According to her running log, Ariana averaged 4 miles per week last month and 75% less this month. How much did she average this month?

The answer is = 1 + sin x

Explanation

we need

a^2 - b^2 = (a+b) (a-b)

we use

cos^2 x + sin^2 x = 1

cos^2 x = 1 - sin^2 x = ( 1 + sin x) ( 1 - sin x )

therefore

cos ^2 x over 1 - sin x = 1+ sin x

10 year: $1000000

20 years: $2000000

Answer:

10 years = 8,900.00.

20 years = 23,200.00.

Step-by-step explanation:

Hey, let me tell you how to solve this; I had trouble as well.

Since the policy is worth 100,000, you divide this by 1,000.

That gives us 100.

Now, multiply 100 by the 10 yr cash value, which is 89.

That results in 8,900.00.

Taking 100 again, multiply it by the 20 yr cash value, 232.

That gives us 23,200.00.

Hope it helps.

Garden is in the shape of triangle.

[tex]Area of garden = \dfrac{1}{2}bh = \dfrac{1}{2}*10*6 = 5 *3 = 15 \ m^{2}[/tex]

Drive way:

length = 4 + 10 = 14m

Width = 3 m

Area  = length * width = 14 * 3 = 42 sq.m

Perimeter of the property:

Length = 14 m

Width = 3 + 9 + 6 = 18 m

Perimeter = 2*(length + width) = 2*(14 + 18) = 2 * 32 = 64 m

The amount of interest paid per year is $2400

What is Interest rate?

An interest rate is the percentage a lender charges on the amount of money borrowed from them.

Given that, Brendon Walsh wants to borrow the sum of $40,000 from the bank

Interest rate is 6%

Time is 5 years

Therefore, the yearly payment amount can be calculated as follows

= 40,000 × 5 × 6/100

= 40,000 × 5 × 0.06

= 12000/5

= $2,400

Hence, the yearly payment is $2,400

The number of strawberry ice cream cones the shop sells that Saturday is 9 ice cream.

calculation:-

An ice cream shop sells ice cream cones with exactly 1 of 3 ice cream flavors in the cone.

let a number of strawberry ice cream this shop sold on satrday=X

  number of vanilla ice cream shops sold = X+2

       number of Chocolate ice cream shops sold = X+2+11

Total number of icecream sold on Saturday =42

       ⇒ X+ X+2+ X+2+11 = 42

      ⇒ 3X + 15 =42

The percentage sales tax is 8%.

The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).

Given,

The total cost after sales tax to fix Azar’s computer is represented by the expression:

- 0.08 (55h) + 55h

where h represents the number of hours it takes to fix Azar’s computer.

We need to find out what percentage of sales tax is Azar being charged.

and what part of the expression represents the dollar amount of sales tax Azar must pay.

It is mostly represented by a percentage.

We have,

100% = 100/100 = 1

50% = 50/100 = 1/2 = 0.5

25% = 25/100 = 1/4 = 0.25

20% = 20/100 = 1/5 = 0.2

We have,

- 0.08 (55h) + 55h

The sales tax is also charged according to the number of hours so,

In the expression 0.08 can be written as a percentage.

0.08 = 8 /100 = 8%

The percentage sales tax is 8%.

Now,

0.08 55(h) means the sales tax Azar must pay.

For 1 hour,

0.08 x 55 = 4.4 is the sales tax.

For 2 hours,

0.08 x (55x2) = 0.08 x 110 = 8.8.

And so on,

So,

The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).

Thus,

The percentage sales tax is 8%.

The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).

Answer:

Step-by-step explanation:

6) Area of rectangle = 78.5 sq . cm

length * width = 78.5

15.7 * width = 78.5

        Width = 78.5/15.7

                  = 5 cm

7) circumference of circle = 44 cm

[tex]2\pi r = 44 \\\\2*\dfrac{22}{7}*r=44\\\\r = 44*\dfrac{7}{2*22}\\\\r = 7[/tex]

r = 7 cm

Explanation:

The slope of any vertical line is always undefined. This is because [tex]\text{slope} = \frac{\text{rise}}{\text{run}}[/tex], and the "run" portion is 0. The run represents the change in x, but we don't have a change in x for vertical lines. The x value is always some constant.

So this is why the run is 0, and it leads to a division by zero error, causing an undefined slope.

Answer:

I'll assume "position 7" refers to distance and not to the order of other people.  

Step-by-step explanation:

We want an equation of the form y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).  We can assume that "claps" is a new measure of distance.  0 claps is the finish.

Let's express the information provided in point format.

"At 2 claps, Joe is in position 7"  is (2,7)  2 is the distance (claps) and 7 is the time (minutes)

And we can say the rate is also the slope of a line.  "rate of 3 claps per minute" is 3c/m, where c is claps and m is minutes.

We can start a line equation by stating y = 3x + b, where we're using the rate, 3 c/m, as the slope, m.

We need to determine the value of b.  We can use the given point (2,7) and solve for m:

y = 3x + b

7 = 3*(2) + b

b = 1

The equation becomes y = 3x + 1

y is the distance in claps and x is the time in minutes.

At a time of 2 claps he is at position of 7.  b = 1 means he started 1 clap further from the finish at 0 claps.

To find the time required to reach the finish, we need to know the total distance, in claps.

Answer:

m^2/n

Step-by-step explanation:

The following laws of exponent are useful to this problem:

[tex] \displaystyle \large{ {(mn)}^{b} = {m}^{b} {n}^{b} } \\ \displaystyle \large{ {n}^{ - b} = \frac{1}{ {n}^{b} } }[/tex]

We are given the expression:

[tex] \displaystyle \large{( {m}^{8} {n}^{ - 4} )^{ \frac{1}{4} } }[/tex]

Use the first law of exponent above.

[tex] \displaystyle \large{( {m}^{8} {n}^{ - 4} )^{ \frac{1}{4} } = {m}^{(8)( \frac{1}{4}) } {n}^{ ( - 4)( \frac{1}{4}) } } \\ \displaystyle \large{( {m}^{8} {n}^{ - 4} )^{ \frac{1}{4} } = {m}^{2 } {n}^{ - 1} }[/tex]

Make sure to recall the important necesscary fundamental math such as operation with negative numbers/integers, basic division, fraction, etc.

From the expression, apply the second law of exponent to n^-1.

[tex] \displaystyle \large{( {m}^{8} {n}^{ - 4} )^{ \frac{1}{4} } = {m}^{2 } ( \frac{1}{ {n}^{1} } )} \\ \displaystyle \large{( {m}^{8} {n}^{ - 4} )^{ \frac{1}{4} } = {m}^{2 } ( \frac{1}{ {n} } )} \\ [/tex]

Multiply m in.

[tex] \displaystyle \large{( {m}^{8} {n}^{ - 4} )^{ \frac{1}{4} } = \frac{ {m}^{2} }{ {n} } }[/tex]

Thus the answer is m^2/n.

Step-by-step explanation:

1) f(x)=1/3(x+1)^2

so if we use the equation f(x)=a(x-h)^2+k then we can plug in the different things.  a would represent the compress/stretches, so in order to move horizontally, we would need to do 1/3

for h: that is the horizontal translations so, left and right. BUT remember it's the opposite. so if you want to go left <-- you would have to put a + sign and to go right you would have to put a - sign.
