Sara bought shoes for $39.95 and x pairs of socks for $1.99 each. Which expression shows the total money spent?
Answers
Answer:
$39.95 + $1.99x
Step-by-step explanation:
Cost of shoes = $39.95
Cost per pair of socks = $1.99
Number of socks pairs purchased = x
Total amout spent = (cost of shoes + cost of x pairs of socks)
Cost of x pairs of socks = $1.99 * x = $1.99x
Total amount spent = $39.95 + $1.99x
Answer:
$39.95 + $1.99x

Find the area enclosed by the x-axis and the curve x = 4 + et, y = t − t2.
Answers
Find where the curve intersects the x-axis; this happens when y = 0:
y = t - t ² = 0 → t (1 - t ) = 0 → t = 0, t = 1
Then the area of the bounded region is
[tex]\displaystyle\int_0^1 y(t) x'(t)\,\mathrm dt=\int_0^1 (t-t^2)e^t\,\mathrm dt=\boxed{3-e}[/tex]

Find the solution to the following system. Explain how you got your
answer, step-by-step.
3x + 4y = 36
y=-1/2x+8
Answers
Answer:
(x,y)=(4,6)
Step-by-step explanation:
3x+4y=36
y=-1/2 x+8
step 1: substitute the value of y
[tex]3x+4(-\frac{1}{2}x+8)=36[/tex]
step 2: solve equation for x
[tex]3x+4(-\frac{1}{2}x+8)=36[/tex]
3x-2x+32=36
x+32=36
x=36-32
x=4
step 3: substitute the value of x
[tex]y=-\frac{1}{2} (4)+8[/tex]
Step 4: solve equation for y
[tex]y=-\frac{1}{2} (4)+8[/tex]
y=-2+8
y=6
there for the answer is
(x,y)=(4,6)

A larger number is double the sum of 3 and a smaller number. The larger number is 2 less than 3 times the smaller number. If y represents the larger number and x represents the smaller number, which equations model the situation? Check all that apply.
Answers
Answer:
y = 3x - 2
3x - y = 2
y = 2(x + 3)
Step-by-step explanation:
y = the larger number
x = the smaller number
A larger number is double the sum of 3 and a smaller number
y = 2(x + 3)
y = 6 + 2x
The larger number is 2 less than 3 times the smaller number.
y = 3x - 2
Make -2 the subject
y - 3x = -2
Make 2 the subject
y = 3x - 2
y - 3x = -2
(y - 3x) * -1 = -2 * -1
-y + 3x = 2
3x - y = 2
The answers:
y = 3x - 2
3x - y = 2
y = 2(x + 3)

9. Given one of the root of the quadratic equation x^2 - 5kx+ k=0 is four times the other root, find the value of k
Answers
Answer:
k=1/4
Step-by-step explanation:
x² - 5kx+ k=0 ....(1)
suppose 2 roots: a and 4a
(x-a)(x-4a)=0
x² - 5ax + 4a² = 0 ....(2)
compare (1) and (2): -5a = -5k a=k
4a² = k 4a² = a (substitute)
a(4a-1) = 0
a = 0 or a = 1/4 (if a=0 k=0 and x=0 is not the solution)
a = 1/4 k = 1/4
(a₂ = 1/4 * 4 = 1)
Answer:
k = 1/4.
Step-by-step explanation:
Let the roots be r and 4r and using the fact that sum of the roots = -b/a and product = a/c, we have:
r + 4r = -(-5k)
r*4r = k
5r = 5k
4r^2 = k
From the 3rd equation:
r = k, therefore:
4k^2 = k
4k = 1
k = 1/4.

The drop that rider's experience on Dr. Doom's Free Fall can be modeled by the quadratic function LaTeX: h\left(t\right)=-9.8t^2-5t+39h ( t ) = − 9.8 t 2 − 5 t + 39 where h is height in meters and t in time in seconds. What is the starting height of the riders?
Answers
Answer:
The starting height of the raiders is 39 meters.
Step-by-step explanation:
Physically speaking, a free fall motion is an uniformly accelerated motion due to gravity. Mathematically, speaking the equation of motion for the height of an object under free fall is a second order polynomial (quadratic function).
Let [tex]h(t) = -9.8\cdot t^{2}-5\cdot t + 39[/tex] be the height of the riders, in meters, the starting height is the height evaluated at [tex]t = 0\,s.[/tex] Hence, we proceed to the determined the required data by direct evaluation:
[tex]h(0) = -9.8\cdot (0)^{2}-5\cdot (0) +39[/tex]
[tex]h(0) = 39[/tex]
The starting height of the raiders is 39 meters above the ground.
