Answer:
Step-by-step explanation:
f(0) = -2
f(1) = 3*(f(1 - 1)) - 2*1
f(1) = 3(-2) - 2
f(1) = - 6 - 2
f(1) = - 8
f(2) = 3*(f(1)) - 2*2
f(2) = 3*(-8) - 4
f(2) = -24 - 4
f(2) = - 28
f(3) = 3*(f(2)) - 2*3
f(3) = 3*-28 - 6
f(3) = -84-6
f(3) = - 90
f(4) = 3*f(3) - 2 * 4
f(4) = 3*-90 - 8
f(4) = -270 - 8
f(4) = -278

Mary wanted to solve the system of equations shown. She first used row reduction to get the system into 2 equations with 2 variables, x and y. She then used her calculator and got the graph shown. What is the solution to her system?
Answer: (2, -1, 3)
Step-by-step explanation:
The graph shows you that x=2 and y=-1 so, plug those values back into one of the equations to solve for z. You should get z=3 giving you a solution of (2, -1, 3).

Answer:
$32.60
Step-by-step explanation:
Remember to find the percentage of something, times the number by the percentage, which is two decimals to the left. So 15% would be 0.15.
The total is unknown so replace it with a variable, such as x
.15(x)=4.89
Isolate x by dividing both sides by 0.15
x=32.6
Meal price: $32.60
Check your answer by multiplying this number by the tip percentages
32.6(.18)=5.87
32.6(.20)= 6.52
There are 18 children in Haley's preschool class. During free time yesterday, 3 of them chose to play with blocks. What is the probability that a randomly selected child chose to play with blocks yesterday?
Answer:
3/18
Step-by-step explanation:
Out of the 18 kids, three of them did, so 3/18, which can be simplified to 16.6666%, so 17% if you round it to the nearest degree.

M&M plain candies have a normally distributed weight with a mean of 0.8565 g and a standard
deviation of 0.0518 g. If 465 M&M plain candies are randomly selected, find the probability that
their mean weight is at least 0.8535 g each.
Answer:
0.89417
Step-by-step explanation:
Using the relation to obtain the Zscore :
Z = (x - mean) ÷ standard deviation / sqrt(n)
x = 0.8535
Mean = 0.8565
Standard deviation = 0.0518
Sample size, n = 465
P(x ≤ 0.8535) = (0.8535 - 0.8565) ÷ 0.0518/sqrt(465)
P(x ≥ 0.8535) = - 0.003 / 0.0024021
P(x ≥ 0.8535) = - 1.249
P(Z ≥ - 1.249) = 0.89417

Answer:
DCB=33
Step-by-step explanation:
We are given the angle for a and we know the angle for ADC is 90 because AB & DC are perpendicular. Given two angles of a triangle we can find the third by subtracting the two known values from 180 because we know a triangle totals 180.
180-33-90=57
So we can also find CDB because we know AB & DC are perpendicular. It is also 90 because two perpendicular lines make a 90 angle.
DCB can be found because we know that ACB makes a 90 angle and the ACD portion is 57. So we subtract 57 from 90.
90-57=33
We can also find CBD by subtracting CDB and DCB from 180.
180-90-33=57

A ring-shaped region is shown below. Its inner radius is 19 m, and its outer radius is 24 m. Find the area of the shaded region. Use 3.14 for . Do not round your answer.
Answer:
675.1 sq m
Step-by-step explanation:
Area of larger circle = 3.14(24^2) = 3.14(576) = 1808.64
area of smaller circle = 3.14(19^2) = 3.14(361) = 1133.54
area of ring = Area of larger circle - area of smaller circle
= 1808.64 - 1133.54 = 675.1

6x^2+3x+24=0 solve by factoring
Answer:
No real solutions
Step-by-step explanation:
Let's solve your equation step-by-step.
6x2+3x+24=0
For this equation: a=6, b=3, c=24
6x2+3x+24=0
Step 1: Use quadratic formula with a=6, b=3, c=24.
x= (−b±√b2−4ac) /2a
x=( −(3)±√(3)2−4(6)(24))/ 2(6)
x= (−3±√−567) /12
