Riley invested $8,500 in an account paying an interest rate of 3.8% compounded daily. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $18,040?
Answer:
Answer:
First we subtract 8,500 from the 18,040. What we get from that is 9540. Now we divide 9,540 by 3.8 and see what we get. What we get is 2510.52631579 which means it would take around 2510.52631579 days to pay 18,040. In total that rounds to 7 years. Rounding up by the way

help i’m confused♀️ kinda forgot what a inequality is over quarantine lol
Answer:
t ≤ 10
Step-by-step explanation:
To solve the inequality, simplify it.
-3t + 9 ≥ -21
Subtract 9 from both sides.
-3t ≥ -30
Divide by -3. When dividing by a negative, flip the inequality sign.
The answer is C, t ≤ 10.

A trapezoid has a height of 6 inches, an area of 120 square inches, and one base measuring 13 inches. Find the length of the other base.
Answer:
27
Step-by-step explanation:
Givens
b1 = 13
b2 = ?
h = 6
Area = 120
Formula
Area = (b1 + b2) * h/2 Multiply by 2
2Area = (b1 + b2)*h Divide by h
2Area/h = b1 + b2 Subtract b1 from both sides
2Area/h - b1 = b2
Solution
2*120 / 6 - 13 = b2
40 - 13 = b2
b2 = 27

The triangle below has a perimeter of 20. Solve for x
Answer:
x = 5
Step-by-step explanation:
Given that,
First side of a triangle = x+2
The second side of a triangle = 8
The third side of a triangle = x
We know that, perimeter is equal to the sum of all sides. So,
x+2+x+8 = 20
2x+10 = 20
2x = 10
x = 5
Hence, the value of x is equal to 5.

What number am I? All of my digits are even. My tens digit is equal to two more than my hundreds digit. My ones digit is equal to two more than my tens digit.
Answer:
246 or 468.
Step-by-step explanation:
The only possible even digits are 2, 4, 6, and 8 (0 is neither even nor odd).
Therefore, your possible numbers are 246 and 468.

Find the area of the shaded sector. Blue Cross.
Write the equation of a circle with a center of (1,-2) and radius of 4.
Answer:
(x - 1)^2 + (y + 2)^2 = 4^2
Step-by-step explanation:
The standard equation of a circle of radius r with center at (h, k) is
(x - h)^2 + (y - k)^2 = r^2
Replacing h with 1, y with -2 and r with 4, we get:
(x - 1)^2 + (y + 2)^2 = 4^2
does anyone know how to do this or could explain how they got their answer?
Answer:
c
Step-by-step explanation:
Answer:
using trigonometric ratio sin, which is
sin[tex]\alpha[/tex]=opp/hyp to mean opposite/ hypotenuse
sin 40°= x/9
multiply both sides of this by 9 to remove the 9 in the side we have x, we will have
sin 40°/9=x
sin° 40 =0.7451
so x= 0.7451/9
which is
x= 0.0827888888
to give it in 3 decimal places, the answer will be 0.083 since 7 is the fourth number and is more than five, we add 1 to the 2 making it 3

Select all the correlation coefficients that represent a linear model with a weak correlation .
A. -0.982
B. -0.618
C. -0.103
D. 0.204
E. 0.907
F. 1
Answer:
C) -0.103 and D) 0.204
Step-by-step explanation:
A linear model with a weak correlation is gonna have an r value closest to 0, whether it be negative or positive. C and D seem to be the best choice as they're closest to 0.

What is the absolute maximum or minimum of f(x) = 3x^2-5x-9
Answer:
Absolute minimum / vertex = (5/6,-133/12)
Step-by-step explanation:
Since a is positive, then the absolute maximum is ∞. The absolute minimum would be the vertex of the parabola, meaning x=-b/2a=-(-5)/2(3)=5/6, and y=3(5/6)^2-5(5/6)-9 = -133/12. Therefore, your absolute minimum / vertex is (5/6,-133/12)
Noha rides his bike 4 miles and andrew rides his bike 2 miles how long dose it take for them to meet up( there 15 miles away
Step-by-step explanation:
Considering speed of Noha = 4miles per hour
and speed of andrew = 2 miles/hour
The distance between Noha and andrew = 15 miles
Case 1: when they are travelling towards each other( opposite direction)
Then their relative speed becomes = 4+2 = 6miles/hour
Time taken to meet = Distance/relative speed = 15/6 = 2.5 hours
Case2: When they are travelling same direction
Then their relative speed becomes = 4-2 = 2 miles/hour
Time taken to meet = Distance/ relative speed = 15/2 = 7.5 hours
A westbound train travels 16 miles per hour slower than the eastbound train. If two trains are 800 miles apart after 5 hours what is the rate of the westbound train?
Answer:
6
Step-by-step explanation:
The rate can be calculated as follows
x + x -16
2x-16
(2x-16)×5
10x - 80= 800
10x = 300-80
10x, = 220
x = 220/10
= 22
22-16
= 6 mph
Hence the rate of the west bound tsin is 6mph
someone help please :(
Answer:
D
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift left of a units
• If a < 0 then a shift right of a units
Then
g(x + 3)² is the graph of f(x) translated 3 units left
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Then
g(x) = g(x + 3)² - 7 is the graph of f(x)
Translated 3 units left and 7 units down
