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

What's the question
Step-by-step explanation:
???
The temperature of a place was 32⁰C on Friday. On Saturday it rose by 4⁰C, then rainfall on Sunday caused the temperature to fall by 7⁰C. What was the final temperature on Sunday?
Given :
The temperature of a place was 32⁰C on Friday. On Saturday it rose by 4⁰C, then rainfall on Sunday caused the temperature to fall by 7⁰C.
To Find :
The final temperature on Sunday.
Solution :
Temperature on Saturday = initial temperature + 4⁰C
= 32⁰C + 4⁰C
= 36⁰C.
Temperature on Sunday = temperature on Saturday - 7⁰C
= 36⁰C - 7⁰C
= 29⁰C
Therefore, final temperature on Sunday is 29⁰C.
Hence, this is the required solution.
Solve the equation.

y –5 0 5 10 15
Function B:
y = –4.5x + 15
Function A has a rate change of BLANK and Function B has a rate change of BLANK so Function BLANK has a greater rate of change
Answer:
5; -4.5; Function AStep-by-step explanation:
Rate of change for function A is:
(15 - 10)/(5.5 - 4.5) = 5/1 = 5Rate of change of function B is:
-4.5 as the slope is the rate of changeComparing the values:
5 > - 4.5Function A has a greater rate of change
Answer:
Answer:
5; -4.5; Function A
Step-by-step explanation:
Rate of change for function A is:
(15 - 10)/(5.5 - 4.5) = 5/1 = 5
Rate of change of function B is:
-4.5 as the slope is the rate of change
Comparing the values:
5 > - 4.5
Function A has a greater rate of change

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]

Susan won $2000 and invested it into an account with an annual interest rate of 3.2%. If her investment were compounded monthly, which expression best represents the value of her investment after t years
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]
Calculation of the expression: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]

[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].
What is trigonometric expression?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]

Jenny got a haircut before school started. The stylist cut 0.36 inch off Jenny's hair. Which fraction and percent are equivalent to the amount of Jenny's hair the stylist cut off?
Answer:
The fraction equivalent to the amount of Jenny's hair the stylist cut off is [tex]\frac{9}{25}[/tex] inch.
The percentage equivalent to the amount of Jenny's hair the stylist cut off is 36% inch.
Step-by-step explanation:
From the question, the stylist cut 0.36 inch off Jenny's hair.
To determine what fraction is equivalent to the amount of Jenny's hair the stylist cut off, we will express 0.36 inch as a fraction.
[tex]0.36 = \frac{36}{100}[/tex]
Then, we will reduce [tex]\frac{36}{100}[/tex] to a fraction in its lowest term
[tex]\frac{36}{100} = \frac{9}{25}[/tex]
Hence, the fraction equivalent to the amount of Jenny's hair the stylist cut off is [tex]\frac{9}{25}[/tex] inch.
For the percentage equivalent to the amount of Jenny's hair the stylist cut off, we will express [tex]\frac{9}{25}[/tex] as a percentage. That is
[tex]\frac{9}{25} \times 100[/tex]%
= 36%
Hence, the percentage equivalent to the amount of Jenny's hair the stylist cut off is 36% inch.
