jeyben [28]

Answer:

B. 5, 20, 80, 320.

Step-by-step explanation:

f(1) = 5

After the first rem, each term id 4 times the previous term,  so:

f(2) = 4f(1) = 4*5 = 20.

f(3) = 4f(2) = *20 = 80

f(4) = 4(f3) = 4*80 = 320.

On a coordinate plane, triangle R S T has points (negative 5, 6), (3, 4), and (negative 2, 2). Which expression can be used to f
pav-90 [236]

The area of a triangle is the amount of space on the triangle

The expression that represents the area of the triangle is A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|

The coordinates of the triangle are given as:

R = (-5,6)

S = (3,4)

T = (-2,2)

The area (A) of a triangle from its coordinates or vertices are:

A = \frac 12|x_1(y_3 -y_2) +x_2(y_3 -y_1) + x_3(y_2 -y_1)|

Substitute values for x's and y's

A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|

Hence, the expression that represents the area of the triangle is A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|

Joseph and Isabelle left Omyra’s house at the same time. Joseph jogged north at 8 kilometers per hour, while Isabelle rode her b
Artist 52 [7]
For this case the distance will be given by:
 d ^ 2 = (12 * 1.5) ^ 2 + (8 * 1.5) ^ 2
 Rewriting we have:
 d ^ 2 = (18) ^ 2 + (12) ^ 2
 d ^ 2 = 324 + 144
 d ^ 2 = 468
 d = root (468)
 d = 21.63 Km
 Answer:
 
1) She did not find the full distance each traveled in 1.5 hours.
 
2) She should have used 12 km for Joseph's distance and 18 km for Isabelle's distance.
