Answer:

y = 4x - 11

Step-by-step explanation:

Point-Slope Form: [tex](y-y_0)=m(x-x_o)[/tex]

Given information:

y = 4x - 7. Through (3,1)

m = 4.

Thus, using m = 4 and point (3,1) in Point-Slope Form can make another equation that is parallel to y = 4x - 7.

[tex](y-y_0)=m(x-x_o)\\\\(y-(1))=4(x-(3))\\\\y-1=4(x-3)\\\\y-1=4x-12\\\\y=4x-11[/tex]

Answer:

[tex]\sf x=\boxed{18.21}[/tex]

Step-by-step explanation:

Assuming this is a right triangle.

Trigonometric ratios

[tex]\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}[/tex]

where:

Given:

[tex]\implies \sf \tan(35^{\circ})=\dfrac{x}{26}[/tex]

[tex]\implies \sf x=26\tan(35^{\circ})[/tex]

[tex]\implies \sf x=18.20539599...[/tex]

Therefore, x = 18.21 (nearest hundredth)

$48,000 a year is $1,846.15 biweekly before taxes and approximately $1,384.62 after taxes. Paying a tax rate of around 25% and working full-time at 40 hours a week, you would earn $1,384.62 after taxes. To calculate how much you make biweekly before taxes, you would multiply $23.08 by 40 hours and 2 weeks

Answer:

$48,000 ÷ 26 = $1,846.15

Answer:

you were thinking of 41

Step-by-step explanation:

(x-9)*4=128

(x-9)=128/4

(x-9)=32

x=32+9

x=41

Answer:

41

Step-by-step explanation:

Let n be the number

Subtract 9

n-9

Multiply this by 4

4(n-9)

The result is 128

4(n-9)=128

To find the number divide each side by 4

4(n-9)/4=128/4

n-9 = 32

Add 9 to each side

n-9+9 = 32+9

n = 41

Hi!

Your answer is [tex]5x^2-7x-8[/tex].

We are asked:

[tex](-3x^2-5x+1)+(8x^2-2x-9)[/tex]

As we are adding them, we can remove the parenthesis.

[tex]-3x^2-5x+1+8x^2-2x-9[/tex]

Now, we can switch the order of the terms around to cause like terms to be by each other:

[tex]-3x^2+8x^2-5x-2x+1-9[/tex]

Finally, add like terms:

[tex]5x^2-7x-8[/tex]

5x² -7x -8 is the result of adding the polynomials -3x²-5x +1 and 8x²-2x-9. The result obtained by combining the like terms.

The two polynomials are  -3x²-5x +1 and 8x²-2x-9.

To add the two polynomials, you simply combine like terms.

Like terms are terms that have the same variable raised to the same power.

In this case, the variables are x² and x.

Let's add the given polynomials:

= -3x²-5x +1 + 8x²-2x-9

Group the like terms:

= -3x²+ 8x²-5x-2x+1-9

Combine like terms:

= 5x² -7x -8

Hence, 5x² -7x -8 is the result of adding -3x²-5x +1 and 8x²-2x-9.

Answer:See the attached figure. The original triangle is shown in red (triangle ABC). The line of reflection is the blue dashed line. This is the equation y = x. Reflecting triangle ABC over the line y = x results in the purple triangle A'B'C'.

Note how the x and y values swap places.

We have...

point A = (5,1) turn into point A' = (1,5)

point B = (8,1) turn into point B' = (1,8)

point C = (8,6) turn into point B' = (6,8)

The swap occurs because the rule (x,y) --> (y,x) tells this to happen.

The purple triangle is the final answer.

She can take one of 3 blue toys from 5 toys (I hope that you know what I mean)

Her chance is 3/5 to take the blue one

Step-by-step explanation:

First we need to get his speed:

speed = distance / time

If he travelled 24 miles in 20 mintues, his speed is 24 / 20 = 1.2 miles per minute

If he travelled 18 miles in 15 minutes, his speed is 18 / 15 = 1.2 miles per minute

Those two should give us the same answer since it says that the distance varies linear with time, which means that his speed is constant.

Then after 30 minutes he will have traveled: 1.2 x 30 = 36 miles

[tex]\textsf{P(Renae catches no.28 bus then reads a book)}= \dfrac{1}{12}[/tex]

Part (c)

Her activity does not depend on which bus she takes, as we have been told that once she is on the bus, she randomly selects the activity.  Therefore, the activity selection is independent from the bus selection.

The sample space confirms this as it shows that the probability of the selecting each activity is equally likely for each of the 4 buses.

The expression that represents the volume of the composite figure is 16/3πr³ + r³

The given parameters are:

The volume of a cube is:

V = l³

So, we have:

V = r³

The volume of a hemisphere is:

V = (2/3)πr³

So, we have:

V = (2/3)π(2r)³

Evaluate

V = (2/3)π * 8r³

This gives

V = 16/3πr³

Add both volumes

Volume = 16/3πr³ + r³

Hence, the expression that represents the volume of the figure is 16/3πr³ + r³

Answer:

Set up an equation using these key terms:

Form the equation by piecing these key terms together:

63/100(63%) ×(of) X(The number being sought) = 792("-is 792)

63/100 × X = 792

(63/100 can be simplified to 0.63)

So, rewrite the equation to:

0.63 × X = 792

Solve for x!

0.63x = 792

Isolate 'x' by dividing 0.63 from both sides because the inverse operation of multiplication is division.

÷0.63 ÷0.63

x = 1,257.14285714 which can be rounded to 1,257.14.

Therefore, the number being sought is 1,257.14.

Remark

The base of the figure is a pentagon

The area of the base of a pentagon is

A=(1/4) * √[5(5+2√5)] * s2

The Formula for the Volume of a "pyramid" of this nature is

Volume = Base * h / 3

Givens

h = 10 feet

s = 8 feet

Base = formula in the remark section

Solution.

Find the base first.

A=(1/4) * √[5(5+2√ 5)] * s2     Find the value of 5 + 2√5

Area = 0.25√[5*(9.47)] * s^2 Find what is under the root sign

Area = 0.25√47.36   * s^2     Take the square root of 47.36. use s = 8

Area = 0.25 * 6.88 * 8^2         Combine.

Area = 110.11

Now find the volume

V = B * h/3

V = 110.11 * 10 / 3

V = 367.04     cubic feet.

Step-by-step explanation:

When a polynomial is shown in factored form, its zeros are the values of x that make the factors zero.

  The factor x is zero when x=0.

  The factor (x+4) is zero when x=-4.

  The factor (x+5) is zero when x=-5.

__

The multiplicity of a zero is the number of times a given factor is a factor of the polynomial. It is the exponent of the factor.

 x = 0 has multiplicity 3.

  x = -4 has multiplicity 2.

  x = -5 has multiplicity 2.

Answer:

Your answer is C, 14ft

Step-by-step explanation:

Your Given Measurements (in feet):

Height = 5 1/2 ; Width = 1 1/2

___________________________________________________

The Perimeter Formula:

L + W + L + W = P

In this case, the "L" which is length going to get substituted as Height.

5 1/2 is 5.5 because if you do 1/2 on the calculator, you get 0.5 which you can add 5 to get 5.5.

1 1/2 is 1.5 which is the same as the 5 1/2.

____________________________________________________

Now do 5.5 + 1.5 + 5.5 + 1.5 = perimeter

5.5 + 1.5 = 7

7 + 7 = 14ft

Your answer is C: 14 ft
