Answer:
a concave lens is exactly the opppostie with outer surfaces curving inward, so it makes parallel light rays curve outward or diverge. That's why concave lenses are sometimes called diverging lenses. ... The distance from the center of the lens to the focal point is, again, the focal length of the lens.

During the Martinez family trip, they drove from home to a ski lodge, a distance of 52 4 5 miles, and then drove an additional 14 4 5 miles to visit friends.
Answers
Answer:
[tex]134 \frac{6}{5}[/tex]
Step-by-step explanation:
The computation of the distance travelled is shown below:
Total distance would be
[tex]= 52 \frac{4}{ 5} + 14 \frac{ 4}{5}\\\\= \frac{264}{5} + \frac{74}{5}\\\\= \frac{338}{5}[/tex]
Now if the same route would taken again in order to back home
So, the total distance would be doubled
[tex]= \frac{338}{5} \times 2\\\\ = \frac{676}{5} \\\\= 134 \frac{6}{5}[/tex]

A rectangle has a perimeter of 238 meters and a length of 67 meters what is the area of the rectangle
Answers
Answer:
3,484 meters squared
Step-by-step explanation:
Since it’s a rectangle, opposite sides are the same length. This means 2 of the sides are 67 meters each, since the length of the rectangle is 67 meters. To find the width, add the 2 sides together that we know the length of (in this case it would be 67+67) and subtract it from the total perimeter (238-[67+67]). Take the result (104) and divide it by 2 (104÷2=52). Now that we know the width is 52 meters, you can find the area by multiplying the length times the width (67*52=3,484 meters)
Remember that the perimeter is the total length around the outside of the shape, and the area is the space inside of the shape

Answer:
[tex]y = \frac{-3}{4}[/tex]
Step-by-step explanation:
[tex]\frac{y}{2} + \frac{1}{4} = \frac{y}{6}[/tex]
Lets take all the variable terms in L.H.S & all the constant terms in R.H.S.
(While taking a term from one side to another side , it's sign changes )
⇒ [tex]\frac{y}{2} - \frac{y}{6} = -\frac{1}{4}[/tex]
Now in L.H.S. , lets solve the fractions and reduce its numerator and denominator .
⇒ [tex]\frac{3y - y}{6} = -\frac{1}{4}[/tex]
⇒ [tex]\frac{2y}{6} = -\frac{1}{4}[/tex]
⇒ [tex]\frac{y}{3} = -\frac{1}{4}[/tex]
Lets multiplying 3 on both the sides .
⇒ [tex]\frac{y}{3} \times 3 = -\frac{1}{4} \times 3[/tex]
⇒ [tex]y = \frac{-3}{4}[/tex]

Help pls I need it now
Answers
Answer and Step-by-step explanation:
So, the format you should choose is the second one.
This is what goes in each box:
[4] (p - [6]) = [12]
The 4 is multiplying the price for 1 of the items (and it is 4 because there are 4 items), the 6 is taking away 6 dollars (because coupons take away money from amount) and 12 is the total amount of money.
Now, we solve for p.
Divide each side by 4.
p - 6 = 3
Now, add 6 to each side.
p = 9.
Each item cost 9 dollars.

The cone and cylinder below have equal surface area
Answers
Answer:
Option B, False
Step-by-step explanation:
Step 1: Get the surface area formulas for both shapes
Surface Area Formula for Cone: [tex]A = \pi * r(r + \sqrt{h^{2} + r^{2}})[/tex]
Surface Area Formula for Cylinder: [tex]A = 2\pi rh+2\pi r^{2}[/tex]
Step 2: Plug in the values and solve
Cone: [tex]A = \pi * r(r + \sqrt{(3r)^{2} + r^{2}})[/tex]
Cone: [tex]A = \pi r^{2} + \pi \sqrt{10}r^{2}[/tex]
Cylinder: [tex]A = 2\pi r*r+2\pi r^{2}[/tex]
Cylinder: [tex]A=4 \pi r^{2}[/tex]
Step 3: Compare
[tex]\pi r^{2} + \pi \sqrt{10}r^{2}\neq 4 \pi r^{2}[/tex]
They are not equal, therefore the answer is False.

Two functions are shown below
f(x)=8x+10
g(x)=6x-4
What is f(4)-g(3)?
Answers
Answer:
c.28
Step-by-step explanation:
Given
f(x) = 8x + 10 and g(x) = 6x - 4
f(4) = 8*4 + 10
= 32 + 10
= 42
g(3) = 6 * 3 - 4
= 18 - 4
= 14
Now
f(4) - g(3)
= 42 - 14
=28
hope it will help :)
f(4)= 8(4)+10= 42
g(3)= 6(3)-4= 14
f(4)- g(3)= 42-14= 28

Since $110 is the constant and 6 is the coefficient because it is changing with each time he rents a tennis ball. The equation is 110+6t=386 where t in this case can represent (return groundstrokes)
110+6t=386 solve for t
6t=276
t=46
So he can return ground strokes 46 times
