Answer:
C. 215.12 feet per second
Step-by-step explanation:
Sergei's car was clocked in a quarter mile race at 146.67 miles per hour.
How many feet per second is this to the nearest hundredth if there are 5280 feet in one mile?
From the above question
1 mile = 5280 feet
1 hour = 60 minutes
1 minutes = 60 seconds
1 hour = 60 × 60 seconds = 3600 seconds
We are to convert 146.67 miles per hour = feet per second
Hence:
146.67 miles /1 ft × 5280 feet/1 miles × 1 hr/3600 seconds
= 146.67 × 5280 feet/3600 seconds
= 774417.6 feet / 3600 seconds
= 215.116 feet per second.
Approximately = 215.12 feet per second

Given a right triangle with leg lengths f and g, and hypotenuse h, if f = 7 cm and h = 11.2 cm, what is g?
Show your work.
Step-by-step explanation:
o2+a2=h2
100} h^{2}=(10ft)^{2} +(17ft)^{2}
h2=100ft2+289ft2
h=389ft2−−−−−√
→19.7ft
this is an example on how to do it
The value of g in the given right triangle is 13.20 units.
What is the Pythagoras theorem?Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse.
Given that, a right triangle with leg lengths f and g, and hypotenuse h, if f = 7 cm and h = 11.2 cm,
We need to find the value of g the hypotenuse,
So, here using the Pythagoras theorem,
f²+h² = g²
Therefore,
11.2²+7² = g²
g² = 174.44
g = 13.20
Hence, the value of g in the given right triangle is 13.20 units.

Find the common ratio of the geometric sequence -13, 39, -117
Answer:
-3
Step-by-step explanation:
you can divide the second term by the first term to solve
39/-13 = -3
then, I like to check that this fits with the third term
39*-3 = -117
so the common ratio is -3
I got three questions that need to be answered.
For questions 1-3, solve for x. Round your answer to the nearest tenth.
Answer:
1.)x=15.9
2.)x=17.49
3.) x=7.29
Step-by-step explanation:
For all the questions use Pythagorean Theorem which is [tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex]
C=opposite of hypotenuse
A=Leg
B=Leg
1.) [tex]6^{2}[/tex]+[tex]b^{2}[/tex]=[tex]17^{2}[/tex]
Simplify the equation
36+[tex]b^{2}[/tex]= 289
Subtract 36 from both sides
[tex]b^{2}[/tex]=289
Square Root both sides to equal 15.9
Do the same for questions 2-3
Hope this helps! :)

Write a polynomial function of least degree with rational coefficients so that P(x)0 has the given roots. x=-5, x=10
Answer:
P(x) = x² - 15x + 50
Step-by-step explanation:
We write the polynomial function P(x), given that P(x) = 0 has the given roots, x = 5 and x = 10.
Since x = 5 and x = 10 are the roots of P(x) = 0, it follows that (x - 5) and (x - 10) are factors of P(x) = 0. So, P(x) = (x -5)(x - 10) = 0
Expanding the brackets, we have
x² - 10x - 5x + 50 = 0
Simplifying, we have
x² - 15x + 50 = 0 = P(x)
Thus,
P(x) = x² - 15x + 50

Which is cheaper if you want to buy 7 boba drinks? How much cheaper? What is the solution to the system of equation?
Answer:
Boba Club is cheaper if you want to buy 7 Boba drinks. It's cheaper by 3.
Step-by-step explanation:
Boba Club: y=2x+4
Jack's Boba: y=3x
Replace the X variable with 7 for both equations. For Boba Club, multiply 2 by seven to get 14, then add four to get 18. For Jack's Boba, multiply 3 and 7 to get 21. Boba Club is cheaper. (What would you need 7 Boba drinks for though?)

Answer:
(x -2)² +(y -4)² = 25
Step-by-step explanation:
The area of a square is half the product of the diagonals, so that product is 50·2 = 100. This is the square of the diameter, so the square of the radius is 100/4 = 25. Then the circle equation is ...
(x -h)² +(y -k)² = r² . . . . . . . circle with center (h, k) and radius r
