Find cos(a) in the triangle.
Answer:
cos(α) = 24/25.
Step-by-step explanation:
First of all, we'll find the answer just using the fact that ABC is a right triangle in C. So, by the definition of cosine:
[tex]\cos(\alpha) = \dfrac{AC}{AB}\\\\\boxed{\cos(\alpha) = \dfrac{24}{25}}[/tex]
Now, we'll solve the question with another approach. By the Law of Cosines in the triangle ABC:
[tex]BC^2 = AB^2+AC^2-2\cdot AB\cdot AC\cos(\alpha)\\\\7^2 = 25^2+24^2-2\cdot 25\cdot 24\cos(\alpha)\\\\49 = 625+576-1200\cos(\alpha)\\\\1200\cos(\alpha)=1152\\\\\boxed{\cos(\alpha) = \dfrac{24}{25}}[/tex]

if it cost $5980 to have a picket fence installed around a rectangular lot that is 110 ft by 150 ft how much will it cost to have a picket fence installed around a rectangular light that is 125 ft by 170 ft
Answer:
6785 dollars
Step-by-step explanation:
It cost 5980 dollars for a rectangular lot that is 110 ft by 150 ft. 110 + 150 = 260. 5980/260=23. 125 + 170= 295. 295 x 23= 6785.

Answer:
32 and 5n + 2
Step-by-step explanation:
(a)
The pattern of the number of sticks is
7, 12, 17
There is a common difference of 5 between consecutive terms.
Thus to obtain the number of sticks in number 6 , add 5 to previous terms, that is
a₄ = 17 + 5 = 22
a₅ = 22 + 5 = 27
a₆ = 27 + 5 = 32
There are 32 sticks in pattern number 6
(b)
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
Here a₁ = 7 and d = 5 , then
[tex]a_{n}[/tex] = 7 + 5(n - 1) = 7 + 5n - 5 = 5n + 2
number of sticks in pattern number n is 5n + 2

An operations analyst counted the number of arrivals per minute at an ATM in each of 30 randomly chosen minutes. The results were: 0, 3, 3, 2, 1, 0, 1, 0, 0, 1, 1, 1, 2, 1, 0, 1, 0, 1, 2, 1, 1, 2, 1, 0, 1, 2, 0, 1, 0, 1. For the Poisson goodness-of-fit test, what is the expected frequency of the data value X
Step-by-step explanation:
since Poisson distribution parameter is not given so we have to estimate it from the sample data. The average number of of arrivals per minute at an ATM is
[tex]\hat{\lambda}=\bar{x}=\frac{\sum x}{n}=\frac{30}{30}=1[/tex]
So probabaility for [tex]\mathrm{X}=1[/tex] is
[tex]P(X=1)=\frac{e^{-\lambda} \lambda^{x}}{x !}=\frac{e^{-1} \cdot 1^{1}}{1 !}=0.3679[/tex]
So expected frequency for [tex]X=1[/tex] is [tex]0.3679^{*} 30=11.037[/tex] (or [tex]\left.11.04\right)[/tex] .
Aaron’s boat travels 9 mile per hour in still water. The speed of the river is 4 miles per hour. How long will it take Aaron to travel 18 miles downstream
Answer:
who will answer??
Step-by-step explanation:
It will take Aaron 1.38 hours to travel 18 miles downstream as per time distance calculation.
What is time and distance calculation?"To work out speed, divide the distance of the journey by the time it took to travel, so speed = distance divided by time. To calculate time, divide distance by speed. To get the distance, multiply speed by time.
You may see these equations simplified as s=d/t, where s is speed, d is distance, and t is time."
Given, speed of Aaron's boat is 9 miles per hour.
Speed of the river is 4 miles per hour.
Therefore, speed of Aaron's boat downstream is
= (9 + 4) miles per hour = 13 miles per hour.
Therefore, in order to travel 18 miles downstream Aaron will need
= [tex]\frac{18}{13}[/tex] hours = 1.38 hours.

Answer:
B. 1/3
Because if you focus on one point of each image you have (0,3) and (0,9). Since (0,9) is the original picture we have to find how (0,3) is related to (0,9). So 3÷9= 1/3 and that's your answer (sorry for not explaining clearly)

Step-by-step explanation:
No. of planters = 4 ÷ [tex]\frac{1}{3}[/tex]
To change the ÷ sign to a × sign, swap the denominators and numerators of the second fraction.
4 ÷ [tex]\frac{1}{3}[/tex] = 4 × [tex]\frac{3}{1}[/tex]
Directly multiply.
4 × [tex]\frac{3}{1}[/tex] = 12

Simplify this expression: -2.15m + 6 + 10.3m
Answer:
8.15m + 6
Step-by-step explanation:
To simplify, combine like terms. The only like terms here are the -2.15m and 10.3m because they both have a variable next to them.
Add the numbers together and leave the variable the same.
-2.15m+10.3m = 8.15m
Answer:
8.15m + 6
Step-by-step explanation:
-2.15m + 6 + 10.3m
combine like terms: -2.15 + 10.3 = 8.15
8.15m + 6

Given: 3j+k/2=15-4k; Prove j=10-3k
And Given 5x-2y=x+14; Prove y=2x-7
Answer:
[tex]j=10-3k[/tex]
[tex]y = 2x - 7[/tex]
Step-by-step explanation:
Solving (a):
Given
[tex]\frac{3j + k}{2}=15-4k[/tex]
Required: Prove [tex]j=10-3k[/tex]
[tex]\frac{3j + k}{2}=15-4k[/tex]
Multiply through by 2
[tex]2 * \frac{3j + k}{2}=(15-4k) * 2[/tex]
[tex]3j + k = 30 - 8k[/tex]
Subtract k from both sides
[tex]3j = 30 - 9k[/tex]
Divide through by 3
[tex]j = \frac{30 - 9k}{3}[/tex]
j = 10 - 3k
Solving (b):
Given
[tex]5x - 2y = x+ 14[/tex]
Required
Prove: [tex]y = 2x - 7[/tex]
[tex]5x - 2y = x+ 14[/tex]
Subtract 5x from both sides
[tex]-2y = x - 5x + 14[/tex]
[tex]-2y = -4x + 14[/tex]
Divide through by -2
[tex]\frac{-2y}{-2} = \frac{-4x}{-2} + \frac{14}{-2}[/tex]
[tex]y = 2x - 7[/tex]

Answer:
m = 3/2
b = 0
y = 3/2x
Step-by-step explanation:
M is the slope, which is the rise/run of a line.
Using this, we know m is 3/2.
B is the y-intercept, which is where the line crosses the y-axis. In this case, B equals 0.
We use this information to put together our final equation of y= 3/2x (since B equals 0, there is no + or - after the slope)
