Answer:
a).
[tex]{ \bf{first \: term}} \\ let \: n = 1 \\ n_{1} = {1}^{2} + 3(1) + 1 \\ n_{1} = 5 \\ \\ { \bf{second \: term}} \\ let \: n = 2 \\ n_{2} = {2}^{2} + 3(2) + 1 \\ n_{2} = 11 \\ \\ { \bf{third \: term}} \\ n_{3} = {3}^{2} + 3(3) + 1 \\ n_{3} = 19 \\ \\ { \bf{fourth \: term}} \\ n_{4} = {4}^{2} + 3(4) + 1 \\ n_{4} = 29[/tex]
b).
common difference, d:
[tex]d = n_{4} - n_{3} \\ d = 29 - 19 \\ d = 10\\ but \: increases \: by \: 2 \\ d = 10 + 2 = 12\\ therefore : \\ n_{5} = n_{4} + d \\ n_{5} = 29 + 12 \\ n_{5} = 41[/tex]
c).
[tex]n_{5} = {5}^{2} + 3(5) + 1 \\ n_{5} = 41[/tex]

s= 9/4
4) 2x(x+y)-(4x+2y)(3x-y)
Answer:
-10x² + 4xy - 2y²
Step-by-step explanation:
2x(x + y) - (4x + 2y)(3x - y)
= 2x² + 2xy - 12x² - 4xy + 6xy - 2y²
= 2x² - 12x² + 2xy - 4xy + 6xy - 2y²
= -10x² + 4xy - 2y²
Help me please! Am horrible at math.
Answer:
Step-by-step explanation:
For a. the 14.7 represents the pressure that the air puts on you all the time.
For b. the d represents the depth you go under the surface of the water.
For c. we have to solve p(d) when d = 8:
p(8) = 14.7 + 0.445(8) so
p(8) = 14.7 + 3.56 and
p(8) = 18.26 psi

Which expression is equivalent to
Answer:
The second option
Step-by-step explanation:
First, simplify the bracket
[tex] \frac{4r {}^{3} s {}^{2} t {}^{4} }{2r {}^{4} st {}^{6} } [/tex]
Apply Quotient of Powers
[tex]2 {r}^{ - 1} s {t}^{ - 2} [/tex]
Which equals
[tex] \frac{2s}{rt {}^{2} } [/tex]
Raise this to the fifth power
[tex] \frac{32s {}^{5} }{ {r}^{5} t {}^{10} } [/tex]
Multiply by the outsides numbers(5^r^6 and t^4
[tex] \frac{160 {}^{} r {}^{6}s {}^{5} t {}^{4} }{r {}^{5} t {}^{10} } [/tex]
[tex]160r {}^{5} t {}^{ - 6} [/tex]

What is the solution to the equation 5 + b = 18?
F b= 5
H b= 13
Gb=8
Jb= 23
Answer:
H) B= 13
Step-by-step explanation:
5 + b = 18
F) 5 + 5 = 10 so not equal to 18. It is not a solution
H) 5 + 13 = 18 it's equal . so it is the solution
G) 5 + 8 = 13 so not equal to 18. It is not a solution
J) 5 + 23 = 28 so not equal to 18. It is not a solution
13 is the answer
Step-by-step explanation:
5+b=18
b=18-5
b=13.

What was Veronica's speed if she drove 475 miles in 6 1/4 hours?
Answer: 76 mph
Step-by-step explanation: speed is distance divided by time so 475 : 6.25 = 76 (mph)
Answer:
76 mph
Step-by-step explanation:
To find the answer, you would divide the miles she drove: 475 by the amount of time it took to get there: 6 1/4 hours. Convert the fraction to a decimal: 1/4= .25 so your problem would look like this...
475 / 6.25 = 76
Does y=-4/5x represent a direct variation is yes,identify the constant of variation
Answer:
Most likely yes... there is a problem in the way you asked your question ...
if the question is [tex]y = ( \frac{-4}{5}) x[/tex] then the answer is yes and the constant is -4/5's
If by some chance the actual question is [tex]y = \frac{-4}{(5x)}[/tex] (you can not tell by the way y0u presented tis problem.. then the answer would be NO it would be "inverse" relation

There are 31 days in August.
1/2 * 31 - 1/2 * 39
= 15 1/2 - 19 1/2
= -4.
Diana works in a building that is 130 feet tall. She is outside, looking up at the building at an angle of 37° from her feet to the top of the building.
Let x be her initial distance from the building, then tan 37 = 130/x
x = 130/ tan 37 = 130/0.7536 = 172.5 feet
Let y be her distance from the building after moving forward, then
tan 40 = 130/y
y = 130/tan 40 = 130/0.8391 = 154.9
After moving forward, she is 172.5 - 154.9 = 17.6 ft closer.
Answer:
172.5 feet to the nearest tenth.
Step-by-step explanation:
I guess you need the distance between Diana and the bottom of the building.
tan 37 = 130 / d where d is this distance
d * tan 37 = 130
d = 130 / rtan 37
= 172.5158 feet
