V=\pi\biggr[\biggr(6+4e^{-2}-\frac{1}{2}e^{-4}\biggr)-\frac{7}{2}\biggr]\\\\V=\pi\biggr(\frac{5}{2}+4e^{-2}-\frac{1}{2}e^{-4}\biggr)\\\\V=\pi\biggr(\frac{5}{2}+\frac{4}{e^2}-\frac{1}{2e^4}\biggr)\\\\V=\pi\biggr(\frac{5e^4}{2e^4}+\frac{8e^2}{2e^4}-\frac{1}{2e^4}\biggr)\\\\V=\pi\biggr(\frac{5e^4+8e^2-1}{2e^4}\biggr)\\\\V=\frac{\pi(5e^4+8e^2-1)}{2e^4}\approx9.526\)

The company spends making tablets each year, you can multiply the number of tablets by the cost per tablet so the company spends about $500 million making tablets each year.

Its origins lie in the Latin word moneta, which was given to the Roman goddess Juno, at whose temple or close by, or both, the Romans first started minting coins approximately 300 BCE.

We may multiply the quantity of tablets produced by the cost of producing each tablet to see how much money the company spends annually making tablets:

Total cost = Production of tablets x Price per tablet

Number of tablets produced =\(2.5 × 10^7\)

Cost per tablet = $20

Therefore, the total cost = \(2.5 × 10^7 × $20 = $5 × 10^8\)

As a result, the corporation spends over $500 million annually producing tablets.
