Answer:

vertex = (- 10, - 10 )

Step-by-step explanation:

The equation of a quadratic in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

To obtain this form use the method of completing the square.

Given

h(x) = x² + 20x + 90

add/subtract ( half the coefficient of the x- term )²

h(x) = x² + 2(10)x + 100 - 100 + 90

      = (x + 10)² - 10 ← in vertex form

with (h, k ) = (- 10, - 10 )

(4,2) (8,2) points are separated by a distance of 4 units.

The 2D distance formula gives the shortest distance between two points in a two-dimensional plane.

Distance Formula =  [tex]\sqrt{(x_{2} -x_{1} )^{2} +(y_{2}-y_{1} )^{2} }[/tex]

Given

Distance of 4 units

Option A:

[tex](x_{1} ,y_{1})=(7,7)[/tex]

[tex](x_{2} ,y_{2})=(1,7)[/tex]

Distance = [tex]\sqrt{(x_{2} -x_{1} )^{2} +(y_{2}-y_{1} )^{2} }[/tex]

= [tex]\sqrt{(1-7)^{2}+(7-7)^{2} } =6[/tex]

Option B:

[tex](x_{1} ,y_{1})=(3,3)[/tex]

[tex](x_{2} ,y_{2})=(1,3)[/tex]

Distance = [tex]\sqrt{(x_{2} -x_{1} )^{2} +(y_{2}-y_{1} )^{2} }[/tex]

= [tex]\sqrt{(1-3)^{2}+(3-3)^{2} } =2[/tex]

Option C:

[tex](x_{1} ,y_{1})=(4,2)[/tex]

[tex](x_{2} ,y_{2})=(8,2)[/tex]

Distance = [tex]\sqrt{(x_{2} -x_{1} )^{2} +(y_{2}-y_{1} )^{2} }[/tex]

= [tex]\sqrt{(8-4)^{2}+(2-2)^{2} } =4[/tex]

Option C is correct.

Option D:

[tex](x_{1} ,y_{1})=(2,4)[/tex]

[tex](x_{2} ,y_{2})=(5,4)[/tex]

Distance = [tex]\sqrt{(x_{2} -x_{1} )^{2} +(y_{2}-y_{1} )^{2} }[/tex]

= [tex]\sqrt{(5-2)^{2}+(4-4)^{2} } =3[/tex]

Hence, (4,2) (8,2) points are separated by a distance of 4 units.

Answer:

I think it roughly 66.67%

Step-by-step explanation:

sorry if I'm no help

The percent of questions she answered correctly is 80%.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Given;

Lana correctly answered 48 of 60 questions on a math exam

Now,

=480/60

=80

Answer:

[tex]\frac{612}{999}[/tex]

Step-by-step explanation:

To convert repeating decimals to fractions, you take the numbers that are repeating, in this case 612, and you see how many numbers are repeating. Here we have 3 numbers repeating and so you would divide 612 by 3 9's meaning 999. So 0.612 repeating is equal to [tex]\frac{612}{999}[/tex]. To make sure the answer is right, you can divide the numbers in a calculator to make sure you get the correct decimal.

Answer:

1. False

2. False

3. True

Step-by-step explanation:

1. It fails the 'Vertical Line Test.' Draw a line through the center of the relation and see if the line passes through the graph more than once. It does, therefore it fails the test. Meaning it is not a function.

2. Domain (x) is all the x-values in the equation, the relation only contains the x-values x>0 and x<7 (0 - 7). Meaning it does not contain all real numbers.

3. The range (y) contains negative numbers because the relation is partially in the 4th quadrant, meaning it MUST contain a negative y-value.

Answer:

The zeros are:

[tex]x =4, x=2, x = 5[/tex]

Hence, option (B) is true.

Step-by-step explanation:

Given the expression

[tex]h\left(x\right)=\left(x-4\right)^2\left(x^2-7x+\:10\right)[/tex]

Let us determine the zeros of the function by putting h(x) = 0 and solving the expression

[tex]0=\left(x-4\right)^2\left(x^2-7x+10\right)[/tex]

switch sides

[tex]\left(x-4\right)^2\left(x^2-7x+10\right)=0[/tex]

as

[tex]x^2-7x+\:10=\left(x-2\right)\left(x-5\right)[/tex]

so

[tex]\left(x-4\right)^2\left(x-2\right)\left(x-5\right)=0[/tex]

Using the zero factor principle

so

[tex]x-4=0\quad \mathrm{or}\quad \:x-2=0\quad \mathrm{or}\quad \:x-5=0[/tex]

[tex]x =4, x=2, x = 5[/tex]

Thus, the zeros are:

[tex]x =4, x=2, x = 5[/tex]

It is clear that there are three zeros and all the zeros are distinct real numbers.

Therefore,

Hence, option (B) is true.

Answer:

x=2.5

Step-by-step explanation:

Answer:

0.35m + 25 = 42.50

Step-by-step explanation:

If you were to rent a truck for one day you will first have to pay a $25 fee for one day. This is represented by + 25 in the equation above.

Then for every mile you go you must pay $0.35, represented as 0.35m.

As an example to make it easier if you had to pay 1 dollar per mile and you went 10 miles it would cost $10. This can be proved by 1m (m being the variable for number of miles) Plug in 10 for m and you can asee 1(10)=10, because obviously 1 times 10 is 10.

Same premise with $0.35

Then both of those fees added up are equal to a total of $42.50.

To prove it can find the exact number of miles that need to be driven to cost a total of $42.50 just follow steps bellow.

1. 0.35m + 25 - 25 = 42.50 - 25

Subtracting the inital fee since it is part of the total, and if you add/subtract/multiply/divide on one side you must do to the other.

2. 0.35m/0.35 = 17.50/0.35

You divide because m is being multiplied with 0.35 and to undo the multiplication you divide. Doing the same to both sides.

3. m = 50

Plug in 50 to "m" in the equation above and if both sides are equal the answer is valid.
