Answer:

A.

Step-by-step explanation:

Your answer is A. because it crossed the x axis at (0,0) and it has a y-intercept of (1,-3)

Answer:

A shows the equation y = -3x

Answer:

40 feet (after 1.5 seconds).

Step-by-step explanation:

The height h of the ball after t seconds is modeled by the function:

[tex]h(t)=-16t^2+48t+4[/tex]

And we want to determine the ball's maximum height.

Since the given function is a quadratic, the maximum height occurs at the vertex point.

For quadratics, the vertex point is given by the formulas:

[tex]\displaystyle \Big(-\frac{b}{2a},f\Big(-\frac{b}{2a}\Big)\Big)[/tex]

In this case, a = -16, b = 48, and c = 4.

Therefore, the t-coordinate at which the vertex occurs is:

[tex]\displaystyle t=-\frac{48}{2(-16)}=\frac{48}{32}=\frac{3}{2}[/tex]

So, the maximum height occurs after 1.5 seconds.

Then the maximum height will be:

[tex]\begin{aligned}\displaystyle h\Big(\frac{3}{2}\Big)&=-16\Big(\frac{3}{2}\Big)^2+48\Big(\frac{3}{2}\Big)+4\\\\ &=-16\Big(\frac{9}{4}\Big)+24(3)+4\\\\&=-4(9)+72+4\\\\&=40\text{ feet}\end{aligned}[/tex]

So, the maximum of the ball is 40 feet (after 1.5 seconds).

Depending on skill level either of them could win, for example if the 10 players are able to overwhelm the 8 players they will win, but if the 8 players have better players they could win, depending on their skill, even though the 10 player team has a better chance to win, the 8 player team could win.

Answer: 12

Step-by-step explanation:

Answer:

103

Step-by-step explanation:

it has to add up to 180 so

180-77=103

Answer:

124

Step-by-step explanation:

The measure of arc mFD in the above figure is 130°.

The arc of a circle is a portion of the circumference of that circle. It's outlined as a continuous curve that connects two points on the circle. The two endpoints of the arc are known as the arc's endpoints, while the center of the circle is appertained to as the arc's center.

The extent of an arc is directly proportional to the size of the angle it subtends at the center of the circle. However, the arc will be longer, and if the angle is inferior, If the angle subtended is substantial.

From the figure, it is evident that ∠AOC = 90° and ∠AOB = 140°.

As it is known that the whole angle is 360°.

So,

∠AOB + ∠AOC + ∠BOC = 360°

140° + 90° + ∠BOC = 360°

∠BOC = 360° - 140° - 90°

∠BOC = 360° - 230°

∠BOC = 130°

So,

mBC = 130°

Also, as evident from the figure,

mFD = mBC

So,

mFD = 130°.

Therefore, the measure of arc mFD is 130°.

Answer: y = 8/3x + 4

Answer:

49.47 m

Step-by-step explanation:

You will need to use the cosine function

which is the ratio adjacent side/hypotenuse

So, let x = length of guy wire

then   cos 14 = 48/x

         x cos 14 = 48

             x = 48/cos 14

                = 49.47 m

Note:  You must memorize the definitions of all the trig functions so you can do problems like this one.  OK?

Answer:

X= 6.4   ∠A=68.8

Step-by-step explanation:

We know that these 2 angle must equal 180 so we use the equation:

180=7x+24+3x+92

OR

180=7x+3x+24+92

Then, we add like terms (both variable and numbers)

180=10x+116

After that, we solve

180=10x+116

-116        -116

__________

64=10x

________

64/10 = x

________

6.4=x

Now that we have found x, we can plug in x to figure out the new equation to find the angle of A (or B).

∠A= 7(6.4)+24

If we solve that, it would be:

∠A=44.8+24

___________

∠A=68.8

D = 100

Step-by-step explanation:

[tex]\left[\begin{array}{cccc}3&2&1&-8\\-1&-2&4&7\\1&-6&-3&15\end{array}\right][/tex]

         3    2    1

D =   -1    -2    4    =   3(-2)(-3) + 2(4)(1) + 1(-1)(-6)  

         1    -6   -3

                                    - 1(-2)(1) - 3(4)(-6) - 2(-1)(-3)

                           =  18 + 8 + 6 + 2 + 72 - 6

                           =  100
