Give some examples of perpendicular lines inside or outside your classroom.

Answer:

30%

Step-by-step explanation:

1) Find the amount of time left to complete

60 minutes total - 42 minutes already played = 18 minutes left

2) Divide the amount of minutes left by the total minutes

18 minutes left ÷ 60 minutes total = 0.3

3) Multiply that value by 100 to turn the decimal into a percent

0.3 * 100 = 30%

Answer:

30%

Step-by-step explanation:

The answer is thirty percent. One way to solve this problem is to start by finding what percent of Vanessa’s practice time forty-two minutes represents.

Let p represent the unknown percent, and set up a proportion that compares the like ratios of parts to wholes.

Divide out the like minutes and cross multiply.

Divide both sides by sixty to solve for the percent of time Vanessa has already practiced.

Subtract seventy percent from one hundred percent to determine the percent of time she has left to practice.

Vanessa still has thirty percent of her practice time to complete.

The value of x will be;

⇒ x = 8

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

C = 3 and d = 2,

And, The equation is,

⇒ x = 2C + d

Here,

The values are,

⇒ C = 3 and d = 2,

Substitute above value in equation , we get;

⇒ x = 2C + d

⇒ x = 2 × 3 + 2

⇒ x = 6 + 2

⇒ x = 8

Thus, The value of x = 8.

Answer:

the function is EVEN because f(x)= f(-x)

Step-by-step explanation:

Key to find if a function f(x) is even or odd is to replace the x with -x

if the results comes out to be f(x) then it is even function

if the results comes out to be -f(x) then it is odd function

where as graphically even f(x) will be symmetric around the y-axis and odd f(x) will be symmetric around the origin.

In given case f(x)=7

if we replace x with -x in above equation then results is 7

f(-x)= 7

hence f(x)= f(-x) = 7

540 = a/11

5940 = x

Answer: x = 5940

Answer: [tex]a=5,940[/tex]

Step-by-step explanation:

Given the equation [tex]540=\frac{a}{11}[/tex], you need to find the value of "a", then, you need to solve for "a".

You need to apply the Multiplication property of equality, which establishes that:

[tex]If\ a=b,\ then\ a*c=b*c[/tex]

Therefore, based on this property, you can multiply both sides of the equation by 11.

Then, you get the following solution:

[tex](11)(540)=(\frac{a}{11})(11)\\\\a=5,940[/tex]

ANSWER

The correct choice is C.

EXPLANATION

We know that:

[tex] \sqrt[3]{7} = {7}^{ \frac{1}{3} } [/tex]

We want to simplify:

[tex]( { {7}^{ \frac{1}{3} } )}^{3} [/tex]

The exponent here is 3. This means that the base must multiply itself 3 times.

[tex] ( { {7}^{ \frac{1}{3} } )}^{3} = {7}^{ \frac{1}{3} } \times {7}^{ \frac{1}{3} } \times {7}^{ \frac{1}{3} } [/tex]

Recall that:

[tex] {a}^{m} \times {a}^{n} = {a}^{m + n} [/tex]

This implies that,

[tex] ( { {7}^{ \frac{1}{3} } )}^{3} = {7}^{ \frac{1}{3} + \frac{1}{3} + \frac{1}{3} } [/tex]

Simplify:

[tex] ( { {7}^{ \frac{1}{3} } )}^{3} = {7}^{ \frac{3}{3}} [/tex]

[tex]( { {7}^{ \frac{1}{3} } )}^{3} = {7}^{ 1} = 7[/tex]

The correct choice is C

[tex] < \: - 3, -2 \: > [/tex]

EXPLANATION

The given vectors are:

[tex]u = < \: - 3,5 \: > [/tex]

and

[tex]v= < \: 6, - 3\: > [/tex]

[tex] - u - v = - 1< \: - 3,5 \: > -1 < \: 6, - 3\: > [/tex]

Use the scalar to multiply and obtain;

[tex] - u - v = < \: 3, - 5 \: > + < \: - 6, 3\: > [/tex]

Simplify to get:

[tex]- u - v = < \: 3 - 6, - 5 + 3 \: > [/tex]

[tex]- u - v = < \: - 3, -2 \: > [/tex]

To find the component form of -u - v, subtract the x-components and y-components separately. The x-component is 3, and the y-component is -2.

