Question 4(Multiple Choice Worth 1 points) (08.01 LC) What are the x-intercepts of the parabola? graph of parabola falling from
gulaghasi [49]

Answer:

(4, 0) and (5, 0)

Step-by-step explanation:

Given

See attachment for graph

Required

The x intercepts

This is the point where y = 0

From the graph, we have the following as the x-intercepts:

(x_1,y_1) = (4,0)

(x_2,y_2) = (5,0)

Because the curve crosses the x-axis at the above points

295 feet = _____ meters ?
katen-ka-za [31]

Answer:

Hello! I hope I am correct!

Step-by-step explanation:

295 feet will equal to 89.916 meters.

Steps in order to solve this problem:

First you have to multiply the length in feet by 0.3048.

295x 0.3048 or 295* 0.3048

(295 feet is equivalent to 89.916 meters!)

Will equal 89.916 meters.

Therefore, 295 feet = 89.916 meter

Hope this helps!

Brainliest would be appreciated!

Pls help me i just need help
Ray Of Light [21]

Step-by-step explanation:

the total cost is, of course, first the cost to buy the copier, and then the running costs per copy made.

it is really that easy.

the equations just put this into mathematical form :

A

y = 0.02×x + 800

B

y = 0.06×x + 600

please notice, we put $600 or $800 in as constant term, because these costs are the starting costs that we have, even if we never make a single copy (x = 0).

and then the total cost goes up with every copy we make.

I cannot draw here.

so, to find the number of copies where both copier systems would cost the same, means we have to say both equating deliver the same result :

0.02×x + 800 = 0.06×x + 600

200 = 0.04×x

x = 200 / 0.04 = 5000

when making 5000 copies both costs are the same.

Please help me if u give me an answer could u also give me an explanation on why that’s the answer.
Setler79 [48]
So it’s A

in all the other ones we can see that the angles in the same position as x and 75 are all equal

and because the question tells us that they are all structured the same with p and f being parallel we can assume x is equal to what’s congruent to it

there is a rule that states this

cap congruent angle postulate i believe

which states that if two parallel lines are cut by a transversal, then corresponding angles are congruent
