What Values of X will make x2 (Exponent of 2) =16 true? HELPPPPPP!!
A)4 AND -4
B)2
C)4
D)6 AND -6

Answers

Answer 1

Answer:

A

Step-by-step explanation:

Given

x² = 16 ( take the square root of both sides )

[tex]\sqrt{x^2}[/tex] = ± [tex]\sqrt{16}[/tex] ← note plus or minus sign

x = ± 4

Since 4² = 4 × 4 = 16 and

(- 4)² = - 4 × - 4 = 16

Answer:

D; D; B

Step-by-step explanation:

Question 1:

All of the outcomes are not equally likely because there is a lot of variation between the relative frequencies of the different landing positions.

As we can see from the data, the cup will most likely land sideways, then backwards, then upright. Since there is a lot of variation between the number of times this happens, we know this isn't just because of the random factor, but because there is a higher probability of it landing on its side. Additionally, the huge differences between the numbers tell us that the 3 outcomes are not equally likely. That removes option A and B. We know it isn't option C because the relative frequency of it landing sideways is not the lowest, but the highest. (Upwards: 9/60= 0.15= 15%, Upside down: 15/60= 0.25= 25%, Sideways: 36/60= 0.6= 60%) Therefore, option D is the correct answer.

Question 2:

Yes, it is a fair model because the relative frequencies of all the outcomes are similar.

We can look at the table, and understand the the relative frequencies of these outcomes will all be similar.

We can calculate it to make sure.

L: 10/40= 0.25= 25%

E: 11/40= 0.275= 27.5%

A: 9/40= 0.225= 22.5%

P: 10/40= 0.25= 25%

As you can see, the relative frequency of all these options is similar, indicating that this is a fair model.

Question 3:

Yes, it is a fair model because the relative frequencies of all the outcomes are similar.

Once again, when looking at the tables, we see that all outcomes occur a similar number of times, meaning that the model is most likely fair.

To make sure, we can calculate the relative frequencies.

Green: 12/50= 0.24= 24%

Pink: 9/50= 0.18= 18%

Yellow: 11/50= 0.22= 22%

Blue: 10/50= 0.2= 20%

Red: 8/50= 0.16= 16%

Although these frequencies aren't as similar as the previous model, I would still deem them similar enough for the model to be considered fair.

If the APR of a savings account is 4.8% and interest is compounded monthly,

what is the approximate APY of the account?

O A. 1.05%

O B. 10.49%

O C. 4.91%

O D. 4%

Answers

Answer:

  C.  4.91%

Step-by-step explanation:

The effect of frequent compounding is to increase the nominal interest rate by a small factor. For interest rates in a practical range (<20%/year), the effective increase in rate will be approximately half the original interest rate.

Approximation

For an interest rate of 4.8%, we expect the compounding to increase it by less than 2.4%. The maximum effective rate due to compounding is approximately (4.8%)(1 +2.4%) ≈ 4.91%.

Exact computation

For nominal annual rate r compounded n times per year, the effective annual rate is ...

  r' = (1 +r/n)^n -1

For r = 0.048 and n = 12, this becomes ...

  r' = (1 +0.048/12)^12 -1 = 1.004^12 -1 ≈ 1.049070208 -1 ≈ 4.91%

__

Additional comment

After you have worked with interest compounding for a bit, you realize compounding increases the effective rate by a small amount. That means the value will be more than 4.8% (eliminating choices A and D), but certainly will not be as high as 10% (eliminating choice B). The only reasonable choice is C, which happens to be the correct one.

a. What will be the area of the

b. Will the area of the new garden be
twice as large as it is now? Explain.

Answers

a. If you double both sides, you'll get a rectangle with dimensions 20 feet wide and 30 feet long, therefore the area will be 20 × 30 = 600 feet².

b. The area of the old rectangle was 10 × 15 = 150 feet², so no the area is not twice as large, it is 4 times as large. This is because if the area is base × height, then doubling both of these gets you (2 × base) × (2 × height) = 4 × (base × height).

x² - 9x + 8 = 0

x² - 8x - x + 8 = 0

x(x - 8) - (x -8) = 0

(x - 8)(x - 1) = 0

x = 1, x = 8

Answer:

x=8     x=1

Step-by-step explanation:

f(x) = g(x)

6x^2 -5x +10 = 5x^2 +4x+2

Subtract 5x^2 from each side

6x^2-5x^2 -5x +10 = 5x^2-5x^2 +4x+2

x^2 -5x +10 = 4x+2

Subtract 4x from each side

x^2 -5x-4x +10 = 4x-4x+2

x^2 -9x +10 = 2

Subtract 2 from each side

x^2 -9x +10-2 = 2-2

Answers

Answer:

12,6

Step-by-step explanation:

The factor pair of 72 is 12 and 6 because, factors are the 2 numbers you multiply together to get the product. In this case, the product is 72. 12x6=72 So therefore, 12 and 6 are the factors of 72. You can figure this out simply by multiplying 12 and 6 together.

