A golf ball is hit in not the air represented by the equation y= -3x^2+18x+45. The maximum height the ball will reach is____ feet

Answers

Answer 1

Answer:

72 ft

Step-by-step explanation:

Here, we want to get the maximum height the ball will reach

the maximum height the ball will reach is equal to the y-coordinate of the vertex of the equation

So we need firstly, the vertex of the given quadratic equation

The vertex can be obtained by the use of plot of the graph

By doing this, we have it that the vertex is at the point (3,72)

Thus, we can conclude that the maximum height the ball can reach is 72 ft

if ax+bx=a^2-b^2 then what is the value of x​

Answers

Answer:

Factorise both sides of

ax+bx=a2−b2  

and get

(a+b)x=(a+b)(a−b).  

If  

a+b≠0,  

because division by 0 is not allowed, then divide by a + b and get

(a+b)xa+b=(a+b)(a−b)a+b.  

It reduces to

x=a−b.  

If a+b=0, then  

ax+bx=a2−b2 is  

(a+b)x=(a+b)(a−b)  

and this simplifies to

0x=0(a−b),  

that is,

0=0,  

so that the value of x is indeterminate.

A door is fixed at the point O. Ben opened it by an angle of 30°. The area swept by the door was {25}{12}\pi\

Answers

Answer:

5 units

Step-by-step explanation:

Area swept by the floor will be the area ofd a sector

Area of a sector = theta/2π * πr²

We are to find the radius r

Given

Area=  25π/12

theta = 30° = π/6

Substitute

25π/12 = 30/360 * πr²

25π/12 = 1/12 * πr²

25/12 = r²/12

r² = 25

r = √25

r = 5

Hence the radius od the part swept by the door is 5 units

what are sides 'a' and 'b' called in a right triangle

Answers

Answer:

The relation between the sides and angles of a right triangle is the basis for trigonometry.

Step-by-step explanation:

The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (sides a and b ).

Answer:

The legs

Step-by-step explanation:

In a right triangle, sides a and b are called "the legs." These are the sides that create the right angle. Side c is called the hypotenuse and it is the longest side of a right triangle. Side c is opposite of the right angle.

If the simple interest on ​$1,000 for 8 years is ​$​ 480 then what is the interest​ rate?

Answers

Answer:

6%

Step-by-step explanation:

Given data

Principal = ​$1,000

Time= 8 years

Simple interest= ​​$480

The expression for the simple interest is

Simple interest= PRT/100

Substitute

480= 1000*R*8/100

Cross multiply

480= 8000R/100

480*100= 8000R

48000= 8000R

Divide both sides by 8000

R= 48000/8000

R=6%

Answer:

y > 4x - 2

Step-by-step explanation:

The basic format of a line in slope-intercept form is,

[tex]y=mx+b[/tex]

This format undergoes no change when one implements it for the use of a two-variable inequality.

The parameter (m) represents the slope of a line, this can be found by using the formula ([tex]\frac{rise}{run}[/tex]). Traditionally, one would use a formula to find the slope of a line that is the following, ([tex]\frac{y_2-y_1}{x_2-x_1}[/tex]). However, in the given situation, one can simply count the number of boxes from one point with respect to the x-axis to another, and thus get (4).

The parameter (b) represents the point in which the graph intersects the y-axis, one can see that this point is (-2).

Since the line is dotted, one would only use the greater than symbol, not the greater than or equal-too-symbol.

Finally, since the area above the line is shaded, therefore one knows that it is (y) is greater than.
