Factor the expression y2+6y-16

Mathematics
2 answers:
Arisa [49]3 years ago
8 0

Step 1 ) Break up the expression.

\displaystyle\ y^{2} + 6y -16

\displaystyle\ (y^{2} -2y) + (8y -16)

Step 2 ) Factor y from y^{2} - 2y.

\displaystyle\ (y^{2} -2y) + (8y -16)

\displaystyle\ y ( y - 2 )

Step 3 ) Factor 8 from 8y - 16

\displaystyle\ (y^{2} -2y) + (8y -16)

\displaystyle\ 8 ( y - 2)

Step 4 ) Place new factors in group.

\displaystyle\ y ( y - 2 )

\displaystyle\ 8 ( y - 2)

\displaystyle\ y(y-2)+8(y-2)

Step 5 ) Distribute.

\displaystyle\ y(y-2)+8(y-2)

\displaystyle\ (y-2) + 8(y-2)

\displaystyle\ (y-2) (y+8)

The expression factored is...

\framebox {=(y-2)(y+8)}

y^2+6y-16=y^2+8y-2y-16=y(y+8)-2(y+8)=(y+8)(y-2)

A 25 ft. ladder resting against the side of a building forms a right triangle with the ground. The bottom of the ladder is 7 ft.
ruslelena [56]

Answer:

The correct answer is 24

Step-by-step explanation:

to solve this you will need to use the pathagreom theorum

a^{2}+b^{2}=c^{2}

A= one side lenth

B= the secons side lenth

C= hypotnuse

It is helpfull to draw out the situation

you know that the latter is 25 ft, that is your hypotnuse

you also know that the 7 ft away from the base of the building is one of the side lenths, lets call it side a

so plug the numbers into the equation

7^2 + b^2 = 25 ^2

you leave b^2 alone because that is the side you are trying to find

now square 7 and 25 but leave b^2 alone

49 + b^2 = 625

now subtract 49 from both sides

b^2 = 576

now to get rid of the square of b you have to do the opposite and square root both sides removing the square of the B and giving you the answer of..........

B= 24

Hope this helped!! I tryed to explain it as simpil as possiable

Can someone help me with this f(g(x))=2(3x-4)^2+5?
Greeley [361]

Answer:

f(x)=349525

Step-by-step explanation:

f(x)=2(3x-4)^2+5

f(x)= 6x - 8^7

f(x)= 6x - 2,097,152

f(-6x)= - 2,097,152

/-6x       /-6x

f(x)=349525


I hope I am not terribly wrong but I probably am good luck

Which statistic is a measure of how data are dispersed in a population and can be used to give context to larger data sets
OLEGan [10]

Answer:

standard deviation

Step-by-step explanation:

The standard deviation is defined as the measure of how spread out the numbers are in a given population. In other words, statistics refers to the amount of the dispersion or variation of a set of given values.

It is denoted by the Greek letter sigma, σ.

Thus the standard deviation is the measure of how dispersed the data are in the population which can be used to provide context to a larger data sets.

The surface area of a sphere is 576pi square units. Which choice represents the volume of the sphere?
Leona [35]

Answer:

\large\boxed{V=2304\pi}

Step-by-step explanation:

The formula of a surface area of a sphere:

S.A.=4\pi R^2

R - radius

We have

S.A.=576\pi

Substitute and solve for R:

4\pi R^2=576\pi         <em>divide both sides by π</em>

4R^2=576          <em>divide both sides by 4</em>

R^2=144\to R=\sqrt{144}\\\\R=12

The formula of a volume of a sphere:

V+\dfrac{4}{3}\pi R^3

Substitute:

V=\dfrac{4}{3}\pi(12^3)=\dfrac{4}{3}\pi(1728)=(4)\pi(576)=2304\pi
