Write an equation for the sine wave. What is the amplitude and period?

Answers

Answer:

Amplitude is the distance between the center line of the function and the top or bottom of the function, and the period is the distance between two peaks of the graph, or the distance it takes for the entire graph to repeat. Using this equation: Amplitude =APeriod =2πBHorizontal shift to the left =CVertical shift =D.

A group of 25 people are going to run a race. The top 8 finishers advance to the finals. Determine the number of possible outcomes.

Answers

Answer:

n[total]=25

n[top finishers]=8

the number of possible outcome

=[tex] \frac{25 \times 24 \times 23 \times 22 \times 21 \times 20 \times 19 \times 18}{8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1} = 1081575[/tex]outcomes

Answer:

[tex] \large\boxed{ \boxed{\rm 1081575 \: outcomes}}[/tex]

Step-by-step explanation:

to determine the number of possible outcomes we can consider Combination given by

[tex] \displaystyle \binom{n}{r} = \frac{n!}{r!(n - r)!} [/tex]

where:

n is the total number of objects in the setr is the number of choosing objects from the set

so let n and r be 25 and 8 respectively thus

substitute:

[tex] \displaystyle \binom{25}{8} = \frac{25!}{8!(25- 8)!} [/tex]

simplify parentheses:

[tex] \displaystyle \binom{25}{8} = \frac{25!}{8! \times 17!} [/tex]

rewrite numeratorr:

[tex] \rm \displaystyle \binom{25}{8} = \frac{25 \times 24 \times 23 \times 22 \times 21 \times 20 \times 19 \times 18 \times 17!}{8! \times 17!} [/tex]

reduce fraction:

[tex]\rm \displaystyle \binom{25}{8} = \frac{25 \times 24 \times 23 \times 22 \times 21 \times 20 \times 19 \times 18 }{8! } [/tex]

simplify numerator and denominator:

[tex]\rm \displaystyle \binom{25}{8} = \frac{43609104000}{40320 } [/tex]

simplify division:

[tex]\rm \displaystyle \binom{25}{8} = 1081575[/tex]

hence,

the number of outcomes is 1081575

Answer:   200(4t2−4t+3)

Step-by-step explanation:

Factor 800t^2−800t+600

800t^2−800t+600

=200(4t2−4t+3)

Answer:

Hello Kaydie! Assuming you're trying to factor this, the correct answer is [tex]200\left(4t^2-4t+3\right)[/tex].

Step-by-step explanation:

Since 800 and 600 both can't be taken perfect squares, that means taking out the greatest common factor is the best way to start. 200 is the greatest common factor of all three terms, so take 200 out and write it as 200 multiplying the terms in a parenthesis, which would be [tex]200\left(4t^2-4t+3\right)[/tex]. Since [tex]4t^2-4t+3[/tex] cannot be simplified any further, that means your answer should be [tex]200\left(4t^2-4t+3\right)[/tex]. Be sure to tell me if factoring the expression was not what the question asked for, and I'll edit my answer. Have a good day!

Huy is painting eight styrofoam cubes for a science project. the side length of the cube measures 6 1/2 inches. What is the total surface area that Huy will paint

Answers

Answer:

2028 square inches

Step-by-step explanation:

The side length of the styrofoam cube measures 6 1/2 inches.

Step 1

We find the surface area of a cube

The formula is given as

Surface Area = 6a²

Where a = Side length of the cube = 6 1/2 inches

Hence,

Surface area of a cube = 6 × (6 1/2inches)²

= 253.5 square inches

Step 2

Huy is painting eight styrofoam cubes for a science project.

The total surface area that Huy will paint is calculated as:

1 styrofoam cube = 253.5 square inches

8 styrofoam cubes = x

Cross Mulitiply

x = 8 × 253.5 square inches

x = 2028 square inches

Therefore, the total surface area that Huy will paint is 2028 square inches.

Answers

Answer:

The value of [tex]c[/tex] must be 3.

Step-by-step explanation:

Let be [tex]y = f(x)[/tex], there is an horizontal translation when function is transformed into [tex]y = f(x-c)[/tex], where:

[tex]c > 0[/tex] - Shift to the right.

[tex]c < 0[/tex] - Shift to the left.

Sara’s hair was 25 inches long. Three years later it was 43 inches long. What was the percent increase rounded to the nearest hundredth

Answers

Answer:

Increase Percentage =

                               [tex]\frac{increase}{original} * 100= \frac{43-25}{25} *100= \frac{18}{25}*100 = 72[/tex]

Percentage increase in hairlength = 72%

The percent increase rounded to the nearest hundredth will be 72.

How do you calculate the percentage of a total value?

Since percent implies 100, we will split the total portion into 100 parts and then multiply it by b to gather b things per 100 items.

The percentage increase is found as;

[tex]\rm \% increase= \frac{Change\ in\ value }{original \ value } \\\\ \rm \% increase= \frac{13-25}{25} \times 100 \\\\ \% increase= 72[/tex]

Stella has some colored cards that are the same size and shape. • The probability of randomly selecting a blue card is 20%. • The probability of randomly selecting a red card is 30%. What is the probability Stella will randomly select a card that is NOT blue, replace it, then randomly select a card that is red? Helpppp

Answers

Answer: 0.24

Step-by-step explanation:

The probability of randomly selecting a blue card = 20% = 0.2

The probability of randomly selecting a red card = 30% = 0.3

The probability of not randomly selecting a blue card = 1 - 0.2 = 0.8

The probability of not randomly selecting a red card = 1 - 0.3 = 0.7

Therefore, the probability that Stella will randomly select a card that is not blue, replace it, then randomly select a card that is red will be:

= P(not blue ) × P(red)

= 0.8 × 0.3

= 0.24

The answer is 0.24
