PLEASE ANSWER I WiLL GIVE BRAINLIEST
Answer 2

Answer:

Exact - 40n m²

Approximate 125.6m²

Step-by-step explanation:

Exact area of the sidewalk - n * (11 m)² - n * (9 m)²

- n * 121 m²- n * 81 m²

Exact area of the sidewalk - 40n m²

To find the approximate area of side walk let us substitute pi equals 3.14.

40*3.14 m²

Approximate area of the side walk - 125.6 m²

Therefore the exact area is 40n m² , the approximate area is 125.6 m²

A football is thrown into the air from an initial height of 4 feet with an upward velocity of 46 ft/sec. The function h = -16t² + 46t + 4 gives the height after t sec.

whats the vertex?

axis of symmetry?

solutions?

2 other points?

and i know the balls max height is 37.06

Answers

Answer:

Vertex = (1.4375, 37.0625)

Axis of symmetry:  t = 1.4375

x-intercept: (2.9595, 0)

y-intercept: (0, 4)

another point: (2, 32)

Step-by-step explanation:

Given function:  [tex]h(t)=-16t^2+46t+4[/tex]

(where h is the height in feet and t is the time in seconds)

The vertex is the turning point of the parabola.

To find the x-value of the turning point, differentiate the function:

[tex]\implies h'(t)=-32t+46[/tex]

Set it to zero:

[tex]\implies h'(t)=0[/tex]

[tex]\implies -32t+46=0[/tex]

Solve for t:

[tex]\implies 32t=46[/tex]

[tex]\implies t=\dfrac{23}{16}[/tex]

Input found value of t into the function to find the y-value of the vertex:

[tex]\implies h(\frac{23}{16})=-16(\frac{23}{16})^2+46(\frac{23}{16})+4=\dfrac{593}{16}[/tex]

Therefore, the vertex is [tex]\left(\dfrac{23}{16},\dfrac{593}{16}\right)[/tex] or (1.4375, 37.0625) in decimal form.

The axis of symmetry is the x-value of the vertex.

[tex]\implies \textsf{Axis\:of\:Symmetry}:t=\dfrac{23}{16}=1.4375[/tex]

To find the x-intercepts, use the quadratic formula.

Quadratic Formula

[tex]x=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}\quad\textsf{when}\:ax^2+bx+c=0[/tex]

[tex]\implies t=\dfrac{-46 \pm \sqrt{46^2-4(-16)(4)} }{2(-16)}[/tex]

[tex]\implies t=\dfrac{-46 \pm \sqrt{2372}}{-32}[/tex]

[tex]\implies t=\dfrac{23 \pm \sqrt{593}}{16}[/tex]

As time is positive,

[tex]\implies t=\dfrac{23 + \sqrt{593}}{16}=2.959474458...\:\sf s\quad only[/tex]

The y-intercept is when t = 0:

[tex]h(0)=-16(0)^2+46(0)+4=4[/tex]

So the curve intercepts the y-axis at (0, 4)

Because of the modelling of the function, there will be a restricted domain:  0 ≤ t ≤ 2.9595

Therefore, to find another point, input a value in the domain into the function and solve:

[tex]t=2 \implies h(2)=-16(2)^2+46(2)+4=32[/tex]

⇒ (2, 32)

If you donate $150 in total a year , How much money did you donate on the first month of the year.

Answers

Answer:

$12.50

Step-by-step explanation:

You donate $150 in total in a year.

To find out how much you donated on the first month, remember the relation between a year and number of months.

⇒ 1 year = 12 months

⇒ 1 month = 1/12 year

Finding the amount donated

Divide the money donated in a year by 12$150/12$12.50

Step-by-step explanation:

5)

y=hypothesis * sin(opposing angle)/sin(angle opposite of hypothesis)

y = 16*sin(30)/sin(90)

y=8

x=hypothesis * sin(opposing angle)/sin(angle opposite of hypothesis)

x=16*sin(60)/sin(90)

x=13.856

6)

sinA/(opposite of angle A) = sinB/(opposite side of angle B) = sinC/(opposite of side of angle C)

sin(90)/u= sin(30)/2

u *sin(30) = 2* sin(90)

u *sin(30) = 2

u=2/sin(30)

u=2/0.5

u=4

sin(60)/v= sin(30)/2

v *sin(30) = 2* sin(60)

If an orthocenter lies inside of a triangle, then the triangle must be acute.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

Orthocenter of a triangle is the intersection of any two of three altitudes of a triangle.

The third altitude usually pass through the point of the first two altitudes.

When the orthocenter lies inside a triangle, the angles formed by the intersection of the three altitudes is less than 90 degrees.

An acute triangle is a type of triangle whose angles are less than 90 degrees.

Hence, If an orthocenter lies inside of a triangle, then the triangle must be acute.

[tex]\frac{x^{2}+mx+n }{9-x^{2} } /\frac{x^{2} +6x-16}{x^{2} +px+q} = \frac{-x+3}{x+8}[/tex]

Change the division of the two fractions in to multiplication

[tex]\frac{x^{2}+mx+n }{9-x^{2} } * \frac{x^{2} +px+q}{x^{2} +6x-16} = \frac{-x+3}{x+8}[/tex]

Factor what we can

[tex]\frac{x^{2}+mx+n }{(3-x)(3+x)} * \frac{x^{2} +px+q}{(x-2)(x+8)} = \frac{(3-x)}{x+8}[/tex]

Cross multiply and simplify (x+8)/(x+8)

(x² +mx +n) (x² +px +q) = (x -3) (x -3) (x +3)( x -2)

We can conclude from the slope intercept result, the equation with no x-intercept is  C) y=0x + 3,    D) y=0,    E) y=5

What is slope intercept?

In mathematics, the slope-intercept form of a linear equation is an equation of the form y = mx + b, where m is the slope of the line and b is the y-intercept, which is the point on the line where it intersects the y-axis.

Because it allows you to easily view the line and identify its slope and y-intercept, the slope-intercept form is a useful way to describe a line's equation. The slope of the line denotes its steepness, while the y-intercept indicates where the line intersects the y-axis.

The x-intercept of an equation is the point at which the equation's graph intersects the x-axis. When the value of y is zero, something happens. As a result, an equation lacks an x-intercept horizontal line that does not intersect the x-axis.

C) y=0x + 3 (A horizontal line with a y-intercept of 3 that does not cross the x-axis.)

D) y=0 (This is a horizontal line that passes through the origin but does not intersect the x-axis.)

E) y=5 (This is a horizontal line that passes through (0,5) but does not cross the x-axis.)

F) y=3x+0 (This is a straight line travelling through the origin and does cross the x-axis) (This is a straight line passing through the origin and does cross the x-axis)

A copy machine makes 44 copies per minute. How many copies does it make in 4 minutes and 15 seconds?

Answers

Answer: 102 copies

Step-by-step explanation:

4 minutes and 15 seconds are 4.25 minutes, so it will make 102 copies in that time

44 copies/minute
If there are 44 copies made in 4 minutes; 44 (copies) x 4 (minutes) = 176 copies

To find how many copies are in a fraction of a minute

Divide 44 by whatever value your time frame is by 60; 44 / (60/15) = 11 copies

176 copies + 11 copies = 187 copies in 4 minutes and 15 seconds
