Answer: 76

Step-by-step explanation: 29 + 47

Answer:

1, 2, 5, 12, 13

Step-by-step explanation:

∠1 = 90 is given, which is a right angle

∠3 = 90 as well because ∠1 and ∠3 are vertically opposite

∠3 = ∠8, because ∠1 and ∠8 are same side exterior angles, which are the same

Therefore ∠3 must be congruent to ∠8

Answer:

a= −b/x

Step-by-step explanation:

Let's solve for a.

ax2+bx=0

Step 1: Add -bx to both sides.

ax2+bx+−bx=0+−bx

ax2=−bx

Step 2: Divide both sides by x^2.

ax2x2=−bxx2

a=−bx

Answer:

Step-by-step explanation:

perfect sqaure formula (u+w)²=u²+2uw+w²

ax²+bx+c=0  divide by a

[tex]x^{2} +\frac{bx}{a} + \frac{c}{a} =0[/tex]  so u=1, 2uw=2*1*w= b/a, so w=b/2a

[tex](x^{2}+ \frac{bx}{a} +\frac{b^{2} }{4a^{2} } ) +\frac{c}{a} -\frac{b^{2} }{4a^{2} }=0[/tex] now that we formed the perfect sqare solve

[tex](x +\frac{b}{2a} )^{2} +\frac{c*4*a-b^{2} }{4a^{2} } =0[/tex] but we can factor a negative in front of the fraction

[tex](x+\frac{b}{2a} )^{2} -\frac{b^{2} -4ac }{4a^{2} } =0[/tex] now isolate the 2 terms and squareroot both sides

[tex]\sqrt{ (x +\frac{b}{2a} )^{2}} =\sqrt{ \frac{b^{2} -4ac }{4a^{2} } }[/tex] and you will be left with

[tex]x +\frac{b}{2a} =\ + - \frac {\sqrt{ b^{2} -4ac} }{2a }[/tex]  subtract b/2a from both sides

x= [tex]\frac{-b+ - \sqrt{b^{2}-4ac } }{2a}[/tex]

Answer:

C

Step-by-step explanation:

I just plugged it in and checked tbh

The point C = ( 2, 1 ) lies on the line 3y = 2x - 1.

The standard form of the equation of a line is given as:

ax + by + c = 0.

Here a, and b, are the coefficients, x, and y are the variables, and c is the constant term.

We have,

Equation of a line:

3y = 2x - 1

We need to check which point lies on the line.

A = ( 2, 6 )

3 x 6 = 2 x 2 - 1

18 = 4 - 1

18 ≠ 3

B = ( 1, 2 )

3 x 2 = 2 x 1 - 1

6 = 2 - 1

6 ≠ 1

C = ( 2, 1 )

3 x 1 = 2 x 2 - 1

3 = 4 - 1

3 = 3

D = ( -2, 1 )

3 x 1 = 2 x (-2) - 1

3 = -4 - 1

3 ≠ -5

E = ( 2, -6 )

3 x (-6) = 2 x 2 - 1

-18 = 4 - 1

-18 ≠ 3

Thus the point C = ( 2, 1 ) lies on the line 3y = 2x - 1.

The initial value of f(x) is 0.

The range of values for f(x) is 0 ≤ f(x) ≤ 6.

*Hint: You can use a table to do this one and plug in -4, -3, -2, and -1 in for x in the rule for the function of f(x), and -4 is your initial x-value. The answer from the first line is the same answer for the other blank.

Step-by-step explanation:

Edge 2020

[tex]sin(\frac{\pi }{12})cos(\frac{7\pi}{12}) -cos(\frac{\pi }{12})sin(\frac{7\pi }{12})[/tex] is equivalent to [tex]sin(\frac{-\pi }{2} )[/tex].

Trigonometric expressions are non-routine appearing problems. They are unfamiliar because the language of trigonometry looks foreign and complicated. In order to learn how to simplify or reduce the complexity of trigonometric expressions, we first need to examine the identities we need to utilize.

It is one of the identities of trigonometry

sinAcosB - cosAsinB = sin(A - B)

Given expression

[tex]sin(\frac{\pi }{12})cos(\frac{7\pi}{12}) -cos(\frac{\pi }{12})sin(\frac{7\pi }{12})[/tex]

It is in form of sinAcosB - cosAsinB = sin(A - B)

⇒ [tex]sin(\frac{\pi }{12})cos(\frac{7\pi}{12}) -cos(\frac{\pi }{12})sin(\frac{7\pi }{12})[/tex] = [tex]sin(\frac{\pi }{12}-\frac{7\pi }{12} )[/tex]

⇒ [tex]sin(\frac{\pi }{12})cos(\frac{7\pi}{12}) -cos(\frac{\pi }{12})sin(\frac{7\pi }{12})[/tex] = [tex]sin(\frac{-6\pi }{12} )[/tex]

⇒ [tex]sin(\frac{\pi }{12})cos(\frac{7\pi}{12}) -cos(\frac{\pi }{12})sin(\frac{7\pi }{12})[/tex] = [tex]sin(\frac{-\pi }{2} )[/tex]

Hence [tex]sin(\frac{\pi }{12})cos(\frac{7\pi}{12}) -cos(\frac{\pi }{12})sin(\frac{7\pi }{12})[/tex] is equivalent to [tex]sin(\frac{-\pi }{2} )[/tex].

Answer:

FV= PV*(1+i)^t

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $2,000

Interest rate (i)= 3.2% = 0.032

Number of periods= t

To calculate the future value (FV) of the investment, we need to use the following formula:

FV= PV*(1+i)^t

For example, Susan invests for 4 years:

FV= 2,000*(1.032^4)

FV= $2,268.55

The expression best represents the value of her investment after t years is [tex]FV= PV\times (1+i)^t[/tex]

Since

Susan won $2000 and invested it into an account with an annual interest rate of 3.2%.

Here Number of periods= t

Therefore we can conclude that The expression best represents the value of her investment after t years is [tex]FV= PV\times (1+i)^t[/tex]

Answer:

You can not reduce it further only in decimals

Answer:

37.5 units

Step-by-step explanation:

I assume that there is condition: BC║DE . If so, then ΔABC ~ ΔADE ⇒ that corresponding sides are proportional.

[tex]\frac{BC}{DE}[/tex] = [tex]\frac{AC}{AE}[/tex]

AC = 30 + 20 = 50

[tex]\frac{x}{15}[/tex] = [tex]\frac{50}{20}[/tex] ⇒ x = [tex]\frac{15*50}{20}[/tex] = 37.5 units

Answer:

y=$25x+30

Step-by-step explanation:

This is the correct answer. The reason is that the equation is y=mx + b. b is like y-intercept, and that answer would be $30. $25x is correct because the question says per month, and when you see that it means ¨x¨.
