<u>Answer:</u>

y = 5x (x+2)

<u>Step-by-step explanation:</u>

We are given the following the quadratic function and we are to rewrite it in intercept or factored form:

$y = 5x^2 + 10x$

We can factorize the given expression so taking the common factors out of it to get:

$y=5x^2 + 10x$

$y = 5x (x + 2)$

Therefore, the factored form of the given quadratic function is y = 5x (x+2).

Answer:

y = 5x(x+2)

Step-by-step explanation:

Given quadratic equation is:

y = 5x²+10x

We have to transform given function into factored form.

Taking x common from given function,we get

y = x(5x+10)

5 and 10 are multiple of 5.

Hence,

taking 5 as common,we get

y = x(5)(x+2)

y = 5x(x+2) is factored form of given quadratic function.

How much should you invest at 3.7% simple interest in order to earn $70 interest in 11 months?

valkas [14]

Step-by-step explanation:

in this condition we are given simple interest time and rate

so principal is missing so we should use the formula of principal that is

P=I×100/T×R

but we should convert that month in to years and we convert it by dividing it by 12.

BRAINLIEST, 5 STARS & THANKS IF ANSWERED CORRECTLY

trapecia [35]

Answer:

Step-by-step explanation:

This is an arithmetic sequence with a₁ (first term) = 10.5 and d (common difference) = 11 - 10.5 = 0.5

Explicit formula for arithmetic sequences: aₙ = a₁ + (n - 1) * d

Therefore, aₙ = 10.5 + (n - 1) * 0.5 = 0.5n + 10 so a₂₂ = 0.5 * 22 + 10 = 21.

Pllssss help 7th grade math

MrRa [10]

For this one you have to add all of the numbers. 5.5 plus 6.5 plus 4.5 plus 2.75 which equals to 19.25. Then you, 19.25/4=4.8125. All i did was turn the fractions into decimals to make it easier and do the math.

Anarel [89]

Ok if there is 423 dogs and 56 big dogs need to sub the dogs and you get
423-56=357 big dogs

SO there are 357 dig dogs

Based on the cumulative frequency histogram, determine the number of swimmers who swam between 200 and 249 yards. Determine the

Lostsunrise [7]

Answer:

$(a)\ 200 \to 249 =3$

$(b)\ 150 \to 199 = 0$

$(c)\ Total = 20$

Step-by-step explanation:

Given

See attachment for cumulative frequency histogram

Solving (a): Swimmers between 200yd and 249yd

To do this, we simply read the data from the 0 mark

From the histogram, we have:

$0 \to 249 = 15$

and

$0 \to 199 = 12$

So:

$200 \to 249 = 0 \to 249 - 0 \to 199$

This gives:

$200 \to 249 = 15-12$

$200 \to 249 =3$

Solving (b): Swimmers between 150yd and 199yd

To do this, we simply read the data from the 0 mark

From the histogram, we have:

$0 \to 149 = 12$

and

$0 \to 199 = 12$

So:

$150 \to 199 = 0 \to 199 - 0 \to 149$

This gives:

$150 \to 199 = 12-12$

$150 \to 199 = 0$

Solving (c): Total swimmers

To do this, we simply read the longest bar of the histogram

$Longest = 20$

Hence:

$Total = 20$
