Answer:

  B.  F(x) = 2(x -4)² +4

Step-by-step explanation:

The graph opens upward, so has a positive leading coefficient. (Eliminates choices A and C.)

The graph is translated right 4 units, so x in x² has been replaced by (x-4). (Eliminates choice D.)

The transformed graph is of the equation ...

  F(x) = 2(x -4)² +4

John and rachel share £2400 prize money at a ratio of 2:4. How much do they each get?
Stels [109]

Answer: John:£800

Rachel:£1600


Step-by-step explanation:

Since John and Rachel shared £2400 in the ratio 2:4, it means that £2400 was equal to(2+4) units, which is 6 units.

Thus, each unit is £2400/6= £400

Hence, John got £400x2=£800, and Rachel got £400x4=1600.

Hope u understand my solution. :)

A triangle has sides with lengths of 6 inches, 13 inches, and 17 inches. Is it a right triangle?
Tems11 [23]

Answer:

Nope

Step-by-step explanation:

To now if a triangle is a right angle, use Pythagoras Theorem,

a^2 + b^2 = c^2

C usually be the longest side of the triangle, C = 17

Then also let a and b be 6 and 13 respectively.

6^2 + 13^2 =205

C^2 = 205

C = sqrt(205) = 14.32

therefore no this is not a right angle triangle

A veterinarian does research on the causes of enteroliths, stones that develop in the colon of horses. She suspects that feeding
dsp73

Answer:

On average, horses with and without enteroliths are fed the same amount of alfalfa per month

Step-by-step explanation:

Hello!

The veterinarian wants to research if eating alfalfa causes horses to have enteroliths.

The study variables are:

X₁: number of alfalfa flakes eaten over a month by a horse with enteroliths.

X₂: number of alfalfa flakes eaten over a month by a horse free of enteroliths.

She calculated a CI interval, with level 1 - α and the interval contained the cero.

With a significance level α, the hypotheses are:

H₀: μ₁ - μ₂ = 0

H₁: μ₁ - μ₂ ≠ 0

To decide whether you should reject or not the null hypothesis using a Confidence Interval is the following:

If the CI contains the number stated in the null hypothesis, the decision is to not reject the null hypothesis.

If the CI doesn't contain the number stated in the null hypothesis, then the decision is to reject the null hypothesis.

Since the interval contains the cero, if 1 - α and α are complementary, the decision is to reject the null hypothesis.

This means that at a level of significance of α, you can conclude that there is no difference between the population means of the numbers of alfalfa flakes eaten by horses with or without enteroliths.

I hope it helps!
