By definition of exponential function, The function y = (1/5)ˣ is an exponential decay.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
We have to given that;
The function is,
⇒ y = (1/5)ˣ
Now, We have;
The general form of the exponential function is,
⇒ y = a bˣ
If b < 1 , function is an exponential decay.
If b > 1, function is an exponential growth.
Here, The function is,
⇒ y = (1/5)ˣ
And, b = 1/5 < 1
Hence, By definition of exponential function, The function y = (1/5)ˣ is an exponential decay.
Therefore, By definition of exponential function, The function y = (1/5)ˣ is an ''exponential decay.''

Find the lateral surface area of a triangular prism with height of 6 inches and right triangles bases with legs 9 inches and 12 inches
Given:
Height of a triangular prism = 6 inches
Legs of right triangular base are 9 inches and 12 inches.
To find:
The lateral surface area of a triangular prism.
Solution:
According to the Pythagoras theorem:
[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]
Using Pythagoras theorem, we get
[tex]Hypotenuse^2=(9)^2+(12)^2[/tex]
[tex]Hypotenuse^2=81+144[/tex]
[tex]Hypotenuse^2=225[/tex]
Taking square root on both sides, we get
[tex]Hypotenuse=\sqrt{225}[/tex]
[tex]Hypotenuse=15[/tex]
Now, the lateral surface area of a triangular prism.
[tex]A=Ph[/tex]
Where, P is the perimeter of the base and h is the height of the prism.
[tex]A=(9+12+15)\times 6[/tex]
[tex]A=(36)\times 6[/tex]
[tex]A=216[/tex]
Therefore, the lateral surface area of a triangular prism is 216 square inches.

Answer:
here is the link the.hh/g49
Step-by-step explanation:
Answer:
q = 45
Step-by-step explanation:
Since q is 30 when p is 6, we divide to find the rate.
30/6=5.
If the rate is 5 we multiply the new p, 9 by five as well.
9*5=45
45 is q ok

if one zero of the following polynomial 8x^2-13x-4k is the reciprocal of the other, then find k
Answer:
Step-by-step explanation:
hello :
if x1 and x2 this zero for ax²+bx+c you have : x1 = 1 /x2 means :x1 × x2 =1
but : x1 × x2 = c /a
in this exercice : a =8 and b = -13 and c = - 4k
so : c/a =-4k/8
so : -4k/8 = 1
-4k = 8 k = 8/-4 k = -2
this polynomial is : 8x²-13x +8

hope i helped
Answer:
16.3 feet
Step-by-step explanation:
find the value of the missing side using the pythagorean theorem -
[tex]a^{2} + b^{2} = c^{2}[/tex] -> [tex]3^{2} +a^{2} =7^{2}[/tex] -> 9 + [tex]a^{2}[/tex] = 49 -> [tex]a^{2}[/tex] = 40 -> take the square root of both sides: [tex]\sqrt{a} = \sqrt{40}[/tex] -> a = 6.3
then you add it with the other two sides to get the perimeter: 6.3 + 3 + 7 = 16.3
Alex played basketball 20 minutes longer on Tuesday than she did on Monday. She played for a total of 110 minutes for both days. Which equation can be used to find the number of minutes Alex played on Monday?
Answer: The equation to find the number of minutes Alex played on Monday is x+(x+20) = 110 minutes
Step-by-step explanation:
let the time played by Alex on Monday be represented as x
and the time played by Alex on Tuesday be represented as x+20
Such that the expression to find out the minutes Alex played on Monday given that the total time spent on both days = 110 minutes
Monday +Tuesday = 110 minutes
x+(x+20) = 110 minutes
Solving
x+(x+20) = 110 minutes
2x+20= 110 minutes
2x = 110-20
2x =90
x=90/2=45
x= Amount of time played on Monday =45minutes
x+20 Amount of time played on Tuesday =45 +20= 65 minutes

Step-by-step explanation:
subtract 15 minutes from the time she arrives.
you get 8: 05 a.m. the distance from home to school is 12 minutes to reach at 8:0 5 subtract 12 minutes to know what time she'll leave...
if you remove 12 minutes from 8 or 5 a.m. get 7:53 a.m.

