What is the distance between the points (22, 27) and
(2,-10)? If necessary, round your answer to two decimal
places.
Answer:
d = 42.06
Step-by-step explanation:
d=(2−22)2+(−10−27)2−−−−−−−−−−−−−−−−−−−√
d=(−20)2+(−37)2−−−−−−−−−−−−−√
d=400+1369−−−−−−−−−√
d=1–√769
d=42.059482

Answer:
0.6t - 4.3s - 2.6.
Step-by-step explanation:
PEMDAS
Answer:
-4.3s+0.6t-2.6
Step-by-step explanation:
Add like terms:
-3.5t+4.1t-4s-0.3s+4.5-7.1
= 0.6t-4.3s-2.6
= -4.3s+0.6t-2.6

Use the ratio test to determine whether the series is convergent or divergent.2 +4/2^2 + 8/3^2 + 16/4^2 +
Answer:
The result is 2 > 1. Hence, the series diverges
Step-by-step explanation:
You have the following series:
[tex]2+\frac{4}{2^2}+\frac{8}{3^2}+\frac{16}{4^2}+...+\frac{2^n}{n^2}=\sum_{i=1}^{i=n}a_n[/tex] (1)
You use the ratio test to determine if the series is convergent or divergent. The ratios test is given by:
[tex]\lim_{n \to \infty} \frac{a_{n+1}}{a_n}[/tex] (2)
Then, you replace the series (1) in (2):
[tex]\lim_{n \to \infty} \frac{\frac{2^{n+1}}{(n+1)^2}}{\frac{2^n}{n^2}}= \lim_{n \to \infty} \frac{(2^n2)(n^2)}{2^n(n+1)^2}\\\\\lim_{n \to \infty} \frac{2n^2}{n^2+2n+1}= \lim_{n \to \infty} \frac{2n^2}{n^2[1+\frac{2}{n}+\frac{1}{n^2}]} \\\\\lim_{n \to \infty} \frac{2}{1+\frac{2}{n}+\frac{1}{n^2}}=\frac{2}{1+0+0}=2[/tex]
In the ratio test you have that if the limit is greater than 1, the series diverges.
The result is 2 > 1. Hence, the series diverges.

WILL MARK BRAINLIEST! If you buy 3 pounds of hamburg for $8.97, how much will it cost for 5 pounds of hamburg?
Answer:
14.95
Step-by-step explanation:
every 1 pound is 2.99 so you would do 2.99 * 5
Answer:
$14.95
Step-by-step explanation:
To find the slope or the cost per pound of hamburger you divide 8.97 by 5 in order to find out it costs 2.99 per hamburger. You then, multiply 2.99 by 5 to gather that to buy 5 pounds of hamburger it would cost $14.95.
A 10-foot ladder is to be placed Against the side of the building. The base of the latter must be placed in an angle of 72° With the level ground for a secure footing. Find, to the nearest inch, how far the base of the latter should be from the side of the building and how far up the side of the building the latter will reach.
Answer:
Distance of foot of ladder from building: 37.2 inches
Distance of top of ladder from building's base: 114 inches
Step-by-step explanation:
Please refer to the figure attached in the answer area.
A right angled triangle [tex]\triangle ABC[/tex] is formed by the ladder with the building where hypotenuse is the length of ladder.
Hypotenuse, AC = 10 foot
Also, we are given that angle made by the base of ladder with the ground is [tex]72^\circ[/tex].
We have to find AB and BC.
[tex]\angle BAC = 72^\circ[/tex]
Using trigonometric functions:
[tex]cos \theta= \dfrac{Base}{Hypotenuse}\\cos 72^\circ= \dfrac{AB}{AC}\\\Rightarrow 0.309 = \dfrac{AB}{AC}\\\Rightarrow AB = 10 \times 0.309\\$\approx$ 3.1 foot\\$\approx$ 37.2 inches[/tex]
[tex]sin \theta = \dfrac{Perpendicular}{Hypotenuse}\\\Rightarrow sin72^\circ = \dfrac{BC}{AC}\\\Rightarrow 0.95 = \dfrac{BC}{AC}\\\Rightarrow AB = 10 \times 0.95\\$\approx$ 9.5 foot\\$\approx$ 114 inches[/tex]
Distance of foot of ladder from building: 37.2 inches
Distance of top of ladder from building's base: 114 inches

