Answer:

a. 2/3

b. [tex]\sqrt{2}[/tex]

c. 3

d. 5

e. 2

f. Undefined

Step-by-step explanation:

a. [tex]f(x)=\frac{|x-3|}{x+2}[/tex]

To find f(1), plug in 1 where every x is in the equation

[tex]f(1)=\frac{|1-3|}{1+2}=\frac{|-2|}{3}=\frac{2}{3}[/tex]

b. [tex]f(x) = \sqrt{x+1}[/tex]

[tex]f(1) = \sqrt{1+1}=\sqrt{2}[/tex]

c. [tex]f(x) = x^2+5x-3[/tex]

[tex]f(1) = (1)^2+5(1)-3=1+5-3=6-3=3[/tex]

d. [tex]f(x)=\frac{2x+3}{x}[/tex]

[tex]f(1)=\frac{2(1)+3}{1}=\frac{5}{1}=5[/tex]

e. [tex]f(x) = |2x-4|[/tex]

[tex]f(1) = |2(1)-4|=|2-4|=|-2|=2[/tex]

f. [tex]f(x)=\frac{7-2x}{x-1}[/tex]

[tex]f(1)=\frac{7-2(1)}{1-1}=\frac{5}{0}[/tex]

This equation is undefined when x=1 because 0 is the denominator of the fraction.

Answer:

61 beats = 4.88

72 beats = 5.76

Step-by-step explanation:

Firstly,you have to divide 61 to 12.5 then you can get 4.88. After that, you must divide 72 to 12.5 then you can get 5.76. Hope this will help you!

Answer:

(x +2) (x+ 8)

Step-by-step explanation:

2x^2 + 20x + 32

you have to multiply 32 by 2 bc the leading coefficient is >1, now find which multiples of 64 add up to 20, which is 16, and 4

(2x +4) (2x +16)   u have to simplify these bc the leading coefficient is >1, the gcf is 2, so divide by 2

(x + 2) (x + 8)

Answer: A

Step-by-step explanation:

[tex]\frac{6.3\cdot \:10^8}{9\cdot \:10^2}[/tex]

[tex]=\frac{6.3\cdot \:10^6}{9}[/tex] --> Exponent rule for division, 10^8/10^2 = 10^6

= 700,000 --> In scientific notation, 7.0×10^5

Answer:

it's 11 and x is 12

Answer:

y = 15

Step-by-step explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion, that is

[tex]\frac{y}{33}[/tex] = [tex]\frac{10}{22}[/tex] ( cross- multiply )

22y = 330 ( divide both sides by 22 )

y = 15

use a calculator it's way easier but here is the answer

Answer:

15%

Step-by-step explanation:

Total families:

[tex]45 + 38 + 27 + 10 = 120[/tex]

Difference between the families:

[tex]45 - 27 = 18[/tex]

Percentage calculation:

[tex]\% = \frac{18 \times 100}{120} = 15\%[/tex]

Step-by-step explanation:

3x + 6y - 5z

=3×3+-5×6-2×5

=9+-30-10

=9-40

=-31

Answer:

- 31

Step-by-step explanation:

x = 3

y = -5

z = 2

3x + 6y - 5z

3(3) + 6(-5) - 5(2)

9 - 30 - 10

9 - 40

- 31

Answer:

Explanation:

opposite angles in a quadrilateral sum up to 180°

total interior angles in a quadrilateral is 360°

solve for x:

x - 2 + x + 2 = 180°

2x = 180°

x = 90°

solve for each angle:

1st

x + 2

90° + 2 = 92°

2nd

x - 2

90° - 2 = 88°

3rd

x - 10

90° - 10° = 80°

4th

360° - 80° - 88° - 92° = 100°

Step-by-step explanation:

I don't believe it is scalene, maybe try looking it up?

Answer:

NO

Step-by-step explanation:

A scalene triangle has no sides equal. This triangle has two sides equal with 13 inches. This triangle is isosceles.

TW is the midsegment of the trapezoid UVXY

=> 2TW = XY + UV

=> 2(z - 2) = 4z - 34 + z

=> 2z - 4 = 5z - 34

=> 5z - 2z = 34 - 4

=> 3z = 30

=> z = 10

Answer: z = 10

Ok done. Thank to me :>

Answer:

$272559.70

Step-by-step explanation:

So, let's start with what we know

This problem should be solved with the formula

A = P ( 1 + r/n)^nt

The variable A is the final amount

A = 3000000

This is the amount we want to achieve

The variable P is the principle, the amount of money you put in a bank to earn interest

We have to solve for this value

The variable r is the interest rate

r = 0.065

Note: I converted the percent to a decimal, so we can use it in the formula

The variable n is the amount of times interest is compounded

n = 12

The interest is compounded monthly in a year, so 12 times

The variable t is the amount of time you have to earn the interest

t = 37

So, let's solve for the value P with the values we know

3000000 = P ( 1 + 0.065/12)^(12x37)

3000000 = P(11.0067628047)

3000000 / 11.0067628047 = P(11.0067628047) / 11.0067628047

272559.702905 = P

P = 272559.70

Note: I rounded to the nearest cent, since there isn't a value of USD lower than 1 cent.

So, there you have it, a principle of 272559.70 will get you 3000000 in 37 years given that interest is compounded monthly at 6.5% interest rate

Answer:

x = 9

Step-by-step explanation:

2x + 15 = 5x - 12 (since it is parallel)

15 + 12 = 5x - 2x

27 = 3x

x = 9

Answer:

Approximately Normal

Step-by-step explanation:

Since we're given a normally distributed population, the sampling distribution of the sample means will also be normally distributed, even when the sample size is small.

Using error concepts, it is found that in this problem, a type I error would be finding an innocent person guilty, while a type II error would be finding a guilty person innocent.

Hence:

In this problem, a type I error would be finding an innocent person guilty, while a type II error would be finding a guilty person innocent.

Answer:

6mm

Step-by-step explanation:

A rectangle with all sides equal is a square

Area=a

36=a

a=6mm

Answer:

All you need to do is subtract the coefficient.

Step-by-step explanation:

For example a minus b is c. So this is simply going to be c times d to the e you can do that if these two are the same.
