Answer:

1) 18 yards

2) x = 24

3) 36 yards

4) y = (-9/98)(x - 24)² + 18

Step-by-step explanation:

The path is symmetrical about x = h

h = (10+38)/2 = 24

x = 24

Distance = 18 + 18 = 36

Vertex: (24,18)

y = a(x - 24)² + 18

At t = 10, y = 0

0 = a(10 - 24)² + 18

a = -18/14²

a = -18/196 = -9/98

y = (-9/98)(x - 24)² + 18

Answer:

x-int:(-2,0)(-4,0) . y-int:(0,8)

Step-by-step explanation:

y = x2+6x+8 and y = (x+2)(x+4)

x-int:

x+2=0

x= -2

(-2,0)

x-int:

x+4=0

x=-4

(-4,0)

y-int: plug 0 for x

y=(0+2)(0+4)

y=8

(0,8)

In order to solve this problem, we will need a little more information, for example, we need to know what the functions are. Let's say the problem looks like this:

Use the drawing tool(s) to form the correct answer on the provided number line. Consider the functions below.

$f(x)=|3x|-3$

and

$g(x)=-x^{2}+8x-5$

Represent the interval where both functions are increasing on the number line provided.

Answer:

See attached picture

Step-by-step explanation:

Since this problem is posted on the algebra section of Brainly, I assume we will need to make use of an algebraic approach to solve this. Basically, the idea is to graph the functions and find the x-values for which both functions increas. In order to graph the functions, we will need to build a table with points for each of the functions. In order to graph the functions you need to pick the x-values you wish and evaluate them in the given functions. (See attached pictures)

Once you got the desired points, you can plot them in the coordinate axis and find the x-values for which both graphs will be increasing. If we take a close look at the graphs we can see the f(x) graph increases in the interval:

(0,∞)

and the g(x) graph increases in the interval:

(-∞,4)

so the interval in which both graphs are increasing will be the region where both intervals cross each other, which will be (0,4)

so that's the interval we draw on our number line. (see attached picture.

Answer and question ok plss

ivolga24 [154]

Answer:

The answer is D(20)

Step-by-step explanation:

I don't know the exact algebraic explanation, however, this is how I did it.

$2^5+2^5=$ $2*2^5$

If you divide the second equation into seperate twos, you will get 2*2*2*2*2*2 = $2^6$

Therefore, $2^x=2^6$ meaning that x is equal to 6. Now The next bit is trial and error, 20-6=14. $3^{y} = 3^{14}$

Last thing to do is to add x+y=6+14. That is why the answer is 20.

If you wait a bit longer, someone will probably have a more algebraic explanation, however, you stated you only needed the answer so I hope this helped.
