This is the graph of the function f(x) = k(3). The value k is a constant. Based on the graph, what is the value of k
Answers
By using the graph, we will see that k = 1.85
How to find the value of K?
Here we have the exponential function:
f(x) = k*(3)^x
And we want to find the value of k.
To find it, we need to use one point on the graph. the only one easy to read is the one for x = 3, we can see that when x = 3, f(x) = 50.
Then we have:
f(3) = 50 = k*(3)^3 = k*(3*3*3) = 27*k
Solving that for k we get:
50 = 27*k
50/27 = k = 1.85

Answers
Answer:
A. 1.06
B. $6,784
Step-by-step explanation:
I = A - P = $384.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
A = 6400(1 + (0.06 × 1)) = 6784
A = $6,784.00
The total amount accrued, principal plus interest, from simple interest on a principal of $6,400.00 at a rate of 6% per year for 1 year is $6,784.00.

Answer:
x = 37
Step-by-step explanation:
2x and 74 are vertically opposite angles and are congruent, so
2x = 74 ( divide both sides by 2 )
x = 37
Step-by-step explanation:
To find the value of x, first, the denominators are made equal by taking the L.C.M. of them.
(3x + 2)/7 + (4(x + 1))/5 = 2/3 * (2x + 1) (45x + 30 + 84x + 84)/105 = (140x + 70)/105
Since both the sides of the equation have the same denominator now, they can be cancelled out.
45x + 30 + 84x + 84 = 140x + 70
The equation can be rearranged by shifting all the x terms on one side of the equation and all the constants on the other side of the equation.
140x - 85x - 45x = 84 + 30 - 70
10x = 44
x = 4.4
Therefore, the value of x is 4.4.

Subtract 101 from both sides...

If ⅙ of a roll of wallpaper covers ¼ of the wall. How many rolls of paper are needed to cover 4 walls?
Answers
Answer:
if 1/6 of a roll of paper covers 1/4 of a wall, this means that we will need 4/6 of a roll to cover a whole wall, now the question is asking how many rolls will we need to cover 4 walls, we already know that it takes 4/6 to fill one wall so if we add 4/6+4/6+4/6+4/6 we will get 16/6 or 2 4/6
we will need 16/6 or 2 4/6 of rolls of paper to cover 4 walls
If three times a number is increased by 24, the result is 16 less than seven times the same number. Find the number.
Answers
Answer:
10
Step-by-step explanation:
let x = unknown number
three times x is increased by 24
so 3x + 24
this is equal to 16 less than 7 times x
so 3x + 24 = 7x - 16
we now solve for x
3x + 24 = 7x - 16
add 16 to both sides
3x + 24 + 16 = 7x - 16 + 16
3x + 40 = 7x
subtract 3x from both sides
3x - 3x + 40 = 7x - 3x
40 = 4x
divide both sides by 4
40/4 = 10
4x / 4 =x
x=10

B) 50 represents the amount of money already present in the account when she starts saving. This is the y-intercept of the function.
C) It will take 5 weeks for her to save $150
Step-by-step explanation:
A) 20 represents the amount of money saved in one month or amount saved per month. This is the slope or rate of change of the function.
B) 50 represents the amount of money already present in the account when she starts saving. This is the y-intercept of the function.
C) The time to reach $150
150 = 20(w) + 50
20(w) = 150 - 50
20w = 100
w = 100/20
w = 5
It will take 5 weeks
A triangle has vertices at (−2, −2), (−2, −5), and (−4, −5). The triangle is translated 2 units to the right and rotated 90° clockwise about the origin. What are the coordinates of its image?
( , ), ( , ), ( , ) → ( , ), ( , ), ( , ),
Answers
Step-by-step explanation:
translated (shifted) 2 units to the right (positive x direction) creates the points
(-2 + 2, -2) = (0, -2)
(-2 + 2, -5) = (0, -5)
(-4 + 2, -5) = (-2, -5)
and now we rotate these points 90° clockwise around the origin.
that means a positive x turns into a negative y, a negative y into a negative x, a negative x into a positive y, and a positive y into a positive x.
and a 0 just trades places.
therefore,
(0, -2) becomes (-2, 0)
(0, -5) becomes (-5, 0)
(-2, -5) becomes (-5, 2)
so, overall
(-2, -2) becomes (-2, 0)
(-2, -5) becomes (-5, 0)
(-4, -5) becomes (-5, 2)
