Answer:
I believe your answer would be -5 because in the first part of the question, it tells you that ground level is 0. (by saying that when you go up 10 from ground level, you are at postitive (+)10)
so... if you go 5 down from ground level (0), it the same as 0-5 which is -5. hope this helps! :)
Step-by-step explanation:
The value of y varies directly with x. When y = 75,x= 2. What is the value of y when
xis 2 1/4
Answer:
y = 337.5
Step-by-step explanation:
Given:
y = 75
x = 2
Solve:
Direct variation is y = kx
75 = k/2
k = 150
y = 150x
x = 2 1/4 or 2.25
y = 150(2.25)
y = 337.5 or 337 1/2

Answer:
1. r = [tex]\sqrt[3]{\frac{3v}{4\pi } }[/tex]
divide v by 4/3, this is the same as multiplying v by 3/4 so you have 3v/4
then divide v by [tex]\pi[/tex] so you now have 3v/4[tex]\pi[/tex]
then get rid of the ^3 on r by putting the solution for r under a ∛
2. a) The equation might need to be written in terms of a because you may not know the value of a, but you know the value of everything else. If this is the case then you can simply rewrite the equation so that you can plug it all into a calculator and avoid certain possible errors.
b)
s = ut + 1/2 [tex]at^{2}[/tex]
subtract ut from both sides: s - ut = 1/2 [tex]at^{2}[/tex]
multiply both sides by 2: 2(s - ut)
divide both sides by [tex]t^{2}[/tex]: [tex]\frac{2(s - ut) }{t^{2} }[/tex] = a
answer: a = [tex]\frac{2(s - ut) }{t^{2} }[/tex]
I'm not entirely sure about b) for question 2 so you might wanna double check that with a friend

50 POINTSSS Let f (2) represent a function.
Which descriptions match the given transformations?
Drag and drop the answers into the boxes.
For f(x - 3.5) the answer is that f(x) is translated 3.5 units right
You can figure that out by thinking that for x = 3.5 (which is 3.5 units to the right of x = 0, f(3.5 - 3.5) is the same that f(0), ... for x = 10.5 (which is 3.5 units to the right of x = 7, f(10.5 - 3.5) = f(7) ... and so for every value of x.
For 3.5 f(x) the answer is that f(x) is vertically stretched by a factor of 3.5 which you figure out from a table like this:
f(x) 3.5 f(x)
0 0
1 3.5
2 7
10 35
And from that you can see the 3.5 f(x) is horizontally compressed and vertically stretched respect to f(x).
If f(x)=x2+3x−2, find f(−2).

At the grocery store, 6 pints of ice cream cost $8.94. How much would 35 pints of ice cream cost?
Answer:
52.15
Step-by-step explanation:
you need to find how much each pint cost by itself so...
8.94 divided by 6 is 1.49
then 1.49 x 35 = 52.15
and that is your answer
Answer:
$52.15
Step-by-step explanation:
i just dived 8.94 by 6 then multiplyed that answer by 35

ort each equation according to whether it has one solution, infinitely many solutions, or no solution
-3(X - 4) = – 3x + 12
4(x + 1) = 3x + 4
-2(x-3) = 2x - 6
6(x + 5) = 6x + 11
5(x-2)=5x-7
-3(X - 4) = – 3x + 12 infinite solutions
4(x + 1) = 3x + 4 one solution
-2(x-3) = 2x - 6 one solution
6(x + 5) = 6x + 11 no solution
5(x-2)=5x-7 no solution

Please help me!!
Answer:
x=8
Step-by-step explanation:
bc (8-7) =1, 1 time 4 = 4 (we always do -/+ before multiplication)
and (10-8)=2, 2 time 2 = 4
since for both you get the same result therefore x=8

a train travelling at 60 km per hour completes the journey in 8 hour. How much faster would it have to travel to cover the same distance in 6 hour
Answer:
Total distance covered: 60x8 = 480
Speed needed to cover distance of 480 km in 6 hrs = 480/6 = 80 km/hr.
initial velocity : 60 km/hr.
Train needs to run faster with speed of 20km per hour to achieve same distance in 6 hrs.

The graph shows a function
Answer:
E, D
Step-by-step explanation:
rate of change is the slope
slope is change in y over change in x
the slope of the graph is (3/2)
E has a slope of 1/2 which is less than 3/2
D has a slope of 1 which is also less than 3/2
11-17
1. A student finds the slope of the line between (14, 1) and (18. 17). She writes 18 - 14
What mistake did she make?
A She should have added the values, not subtracted them.
B She used y-values where she should have used x-values,
C She mixed up the x- and y-values.
D She did not keep the order of the points the same in numerator and the denominator
A
B
c
The answer is D.
It should be 17 -1 / 18 -14

complete the square for the expression, then factor the trinomial.
x^2-4x
please explain how to do it as well! :)
Answer:
Completing the square we get: [tex](x-2)^2-(2)^2[/tex]
and factoring the term we get: [tex]x(x-4)[/tex]
Step-by-step explanation:
We need to complete the square for the expression [tex]x^2-4x[/tex]
For completing the square the expression would be of form [tex]a^2+2ab+b^2=(a+b)^2[/tex]
For given expression we have to add (2)^2 and subtract to make it complete the square.
[tex]x^2-2(x)(2)+(2)^2-(2)^2\\(x-2)^2-(2)^2[/tex]
Now, we have to factor the polynomial using formula [tex](a)^2-(b)^2=(a-b)(a+b)[/tex]
So, [tex](x-2)^2-(2)^2\\=(x-2-2)(x-2+2)\\=(x-4)(x-0)\\=x(x-4)[/tex]
Completing the square we get: [tex](x-2)^2-(2)^2[/tex]
and factoring the term we get: [tex]x(x-4)[/tex]
