Write an equation that has a hole at x = 4 and a vertical asymptote at x = -3.

Answers

Answer 1

This has to be a rational equation in order to have those characteristics...in other words a fraction. One such equation would look like this:
x^2 - 2x - 8/x^2 - x - 12. When you factor both the numerator and the denominator you get (x-4)(x+2)/(x-4)(x+3). Because the (x-4) is in both the top and the bottom of the fraction, you can cancel them out, which makes that (x-4) a removable discontinuity. The (x+3) exists as a vertical asymptote.

Annie has a compost pile that produces 12 pounds of compost a day from yard waste. Which function expresses the amount of compost (c) as a function of the number of days (d)? The function representing the relationship between the amount of compost and the number of days is__, with the input as__.

Answers

If it produces 12 pounds each day, for any number of days, we can just multiply by 12, correct?? So that means c=12d. Remember your input will be the days since you have to put that in the equation to calculate how much compost you have.

B) A number line with an open circle on 2, a closed circle on 6, and shading in between
C) A number line with a closed circle on 2, shading to the left, and an open circle on 6, shading to the right
D) A number line with a closed circle on 2, an open circle on 6, and shading in between

Answers

To do this, you first have to solve the first inequality for x: 2x+5>9, 2x>4 and x>2. Now solve the next one for x as well: 5x <=30, x<=6. Now work on putting them onto a number line together. Since there is not an "equal to" with that greater than, the circle is open above the 2. The next one has an "equal to" with it so that's a closed circle above the 6. This is a conjunction, meaning the solution will show what is shared between the 2 inequalities, so you have an open circle above the 2 and shading to the right til you get to the closed circle above the 6 (which is technically shaded to the left down to the open circle at 2). So your choice is B.

Answer:

B) A number line with an open circle on 2, a closed circle on 6, and shading in between

express 3/4, 7/16,and 5/8 with the LCD

Answers

The LCD (lowest common denominator) is the lowest common denominator of two or more fractions.

4 = 2²
16 = 2⁴
8 = 2³

Take common and non-common factors with highest exponent.

So LCD = 16

The new dneominator of all fractions is 16. Divide this number for the original denominators and multiply for numerator...

16/4 = 4
4*3 = 12

3/4 = 12/16

16/16 = 1
1*7 = 7

7/16 = 7/16

16/8 = 2
2*5 = 10

5/8 = 10/16

A line with a slope of 3 passes through the point (2,5) what is the equation of this line?

Answers

y=3x-4 because the form of a line's equation is y=mx+b where m is the slope or three in this case and b is the value of y in the y intercept and in this case it is -4 so you get y=3x+(-4) or y=3x-4.

Slope of the line equals 3 at the points (2,5) so m=0
The equation is a horizontal line, therefore the slope is 0.

In a circle with an 8-inch radius, a central angle has a measure of 60°. How long is the segment joining the endpoints of the arc cut off by the angle?

Answers

calculate circumference first:

C = 2πr
C = 2(3.14159)(8 inches)
C = 50.265 inches

then 60/360 = 1/6 of the circle

50.265 inches / 6
= 8.378 inches (Round answer as needed)

Answer:

The length of segment joining the endpoints of the arc is [tex]8\ in[/tex]

Step-by-step explanation:

we know that

In the triangle ABC

see the attached figure to better understand the problem

[tex]AC=BC[/tex] -----> is the radius of the circle

[tex]m<CAB=m<CBA[/tex]

[tex]m<ACB=60\°[/tex] ----> given problem (central angle)

Initially the triangle ABC is an isosceles triangle

Remember that

the sum of the internal angles of triangle must be equal to [tex]180\°[/tex]

For this particular case, the isosceles triangle ABC becomes an equilateral triangle, as the three angles are equal to [tex]60\°[/tex]

The equilateral triangle has three equal sides and tree equal angles

[tex]AC=BC=AB[/tex]

Hence

The length of segment joining the endpoints of the arc is [tex]8\ in[/tex]

The pressure P exerted by a force varies inversely as the area A on which the force is applied. If 16 N/ft2 of pressure is exerted by a force on an area of 3 ft2 , what is the pressure exerted by the same force on an area of 6 ft2?
A) 8 N/ft2
B) 16 N/ft2
C) 4 N/ft2
D) 32 N/ft2

Answers

The first piece of information tells you that
16 = C / 3
Solve for C
C=16×3=48
Now find P if A = 6. and C=48
P = C/6
P = 48/6
P = 8 N/ft2