This is your chance to demonstrate your basketball skills! You have been chosen to participate in a paper-ball throwing contest. Directions: 1. Use the scrap paper to make 10 paper balls per group. (Wad the paper balls up tightly so they are easier to aim.) 2. Place a trash can (or other large container) 5 feet away. 3. Predict how many paper balls you will be able to get into the basket. Type your prediction. 4. Type your results as a fraction. 5. Type your results as a decimal.
Answer:
I Predict I can make all 10/10 paper balls into the trash can.
Step-by-step explanation:
Sadly, I was wrong, I only got 8 paper balls into the trash can...Its not my fault though, my cat kept attacking my midair balls, anyway I got 8/10 which means I got 80 percent which means I got...move decimal one left...I got (in decimal) .8 (I'm ticked that I missed any cat or no cat, My fav sport is basketball and usually in really good with my shots)

Step-by-step explanation:
Form a third-degree polynomial function with real coefficients, with leading coefficient 1, such that - 2 + i and 7 are zeros.
In standard form, this third-order polynomial - call it p(x) - has real coefficients a, b, c, d so that it is written as
p(x) = a x ³ + b x ² + c x + d
We're told the leading coefficient is a = 1, so
p(x) = x ³ + b x ² + c x + d
Since the coefficients are all real, any complex roots with non-zero imaginary part occurs alongside its complex conjugate, so the fact that -2 + i is a root means that its conjugate, -2 - i is also a root.
Then by the factor theorem, we can write p(x) as the product of linear terms involving its roots:
p(x) = (x - (-2 + i )) (x - (-2 - i )) (x - 7)
Now just expand this to get
p(x) = x ³ - 3 x ² - 23 x - 35

A circle has a diameter of 42 inches. What is the circumference of the circle? Use 227 for π.
Answer:
132 in = C
Step-by-step explanation:
Please, write 22/7 to approximate π.
The circumference formula is C = 2πr or dπ, and here C = (42 in)π
Then an approximation to the circumference of this circle is
42(22/7) = 6(22 in) = 132 in = C

The distribution of the number of children per family in the United States is strongly skewed right with a mean of 2.5 children per family and a standard deviation of 1.3 children per family.
a) Without doing any calculations, which event is more likely? Explain.
Event A: Randomly selecting a family from the United States that has 3 or more children.
Event B: Randomly selecting 40 families from the United States and finding an average of 3 or more children.
b) The probability of one of the two events listed in part (a) can be calculated even though the distribution of the population is strongly skewed right. For which event can the probability be calculated? Explain.
c) Calculate the probability of the event that you selected in part (b).
Answer:
Step-by-step explanation:
a) Which one is more likely? Explain.
Event A: Randomly selecting a family from the United States that has 3 or more children.
Event B: Randomly selecting 40 families from the United States and finding an average of 3 or more children.
Because the distribution is strongly skewed right, it means families are likely to have more than the mean, 2.5 children. So the probability is high that a randomly selected family will have 3 or more children. But the probability is even higher when 40 families are randomly selected because with a sample size of 40, the results are more likely to follow the main distribution than with a sample size of 1.
For b), because Event B has a larger sample size, its probability can be calculated. With a sample size of 1, it cannot be calculated.
Answer:
Step-by-step explanation:
a. as distribution of number of children per family in the United States is strongly skewed right with a mean of 2.5 children per family and a standard deviation of 1.3 children per family, it is likely that a randomly selecting a family from the United States has 3 or more children.
but if the sample size is increased from a family to 40 families, then it is even more likely because a larger size sample is more likely to follow the distribution. so Event B is more likely
b. Event B's probability calculation requires the right skewness and hence cant be done. but Event A, because its a single family, can be done w/ the mean n SD.
An alrcraft factory manufactures airplane engines. The unit cost C (the cost in dollars to make each airplane engine) depends on the number of engines made. If
x engines are made, then the unit cost is given by the function C(x)=0.9x - 306x +36,001. What is the minimum unit cost?
Do not round your answer.
C(x) should be ;
C(x)=0.9x² - 306x +36,001
Answer:
$9991
Step-by-step explanation:
Given :
C(x)=0.9x^2 - 306x +36,001
To obtain minimum cost :
Cost is minimum when, C'(x) = 0
C'(x) = 2(0.9x) - 306 = 0
C'(x) = 1.8x - 306 = 0
1.8x - 306 = 0
1.8x = 306
x = 306 / 1.8
x = 170
Hence, put x = 170 in C(x)=0.9x²- 306x +36,001 to obtain the
C(170) = 0.9(170^2) - 306(170) + 36001
C(170) = 26010 - 52020 + 36001
= 9991
Minimum unit cost = 9991