Answer:
(-1, -2.5)
Step-by-step explanation:
The midpoint formula is just basicallyadding both of the x values and then dividing the sum of them by 2, after that you will be adding both y values and then dividing them by 2, then you will get the midpoint x and y coordinate values. You can look up midpoint formula on google to see how it's actually written. You have to make sure to add correctly when you are using the negative numbers, because they can actually turn the equations into subtraction. Keep in mind, it can beconfusing sometimes when you are working with positive and negative numbers together. So make sure to just double check your work and also to make sure you added correctly.

What is the area of this triangle?
A. 12 square centimeters
B. 36 square centimeters
C. 16 square centimeters
D. 18 square centimeters
Answer:
A is the correct answer.
Step-by-step explanation:
The formula for the area of a triangle is A = 1/2 b x h
The base in this triangle is 6 and the height is 4 so 6 x 4 = 24.
Now we divide 24 by 2 which gives us 12 square centimeters.
Hope this helps
Answer: A. 12 square centimeters
Step-by-step explanation:
The area of a triangle is (1/2)bh because any triangle is half of a square (square formula = bh).
1/2bh --> 1/2 * 6 * 4 --> 12 square centimeters
Hope this helps! Good Luck :)

Answer:
Mean = [26 + 31 + 39 + 32]/4 = 32
MAD = (1/4) x [|26 - 32| + |31 - 32| + |32 - 32| + |39 - 32|] = (1/4) x 14 = 3.5
Hope this helps!
:)
Answer:
3.5 putts
Step-by-step explanation:
Mean: 26 + 31 + 32 + 39 = 128/4 = 32
32 - 26 = 6
32 - 31 = 1
32 - 32 = 0
32 - 39 = 7
Mean Absolute Deviation (MAD): 6 + 1 + 0 + 7 = 14/4 = 3.5

5(7 + 3x) - 12 how to simplify
To solve this we need to use this formula:
a(b+c)=ab+ac
5(7+3x)-12=35+15x-12=15x+23
Answer:
Step-by-step explanation:
Multiply the 5 to the 7 and 3x--> 35 + 15x -12. Then add 12 to the -12, making it 0 (inverse operations), and add 12 to the 35 making it 47 + 15x. :) Then you would simply divide the 15 by 15x (making the variable by itself). your answer for x should be 47/15. :> If I helped, please mark brainliest!!
The sale price of a drum kit in the UK is 950 Pounds + VAT (Value Added Tax), where VAT is a sales tax of 20%. After some negotiation, the owner of the store agrees to give Bob a 12% discount on the drum kit. What is the total price that Bob pays, including VAT? Answer in Pounds and round your answer to the nearest pence (1 pence=1100Pound).
Note: VAT is a sales tax that gets calculated before a discount is applied.
Answer:
Step-by-step explanation:
Sale price = 950 pounds + vat
Vat = 20%
Value vat = 20/10 × 950 = 190 pounds.
Since the vat is calculated before a discount is applied, it means that the amount on which the discount was applied is
950 pounds
The value of the discount would be
12/100 × 950 = 114 pounds
The amount to be paid including vat is
(950 - 114) + 190 = 1026 pounds
Two interior angles of a triangle each measure 34°. What is the measure of the third interior angle?
A. 146°
B. 292°
C. 56°
D. 112°
Answer:
D. 112
Step-by-step explanation:
Since we know that a triangle totals 180 degrees, we can easily figure out the third angle. Since each measure 34 degrees, simply multiply by 2. You get 68 degrees. Then you do 180-68 to get 112.
