Answer:
16683 candiesStep-by-step explanation:
Given:
Initial value is 45000.Reduction per day is 18%.The equation would be:
[tex]C(t) = 45000*(1 - 0.18)^t=45000*0.82^t[/tex], where C(t) is the number of candies left after t daysFind the value of C(5):
C(5) = 45000*0.82⁵ ≈ 16683 rounded[tex]\\ \sf\longmapsto C(t)=P\left(1-\dfrac{R}{100}\right)^t[/tex]
[tex]\\ \sf\longmapsto C(t)=45000\left(1-\dfrac{18}{100}\right)^t[/tex]
[tex]\\ \sf\longmapsto C(t)=45000(1-0.18)^t[/tex]
[tex]\\ \sf\longmapsto C(t)=45000(0.82)^t[/tex]
Now
[tex]\\ \sf\longmapsto C(5)=45000(0.82)^5[/tex]
[tex]\\ \sf\longmapsto C(5)=45000(0.37)[/tex]
[tex]\\ \sf\longmapsto C(5)\approx16650[/tex]

Please help I’ll mark as brainliest!! And explain why too
Answer:
A=2 B=1
Step-by-step explanation:
B is distributive because you have to foil the x out of the parenthesis
A is because when three or more numbers are added (or multiplied), the sum (or the product) is the same regardless of the grouping of the addends.

3/4t=1/4
PLEASE HELP
Answer:
1/3
Step-by-step explanation:
1) Simplify 3/4t to 3t/4
3t/4 = 1/4
2) Multiply both sides by 4
3t = 1/4 x 4
3) Cancel 4
3t = 1
4) Divide both sides by 3
t = 1/3

Trapezoid LMNO is dilated by a scale factor of 3/4 to form trapezoid L'M'N'O'. Side O'L' measures 6. What is the measure of side OL?
Dilating a trapezoid involves changing its size.
The measure of side OL is 8
The given parameters are:
[tex]\mathbf{O'L' = 6}[/tex]
[tex]\mathbf{k = \frac 34}[/tex]
Side length O'L' is calculated using:
[tex]\mathbf{O'L' = OL \times k}[/tex]
Make OL the subject
[tex]\mathbf{OL = \frac{O'L'}{k}}[/tex]
So, we have:
[tex]\mathbf{OL = \frac{6}{3/4}}[/tex]
[tex]\mathbf{OL = 8}[/tex]
Hence, the measure of side OL is 8

Find rational zeros
Answer:
(x - 2) • (x - 4) • (x - 8)
Step-by-step explanation:
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is +8
Step-1 : Multiply the coefficient of the first term by the constant 1 • 8 = 8
Step-2 : Find two factors of 8 whose sum equals the coefficient of the middle term, which is -6 .
-8 + -1 = -9
-4 + -2 = -6 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and -2
x2 - 4x - 2x - 8
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-4)
Add up the last 2 terms, pulling out common factors :
2 • (x-4)
Step-5 : Add up the four terms of step 4 :
(x-2) • (x-4)
Which is the desired factorization

A firework is fired into the air from the top of a barn. Tis hight (h) above the ground in yards after (t) seconds is given by the function h(t)= -5t^2 + 10t + 20
1. At what time does the firework reach its maximum hight?
2. What is the maximum hight of the firework?
3. At what time will the firework fall to the ground?
The given function for the height of the firework is a quadratic function
1. Time at which the firework reaches the maximum height is 1 seconds
2. The maximum height of the firework, is 25 yards
3. Time after which the firework will fall to the ground is (1 + √5) seconds
Reason:
The given function that represents the height of the fireworks with time is
presented as follows;
h(t) = -5·t² + 10·t + 20
1. The time at which the firework reaches its maximum height is given by
the maximum point of the given function as follows;
The x-value of the maximum point of a quadratic function is [tex]x = \dfrac{b}{2 \cdot a}[/tex]
Where;
a, and b, are the coefficient of x² and x, in the general form of a quadratic function f(x) = a·x² + b·x + c
By comparison, we have;
[tex]t = -\dfrac{10}{2 \times (-5)} = 1[/tex]
The time at which the firework reaches the maximum height is t = 1 seconds2. The maximum height is given by plugging in the value of t, at the maximum point into the given function as follows;
h(1) = -5×1² + 10×1 + 20 = 25
The maximum height of the firework, f(1) = 25 yards3 The time at which the firework will fall to the ground, is given by the zero of the function as follows;
When the firework falls to the ground, h(t) = 0 = -5·t² + 10·t + 20
Dividing both sides by (-5) gives;
[tex]\dfrac{0}{-5} = \dfrac{ -5 \cdot t^2 + 10 \cdot t + 20}{-5} = t^2 - 2 \cdot t - 4[/tex]
t² - 2·t - 4 = 0
By the quadratic formula [tex]x = \dfrac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex], we get;
[tex]t = \dfrac{2\pm \sqrt{(-2)^{2}-4\times 1\times (-4)}}{2\times 1} = \dfrac{2\pm \sqrt{20}}{2\times 1} = \dfrac{2\pm 2 \times \sqrt{5}}{2\times 1} = 1 \pm \sqrt{5}[/tex]
Therefore;
The time after which the firework will fall to the ground, t = 1 + √5 secondsLearn more here:

Find the measure of the missing angles.
26°
yº
x°
Answer:
y = 90
x = 64
Step-by-step explanation:
y is 90 because of right angle
if add 26 + 90 = 116 -> 180 (angle of straight line) - 116 = 64 which is angle of angle to left of y and therefore x bc opposite angles equal each other
or even if you saw the line that includes x, 26, and y, x is still 64
also, the other angle that is blank should be 26+y (if our calculations are correct) so it would be 116 -> and if we add up everything we should get 360 so, x/64 + 26 + y/90 + blank angle/64 + 116 = 360 -> all correct!

3x = 2x + 16
x = 16
----------------
check
3 * 16 = 2 * 16 + 16
48 = 48
the answer is good
Answer:
x=16
Step-by-step explanation:
Since both angles are vertically opposite, there fore they equal each other.
2x + 16 = 3x
Subtract 3x from both sides
2x - 3x + 16 = 3x - 3x
-x + 16 = 0
-x = 0-16
-x = -16 (Multiply both sides by -1)
x = 16
---------
3x 16 = 48
2*16 + 16 = 48
