A house that is 30 feet tall casts a shadow that is 50 feet long. A nearby tree casts a shadow that is 75 feet long. HOW LONG IS THE TREE?
Answers
Answer:
the tree would be 45 feet tall
Step-by-step explanation:
so the house is 30 feet and 50 feet shadow, if you divide by 2 you can see that every 15 feet gives a 25 foot shadow, since 75-50 is 25 so in turn if the tree is 45 feet tall, it will make 75 foot shadow

A. Y+5=-2/5(x+3)
B. Y+5=(-2/5)x-3
C. Y-5=-2/5(x+3)
D. Y-5=-2/5(x-3
Answers
Answer:
We conclude that an equation in the point-slope form will be:
y+5 = -2/5 (x+3)
Hence, option A is true.
Step-by-step explanation:
We know that the point-slope form of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
Given
point (-3, -5)slope m = -2/5substituting the values m = -2/5 and the point (-3, -5) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
y - (-5) = -2/5 (x-(-3))
y+5 = -2/5 (x+3)
Therefore, we conclude that an equation in the point-slope form will be:
y+5 = -2/5 (x+3)
Hence, option A is true.

We choose a number from the set 1, 2, 3,..., 100 uniformly at random and denote this number by X. For each of the following choices decide whether the two events in question are independent or not.
a. A = {X is even), B-(X is divisible by 5}
b. C= (X has two digits), D = {X is divisible by 31}
c. E= {X is a prime), F = {X has a digit 5}
Answers
Answer:
(a) A and B are dependent.
(b) C and D are dependent.
(c) E and F are dependent.
Step-by-step explanation:
Two sets are said to be independent if the intersection of the two set is empty. That is the sets are disjoint.
Let's examine the situations to determine if they are independent or not.
(a) A = {2, 4, 6, . . . , 10, . . . , 20, . . .} and B = {5, 10, 15, . . . , 20, . . .}. Since A n B = {10, 20, . . .}, then the sets are dependent
(b) C = {10, 11, 12, . . . , 31, . . . , 62, . . . , 93, . . .} and D = {31, 62, 93}. Since C n D = {31, 62, 93}, then the sets are dependent.
(c) E = {5, 7, 11, . . .} and F = {5, 15, . . .}. Since E n F = {5}, then the set are dependent.
Thus
(a) A and B are dependent.
(b) C and D are dependent.
(c) E and F are dependent.
A local pizza restaurant delivery time has a uniform distribution over 10 to 75 minutes. What is the probability that the pizza delivery time is more than 30 minutes on a given day
Answers
Answer:
The probability that the pizza delivery takes more than 30 minutes is 61.53%.
Step-by-step explanation:
To determine the percentage of probability that the pizza will take more than 30 minutes to be delivered, knowing that the delivery delay time is evenly distributed between 10 and 75 minutes, the following calculation must be performed:
75 - 10 = 65
100/65 = 1.53
30 - 10 = 20
65 - 20 = 40
40 x 1.53 = 61.53
Therefore, the probability that the pizza delivery takes more than 30 minutes is 61.53%.
Answer:
0.6923
Step-by-step explanation:
we have to find P(X>45)
uniform distribution formula is P(X>A) = (b-A)/(b-a)
we have A = 30, a = 10 and b =75
P(X>45) = (75-30)/(75-10) = 45/65
P(X>45) = 0.6923

Answer:
a₁₈ = 113
Step-by-step explanation:
There is a common difference d between consecutive terms
d = 49 - 45 = 53 - 49 = 57 - 53 = 4
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference

