If f(x)= 2x-2 and g(x) =x^2 -8x+19, then f(x)=g(x) for what values of x?

Answer:

The sales tax is 2.8 and the total cost is 72.8.

Step-by-step explanation:

4% = 0.04

70.00 × 0.04 = 2.8

70 + 2.8 = 72.8

Answer:

Tax is $2.80

Step-by-step explanation:

When you multiply $70 by 0.04 (4% in decimal form), that is the answer you get, which tells you how much the sales tax is.

Answer:

Angles are the same, So:

C = G = 125

H = D = 75

A = E = 360 - ( 90+75+125) = 70

To know the ratio between the lengths. Divide 6 by 9 so you get 2/3

So every side of small polygon equals 2/3 times side of big polygon. ( THE PARALLEL ONES )

So:

FG = 7* 2/3 = 14/3

GH = 11 * 2/3 = 22/3

EH = 12 * 2/3 = 8

Answer:

A. Right triangle

Answer:

x =14.4

Step-by-step explanation:

Since the triangles are similar, we can use ratios to solve

x         9

----- = ------

8          5

Using cross products

5x = 9*8

5x = 72

Divide each side by 5

5x/5 = 72/5

x =14.4

Answer:

Jiri is 24 years old.  

Step-by-step explanation:

Let "J" represent Jiri's age.

We could use "P" to represent Pamela's age, but that wouldn't help us in solving this problem.

However, we do know that Pamela's age is 3 times Jiri's age, so we can write Pamela's age to be 3J (3 times Jiri's age.)

We also know that the sum of their ages is 96.

Thus, we have: Jiri's Age + Pamela's Age = 96 years of age.

And: J + 3J = 96

Simplifying, we obtain: 4J = 96

Divide by 4 on both sides: J = 24

Step-by-step explanation:

Answer: 1/25

Step-by-step explanation:

n^p=5^(-2)

5^-2=1/(5^2)

1/(5^2)=1/25

Answer:

I don't know how to do

Step-by-step explanation:

i don't know how to do sorry because I very busy

Answer:

No!

Because it doesn’t justify Pythagorean theorem.

D1= sqrtof( (3-2)^2+ (6-3)^2) = sqrtof 13

D2= sqrtof((6-3)^2+(5-6)^2)= sqrtof 10

D3= sqrtof((6-2)^2+(5-3)^2= sqrtof 20

Since D3 is longest, hypotenuse h= D3

Let’s p= D1 and b= D2

Pythagorean theorem is

p^2+b^2=h^2

If you place the value for p,b,h it doesn’t satisfy Pythagorean theorem. Thus, it is not right angle triangle.

Answer:

No real solution

Step-by-step explanation:

Given that,

A quadratic equation [tex]50-x^2=0[/tex]

We need to find the value of x.

[tex]50-x^2=0\\\\\text{or}\\\\x^2=50\\\\x=\sqrt{2\times 5\times 5} \\\\=5\sqrt2[/tex]

So, the value of x is [tex]5\sqrt2[/tex]. It has no real solution.

Answer:

The original price of the item is $250.

Step-by-step explanation:

Given that:

Amount of tax added to price of item = $23.50

Percent of sales tax = 9.4% = [tex]\frac{9.4}{100} = 0.094[/tex]

Let,

x be the original price of the item.

0.094 of x = 23.50

0.094x = 23.50

Dividing both sides by 0.094

[tex]\frac{0.094x}{0.094}=\frac{23.50}{0.094}\\x=250[/tex]

Hence,

The original price of the item is $250.

Answer:

1 ring

Step-by-step explanation:

10 items total

Half are necklaces = 5 necklaces out of the total 10 items

2/5 of the other items are bracelets = 2/5*10 = 4 necklaces total 10 items

This leaves only the rings, and 5 + 4 = 9, so 10 - 9 = 1 ring out of the total 10 items.

Answer:

5/2

Step-by-step explanation:

Since z=2,

then 5/z becomes 5/2

Answer:

6 3/4

Step-by-step explanation:

to write 54/8 into the mixed number and in the simplest form

we first simpify 54/8 which is 27/4

to convert 27/4 into a mixed number we first see how many times does 4 goes into 27 with the remainder. 4 goes into 27 6 times with the remainder of 3.  4 goes into 27 6 times so, 6 will be the whole part 3 remainder will be the numerator and 4 will be the denominator. like 6[tex]\frac{3}{4}[/tex]

Answer:

Well 0.5 is the same as 1/2 but I'll try to help.

Step-by-step explanation:

1/9+1/8 is 0.2361. That would honestly be closer to zero but the way that it is worded, it is closer to 1/2 because you are using fractions in the problem. If you were using decimals, I would use 0.5

Answer:

3π square units.

Step-by-step explanation:

We can use the disk method.

Since we are revolving around AB, we have a vertical axis of revolution.

So, our representative rectangle will be horizontal.

R₁ is bounded by y = 9x.

So, x = y/9.

Our radius since our axis is AB will be 1 - x or 1 - y/9.

And we are integrating from y = 0 to y = 9.

By the disk method (for a vertical axis of revolution):

[tex]\displaystyle V=\pi \int_a^b [R(y)]^2\, dy[/tex]

So:

[tex]\displaystyle V=\pi\int_0^9\Big(1-\frac{y}{9}\Big)^2\, dy[/tex]

Simplify:

[tex]\displaystyle V=\pi\int_0^9(1-\frac{2y}{9}+\frac{y^2}{81})\, dy[/tex]

Integrate:

[tex]\displaystyle V=\pi\Big[y-\frac{1}{9}y^2+\frac{1}{243}y^3\Big|_0^9\Big][/tex]

Evaluate (I ignored the 0):

[tex]\displaystyle V=\pi[9-\frac{1}{9}(9)^2+\frac{1}{243}(9^3)]=3\pi[/tex]

The volume of the solid is 3π square units.

Note:

You can do this without calculus. Notice that R₁ revolved around AB is simply a right cone with radius 1 and height 9. Then by the volume for a cone formula:

[tex]\displaystyle V=\frac{1}{3}\pi(1)^2(9)=3\pi[/tex]

We acquire the exact same answer.
