Answer:
B
Step-by-step explanation:
We dont know rules about rotating a point. We only know rules about rotating about the orgin.
We can translate this line segment so point c is on the orgin because
- A translation is a rigid transformation
- We also know rotation rules about the orgin.
Point C is at (1,3) so let move this all points 1 to the left and 3 down. Why All Points?
A translation is parallel from it original image to its second or new image so this means Point B and Point A will both move as well. Let just focus on Point A. The new coordinates are:
Let apply the 90 degree clockwise rule. Point C doesnt move since it is at the orgin and it at the center of rotation.
(x,y) goes to (y,-x).
So Point A prime is now at
(0,-1).
Now let translate the figure back to Point C (1,3). by going 1 to the right and 3 up so our new point of Point A prime is at
(1,2).
Answer:
x = 1
Step-by-step explanation:
Now we have to,
→ find the required value of x.
Let's solve the problem,
→ 15 = 2x + 13
→ 2x + 13 = 15
→ 2x = 15 - 13
→ x = 2/2
→ [ x = 1 ]
Hence, the value of x is 1.
Answer:
Area: T = 18
a. The triangle area using Heron's formula: T= sqrt(s(s−a)(s−b)(s−c)
)
b. 2
c. h = 5.69
d. T = 18
Step-by-step explanation:
a. T= sqrt(s(s−a)(s−b)(s−c)
)
T=sqrt(
11.16(11.16−10)(11.16−6)(11.16−6.32)
)
T= sqrt(324
)
T =18
b. We compute the base from coordinates using the Pythagorean theorem
c= sqrt( ((−2−4)^2)+ ((1−3) ^2)
)
c= sqrt(40) = 2sqrt(10)
c. Calculate the heights of the triangle from its area

Answer:
y=425*250^1.083
Step-by-step explanation:
It wants to write an equation of that models the amount of money in the account each month for the first year.
We need the Exponential Equation Formula: y=a*bx
Y is the amount of money in the account.
a is the initial amount he starts with
b is the amount being added each month
x is the rate of return
So, y=425*2501.083
