Answer:Check the options well. My answer isn't in the options
Step-by-step explanation:
Write the equation of the line in fully simplified slope intercept form.
Step-by-step explanation:
the line passes (-10, 0) and ( (0, 8) =>
the slope = (8-0)/(0-(-10) = 8/10 = 4/5
so, the equation :
y - 8= 4/5 ( x-0)
y -8 = 4/5 x
=> y = 4/5 x + 8
Is this right???????
Answer:
Yes
Step-by-step explanation:
What would the sum of the interior angles of a 14 sided shape be?
Select one:
O a. 360°
O b. 180°
O c. 14°
O d. 2,160°
Answer:
the sum of interior angles of a 14 sided shape be 2160
Answer: D) 2160
Work Shown:
S = sum of the interior angles of a polygon with n sides
S = 180(n-2)
S = 180(14-2)
S = 180*12
S = 2160
Using the segment addition postulate find the length of the segment EF
Answer:
10
Step-by-step explanation:
I'm pretty sure the segment addition postulate just means that if you add JK and KL together, you'll get the length of JL. Correct me if I'm wrong...
Anyways, JK = 3x - 4, and KL = 5x + 6. If we add these together, according to the segment addition postulate, we will get JL, which equals 9x - 8. So, we set up an equation:
3x - 4 + 5x + 6 = 9x - 8
Simplifying this equation, we get:
8x + 2 = 9x - 8
x = 10
So, our answer is 10.
(also you ask for segment EF but I don't see segment EF so I'm going to just answer the question in the picture)
Giving out bonus points if you answer this!

a. Find the value of sin2A, cos2A, tan2A and cot2A when sinA = 4/5 , cosA =4/5, tanA= 3/4 and cotA = 12/13
Step-by-step explanation:
Given,
SinA = 4/5
CosA =4/5
TanA= 3/4
CotA = 12/13
Sin²A = SinA²
Cos²A = CosA²
Tan²A = TanA²
Cot²A = CotA²
Therefore,
Sin²A = (4/5)²
Cos²A = (4/5)²
Tan²A = (3/4)²
Cot²A = (12/13)²
Sin²A = 16/25
Cos²A = 16/25
Tan²A = 9/16
Cot²A = 144/169

What is 10% of a number whose square
is 81
Answer: 0.9
Step-by-step explanation:
Let x be the number
Determine the value of the number
x² = 81
√x² = √81
x = 9
Find the 10% of the number
Final number = rate of percentage × original number
Final number = 10% × 9
Final number = [tex]\boxed{0.9}[/tex]

Answer:
second option ∠C = 60 degrees
Step-by-step explanation:
To find the angle C
we know that the sum of all interior angles of triangle is 180
∠A + ∠B + ∠C = 180 (sum of interior angles)
90 + 30 + ∠C = 180
120 + ∠C= 180
∠C = 180 - 120
∠C = 60
Answer: B. 60
Concept:
Here, we need to know the idea of the triangle angle sum theorem.
The triangle angle sum theorem states that the sum of interior angles is 180 degrees.
Step-by-step explanation:
Given information
∠A = 90°
∠B = 30°
∠C = unknown
Given expression deducted from the triangle angle sum theorem
∠A + ∠B + ∠C = 180
Substitute values into the expression
90 + 30 + ∠C = 180
Combine like terms
120 + ∠C = 180
Subtract 120 on both sides
120 + ∠C - 120 = 180 - 120
∠C = [tex]\boxed{60}[/tex]

Answer:
A) $49
Step-by-step explanation:
There are two ways to solve this problem. You could either calculate the net change by adding up the values in the table and then adding that to the initial amount, or you could individually add every change in price to the initial amount. I'm going to go with the first way, as I find it to be quicker, but both methods work equally well.
We know that the stock was worth $52 on Monday morning. From the table, the net (or overall) change in the stock over the course of the week is:
-2 + 1 + 3 - 1 - 4 = -3
Therefore, the stock's price decreased by $3 over the week, and because the stock's original price was $52, we know it is now worth 52 - 3 = $49. Hope this helps!