Answer:

A) 8 N/ft2

Step-by-step explanation:

Pressure is the normal force per unit area, that is, it is equivalent to the force acting on the surface unit, and is given by:

[tex]P=\frac{F}{A}[/tex]

Where:

[tex]P=Pressure\\F=Normal\hspace{3}force\\A=Area\hspace{3} where \hspace{3}force\hspace{3} is \hspace{3}applied.[/tex]

In the first case:

[tex]P=16N/ft^2\\A=3ft^2[/tex]

Using the previous equation and solving for [tex]F[/tex] :

[tex]F=P*A=16*3=48N[/tex]

Now, for the second case, since the force is the same applied in the first case, then:

[tex]P=\frac{F}{A} =\frac{48}{6} =8N/ft^2[/tex]

Therefore the answer is:

A) 8 N/ft2

Use 1% or 10% to estimate 8% of 310

Answers

We can obtain 8% of a value by finding the 10% of the value and subtract 2% of the value

10% of 310 = 310÷10 = 31
1% of 310 = 310÷100 = 3.1
2% of 310 = 2×3.1 = 6.2

8% of 310 = 31 - 6.2 = 24.8

What is the taxi distance between A(2, 5) and B(7, 9)?

Answers

If by "taxi distance" you mean travelling along the sides of the right triangle created by the two points.

t=|x2-x1|+|y2-y1|

t=5+4

t=9 units

If you mean the actual distance between the two points then:

d^2=(x2-x1)^2+(y2-y1)^2

d^2=(7-2)^2+(9-5)^2

d^2=25+16

d^2=41

d=√41 units

d≈6.4 units (to nearest tenth of a unit)

Find the measure of each exterior angle of a regular polygon with 24 sides

Answers

the measure of each interior angle would be 165 degrees

The formula for finding the measure of each exterior angle of a regular polygon is similar to the formula for finding the measure of each interior angle. We take the sum of the measures of the exterior angles which is always 360 degrees and we divide this by the number of sides in the polygon which is n. So the formula for finding the measure of each exterior angle of a regular polygon is simply 360 over n. In this problem since the polygon has 24 sides, we simply plug a 24 in for n and we have 360 over 15. 360 divided by 24 is 15. Therefore, the measure of each exterior angle of a regular polygon that has 24 sides is 15 degrees.

Given tan A = .78 find angle A in degrees. Round your answer to the nearest hundredth.

Answers

Tangent is one of the simplest trigonometric functions which relates the sides of the triangle. This function is the ratio between the measure of the side opposite to the angle and the side adjacent to it. This can be calculated through the reverse equation of,
tan⁻¹(0.78) = A
The value of A in the equation to the nearest hundredth is 37.95°.

Answer:

[tex]A\approx 37.95^{\circ}[/tex]

Step-by-step explanation:

We have been given that [tex]\text{tan}(A)=0.78[/tex]. We are asked to find measure of angle A in degrees.

We will inverse tangent to find measure of angle A as:

[tex]A=\text{tan}^{-1}(0.78)[/tex]

[tex]A=37.954230875133^{\circ}[/tex]

Upon rounding our answer to nearest hundredth, we will get:

[tex]A\approx 37.95^{\circ}[/tex]

Therefore, the measure of angle A is approximately 37.95 degrees.

A surveyor measures the angle of elevation to a point on a mountain to be 18 degrees the point on the mountain is horizontally 4 miles away from the surveyor the vertical change in elevation from the point where the surveyor is standing to the point on the mountain is___ miles?

Answers

This is right triangle trig and you are looking for the height of the triangle. The reference angle is 18 degrees, the side adjacent to that angle is 4 and you are looking for the side opposite the reference angle. The trig identity that helps us find that missing side is tangent:
[tex]tan(18)= \frac{x}{4} [/tex]
and 4 tan(18) = x.
x = 1.3 miles

Answer:

1.3 miles

Step-by-step explanation:

Solution:-

- The surveyor stands at a platform that is B = 4 miles and at an elevation of θ = 18 ° away from the point on the mountain.

- We can construct a right triangle from surveyor to the point of observation. To determine the change in height/elevation (H) we will apply the trigonometric relation as follows:

tan ( θ ) = H / B

- Solve for the elevation (H):

H = B*tan ( θ )

H = 4*tan ( 18 )

H = 1.3 miles

- The change in elevation from surveyor to point of observation is H = 1.3 miles.

[tex]x= \frac{3}{4} y[/tex] (equation 1)