The component form of -u - v can be found by subtracting the x-components and the y-components of u and v separately. Given that u=(-3,5) and v =(6,-3), the x-component of -u - v is -(-3) - 6 = -3 + 6 = 3, and the y-component is -(5) - (-3) = -5 + 3 = -2.

Step-by-step explanation:

Given function is [tex]f\left(x\right)=-2\sqrt{x-3}+8[/tex].

Now let's find it's range.

we know that square root function always gives positive output then:

[tex]\sqrt{x-3}\ge0[/tex]

[tex]-2\sqrt{x-3}\le-2\left(0\right)[/tex]

[tex]-2\sqrt{x-3}\le0[/tex]

[tex]-2\sqrt{x-3}+8\le0+8[/tex]

[tex]-2\sqrt{x-3}+8\le 8[/tex]

[tex]f(x) \le 8[/tex]

Hence range of the function is [tex](-\infty,8][/tex].

we can repeat same process to find the range of all the given choices.

we will find that only 3rd choice has same range.

Hence final answer is [tex]g\left(x\right)=-\sqrt{x+3}+8[/tex]

Answer:

Option D. $119.25

Step-by-step explanation:

Today's stock listing for Parchar Special Effects shown below.

52 wk high  =  160.44

52 wk low   =   81.91

Symbol        =  PCR

Div.              = 7.55

Close           =  114.36

Net change = -4.89

Based on this information today's close is $114.36 and Net change is -4.89. It means the value of yesterday was 4.89 more than today's close.

Therefore, yesterday's price = 114.36 + 4.89 = $119.25

Yesterday's price was $119.25.

Answer:

Final answer is $7.52.

Step-by-step explanation:

Given that initial amount P = $2000

Interest rate r = 4.6% = 0.046

Number of compounding periods per year = n = 2 {semiannually}

Time = 2 years

Then future value is given by :

[tex]A=P\left(1+\frac{r}{n}\right)^{n\left(t\right)}[/tex]

[tex]A=2000\left(1+\frac{0.046}{2}\right)^{2\left(2\right)}=2190.45[/tex]

Similarly calculate future value for 2nd case:

Given that initial amount P = $2000

Interest rate r = 4.4% = 0.044

Number of compounding periods per year = n = 4 {quarterly}

Time = 2 years

Then future value is given by :

[tex]A=P\left(1+\frac{r}{n}\right)^{n\left(t\right)}[/tex]

[tex]A=2000\left(1+\frac{0.044}{4}\right)^{4\left(2\right)}=2182.93[/tex]

then difference = 2190.45 - 2182.93 = 7.52

Hence final answer is $7.52.

9! = 362880

Answer:

362,880

9! is also know as 9x all the numbers lower then it, so it would be 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1.

Answer:

b = 8sqrt(3)

Step-by-step explanation:

The triangle has a 30-deg angle and a right angle, so the third angle measures 60 degrees making this a 30-60-90 degree right triangle.

You don't mention which method to use to solve the problem.

You can use trigonometry ratios or the ratios of the lenghts of the sides of a 30-60-90 triangle

I'll use the second method.

In a 30-60-90 triangle, the lengths of the sides are in the ratio:

1 : sqrt(3) : 2

The long leg measures 12 and corresponds to sqrt(3) in the ratio, so we can find the length of the short leg by dividing 12 by sqrt(3).

12/sqrt(3) = [4 * sqrt(3) * sqrt(3)]/sqrt(3) = 4sqrt(3)

The hypotenuse is twice the length of the short leg.

b = 2 * 4sqrt(3) = 8sqrt(3)

The value of b is 8√3 because cos is the ratio of side adjacent to the angle to side opposite to the angle.

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

We have a right angle triangle shown in the picture.

From the cos ratio:

cos30 = 12/b

b = 12/cos30

b = 12/(√3/2)

After factorization:

b = (24√3)/3

b = 8√3

Thus, the value of b is 8√3 because cos is the ratio of side adjacent to the angle to side opposite to the angle.