I know there is a very similar question already out there
but my version is requesting different functions
Cami is comparing the growth rates in the value of two items in a collection. the value of a necklace increases by 3.2% per year. the value of a ring increases by 0.33% per month.
1a) Write a function to represent the value of A of the necklace after t years, assuming the initial value of $1
1b) then write an equivalent function with a power of 12t
2a) Write a function to represent the value of B of the ring after t years with the power of 12t , assuming the initial value of $1
2b) then write an equivalent function with a power of t
so
1a) A= 1 (1+3.2/100)^t
A= $1.032
1b) ????? please help
2a) B=1 (1+0.33/100)^12t
B= $1.04
2b) ???????? please help
ty ty ty this momma is trying to help her kids and is a bit lost !
Answers
Problem 1, part (a)
t = number of years
A = value of the necklace after t years
3.2% = 3.2/100 = 0.032
If the necklace starts off being $1, then after t years, it will have this value
A = 1*(1 + 0.032)^t
A = 1.032^t
You were close, but forgot about the exponent t
------------------------------------
Problem 1, part (b)
Since t represents the number of years, this means 12t represents the number of months, because there are 12 months in a year.
The annual growth rate is 3.2%, which converts to 0.032
Divide this over 12 and we get the approximate value 0.032/12 = 0.00267
So we get this new equivalent function
A = 1*(1+0.00267)^(12t)
A = 1.00267^(12t)
=========================================================
Problem 2, part (a)
t = number of years
12t = number of months
The ring's value goes at a rate of 0.33% per month, which converts to the decimal form 0.0033
The value of the ring is
B = 1*(1 + 0.0033)^(12t)
B = 1.0033^(12t)
------------------------------------
Problem 2, part (b)
We'll take the reverse approach in what we did with part (b) of the previous problem. There we divided by 12 to go from an annual rate to a monthly rate.
We'll multiply by 12 to go from the monthly growth rate to the annual growth rate.
The monthly growth rate of 0.33% turns into the annual growth rate of 12*0.33% = 3.96%, and that turns into the decimal form 0.0396
So,
B = 1*(1+0.0396)^t
B = 1.0396^t
represents the value of the ring after t years.
through: (-9, 0), perpendicular to
y = 3x - 2
In slope intercept form
Answers
Answer:
The equation perpendicular to y = 3x - 2 and passing through (-9, 0) in the slope-intercept form will be:
[tex]\:\:y\:=-\frac{1}{3}x-3[/tex]Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the line
y = 3x - 2
comparing with the slope-intercept form of the line equation
The slope of the line y = 3x - 2 is: m = 3
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = 3
Thus, the slope of the the new perpendicular line = – 1/m = -1/3 = -1/3
The point-slope form of the line equation is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointIn our case:
m = -1/3(x₁, y₁) = (-9, 0)now substituting the perpendicular slope m = -1/3 and (-9, 0) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-0=-\frac{1}{3}\left(x-\left(-9\right)\right)[/tex]
[tex]y=-\frac{1}{3}\left(x-\left(-9\right)\right)[/tex]
[tex]y=-\frac{1}{3}\left(x+9\right)[/tex]
[tex]\:\:y\:=-\frac{1}{3}x-3[/tex]
Therefore, the equation perpendicular to y = 3x - 2 and passing through (-9, 0) in the slope-intercept form will be:

Answer:
The slope is 5
Step-by-step explanation:
divide the change in y by the change in y
you can use two different points for example 1,5 and 3,15
the change in y between these points is 10, the change in x is 2
10/2=5
also since the values of x increase constantly by 1 and it's a continuous line (meaning the domain could be any number between 1 and 3 in this graph) you can calculate only the change in y and that will give you the slope

Answers
Answer:
Anthony needs to invest $99.33.
Step-by-step explanation:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Interest rate of 2.7% compounded quarterly.
This means that [tex]r = 0.027, n = 4[/tex].
How much would Anthony need to invest, to the nearest hundred dollars, for the value of the account to reach $130 in 10 years?
We have to find P for which: [tex]A = 130, t = 10[/tex]. So
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]130 = P(1 + \frac{0.027}{4})^{4*10}[/tex]
[tex]P = \frac{130}{(1 + \frac{0.027}{4})^{4*10}}[/tex]
[tex]P = 99.33[/tex]
Anthony needs to invest $99.33.
