I don't understand this question, can you maybe reword it or make it easier to understand? There's no grammar so I can't understand.
Answer:
14, 19, 26, 7
Step-by-step explanation:
f(3) = 2(3)^2 - 3(3) + 5
f(3) = 2(9) - 9 + 5
f(3) = 18-9+5
f(3) = 14
f(-2) = 2(-2)^2 - 3(-2) + 5
f(-2) = 2(4) + 6 + 5
f(-2) = 8 + 6 + 5
f(-2) = 19
g(10) = 3(10) - 4
g(10) = 30-4
g(10) = 26
17 = 3x-4
21 = 3x
7 = x
Answer:
Width =15
Length =33
Step-by-step explanation:
Take width as x
And length as 2x+3
Perimeter as 96
Formula of the perimeter of a rectangle is 2l+2w
X+×+2×+3+2×+3=96
6x+6=96
6x=96-6
6×=90
X=15
Width =x and x =15 so width =15 while length =33
Answer:
Step-by-step explanation:
First, instead of doing 1395, let's find its coterminal angles. We can do so by subtracting 360 until we reach a solvable range. So:
This is still too high, continue to subtract:
So, instead of 1395, we can use just -45.
So, evaluate each trig function for -45:
1)
Remember that we can move the negative inside of the sine outside. So:
Remember the sine of 45 from the unit circle:
2)
Remember that we can ignore the negative inside of a cosine function. So:
Evaluate using the unit circle:
Now, remember that tangent is sine over cosine. So: "
We already know them. Substitute:
Simplify:
And we're done!
So18 is to 2 and54 is to 6
18:2 and 54:6
18/2 and 54/6
simplify
9/1 and 9/1
she is running at the same rate
so we need to do
t times something=k
its eems that she divided the time by 9
so
1/9t=k
the equation is 1/9t=k