Final answer:

The factor pairs of 72 are (1,72), (2,36), (3,24), (4,18), and (6,12).

Explanation:

To find the factor pairs of 72, we need to find pairs of numbers that multiply together to give us 72. Let's list all the factors of 72 and check which pairs multiply to give us 72:

1 x 72 = 722 x 36 = 723 x 24 = 724 x 18 = 726 x 12 = 72

So, the factor pairs of 72 are (1, 72), (2, 36), (3, 24), (4, 18), and (6, 12).

Fatima opens an account with 1300 that earns 3.5% interest, compounded monthly. How long will it take the account value to be $2500?

Answers

Answer:

The formula to calculate the account value in future (compounded monthly):

A = Principal x (1 + rate/12)^(month)

=> 2500 = 1300 x (1 + (3.5/100)/12)^(month)

=> (1 + 0.00291)^(month) = 2500/1300

=> 1.00291^(month) = 1.923

=> month = log(1.923)/log(1.00291) = 225

=> It will take 225 months to have 2500 dollar in account.

An above-ground rainwater tank is rectangular and has a length of 15

feet and a height of 2 feet. It will hold 375 cubic feet of water. What is the

height of the rainwater tank?

Answers

Answer:

The width of the tank is 12.5 feet

Step-by-step explanation:

We need to find the width, not height of the rainwater tank, since the height is already given.

The volume of a rectangular prism is given as:

V = L * W * H

where L = length of the tank

W = width of tank

H = height of tank

We have its volume as 375 cubic feet and the length, L, as 15 feet and height, H, as 2 feet.

Therefore, its width is:

375 = 15 * W * 2

375 = 30W

=> W = 375 / 30

W = 12.5 feet

The width of the tank is 12.5 feet.

3 parts: List the ratios for using angle A as the angle of reference reduce when necessary

Sin A= Cos A= Tan A=

Answers

Answer:

[tex]\sin{A}=21/29\\\cos{A}=20/29\\\tan{A}=21/20[/tex]

Step-by-step explanation:

The sine of an angle in a right triangle is the ratio of the side across from the angle with the hypotenuse of the triangle (the hypotenuse is the side across from the right angle). In this case, the sine of angle A, shortened to [tex]\sin{A}[/tex], is [tex]21/29[/tex].

Cosine is short for "complementary sine." If the angles A + C = 90, the cosine of A is equal to the sine of C, since A and C are complementary. So [tex]\cos{A}=\sin{C}=20/29[/tex]. Notice that this ratio is the same as the ratio of the side adjacent to angle A (AB), to the hypotenuse.

The tangent is the ratio of the side opposite an angle to the side adjacent to it. Here, [tex]\tan{A}=21/20[/tex]. So, our trig ratios for this angle are

[tex]\sin{A}=21/29\\\cos{A}=20/29\\\tan{A}=21/20[/tex]

The gas tank in Feliz's car is full. Each time he drives to or from work, he uses 1 of a full
tank of gas. Which equation represents the number of times Feliz can drive to or from work
with the gas in his tank?

Answers

Answer: number of times feliz can drive to or from work with the gas in his tank is 10 times

Step-by-step explanation:

Let's start by reviewing the slope-intercept formula:

y = mx + b

At the start of the journey, we have a tank that's 5/6 full and have yet to go anywhere. That means that our b is 5/6.

Thus:

y = mx + 5/6

Now, every time he drives to or from work, be loses 1/12 of a full tank.

Thus;

y = -(1/12)x + 5/6

negative because the initial volume of gas is decreasing whenever he goes out.

Now, to get the number of times feliz can drive to or from work with the gas in his tank, y = 0.

Thus,

0 = -(1/12)x + 5/6

Add (1/12)x to both sides to give;

(1/12)x = 5/6

x = 5/6 ÷ 1/12

x = 10

Now, the "C" in ₄C₂ is short for "combinations." Order doesn't matter where combinations are concerned. Let's say the set we're choosing from is the set of the letters A, B, C, and D. Here are all the ways we can choose two different letters from that list:

AB, AC, AD, BA, BC, BD, CA, CB, CD, DA, DB, DC

Notice that, for each pair, we have another in the set that contains the same letters: AB and BA, AC and CA, BD and DB... If order doesn't matter, we can cut all of those second pairs, giving us 12 / 2  = 6 total combinations.

You require space to service 65 vehicles at any one time. Will a facility measuring 165 ft. by 130 ft. be adequate if each vehicle requires 300 sq.ft.?

Answers

Answer:

Step-by-step explanation:

You require space to service 65 vehicles at any one time and each vehicle requires 300 ft² of space. This means, the 65 vehicles will require space of:

65 * 300 = 19500 ft²

A facility measuring 165 ft. by 130 ft is being considered. The area of the facility is:
