The time for the projectile to hit the ground from the given position is 1.5 s, which is obtained using the concept of time period and velocity of a projectile.

What is a projectile?

A projectile is defined as an object that has the force of gravity as the only force occurring on it. Acceleration in the projectile motion always acts vertically.

Calculation of the time taken by projectile to hit the ground

The given parameters:

The starting velocity of the projectile, u = 48 ft / s

Height of the projectile, h = 190 ft

Model of the projectile path, h(t) = - 16(t)2 + 48t + 190          —-- 1

When the projectile hits the ground, the final velocity, v = 0

differentiating equation 1 w.r.t t, we get,

(dh(t)) / (dt) = - 32t + 48

Putting dh(t) / dt = 0, we have,

- 32t + 48 = 0

32t = 48

t = 48 / 32

t = 1.5 s

Hence, the time taken by the projectile to hit the ground is 1.5 s.

The coordinates of the point B are (-5, 6)

The given parameters are

A = (-8, 6)

Point = (2, 6)

Proportion = 2/3

Because the y coordinates are the same, we can make use of only the x coordinate

So, we have

Point = Proportion * (B - A)

This gives

2 = 2/3 * (B + 8)

Multiply through by 3/2

So, we have

3 = B + 8

Subtract 8 from both sides

B = -5

Hence, the coordinates of the point B are (-5, 6)

A scaled copy of polygon with the scaled factor of 2 is Scale factor is defined as

It is a growing organism that falls between (0, infinity). According to the scale factor, an original figure might be either raised or decreased.

Consider two circles that appear to be the same. The word "identical" does not guarantee that both circles are of similar size. They could have various radii. One figure would be the other figure scaled down.

The ideas of ratio and proportion are intimately related to scale considerations. A given amount is multiplied or divided in ratio and proportions to create a new quantity.

A Scaled copy involves multiplying the lengths in the original figure by scale factor.

Here scale factor = 2,

Since the scale factor > 1, so there is an enlargement.

So, the scale copy's sides are 2 times of the sides of figure A.

They will save $100 if they purchase together rather than separately.

If this week, the store is offering one free window for each purchase of 4, then the price of 5 windows will be just equal to the price of 4.

1 window = $100

5 windows = 4 x $100 = $400

If

Dave needs 7 windows  

Doug needs 8 windows

total they need together = 7+8 = 15 windows.

Buying at the offer of $400/5 windows,

they should buy 3 sets of 5 windows.

3 x 5 = 15

cost when bought together : 3 x $400

cost when bought together : $1200

If they bought separately,

Dave : 7 = 5 + 2

cost = $400 + 2($100)

cost = $600

Doug : 8 = 5 + 3

cost = $400 + 3($100)

The value of the height of the right prism is given by the formula, h = (SA - 2B) / P. It is gained by using the surface area of the right prism.

What is the right prism?

A right prism is a three-dimensional closed figure with 6 faces, 8 corners and 12 edges. It is called a right prism because, in this prism, the angle between the base and the sides is 90 degrees. All the faces of a right prism are rectangular, hence sometimes also called a right rectangular prism.

Calculation of h for the right prism

We know the  surface area of the right prism is given by:

SA = Ph + 2B

Ph + 2B = SA

Subtracting 2B from both sides of the above equation, we have,

Ph + 2B - 2B = SA - 2B

Ph = SA - 2B

Dividing both sides of an equation by P, we get,

(Ph) / P = (SA - 2B) / P

h = (SA - 2B) / P

Hence, the value of h can be found using the formula, h = (SA - 2B) / P

1. A line segment can be written with just naming it by its end points and a bar above it while the name of a line requires an double-headed arrow mark above its name.

2. For constructing both a perpendicular and an angle bisector, we need to construct two arcs using a compass and their intersection point. A perpendicular bisector divided a line segment into two equal parts whereas an angle bisector divides an angle into two equal parts.

3. A perpendicular bisector can be drawn by drawing two arcs each above and below the line segment and joining using an straight edge.

1. A line and a line segment may sound quite similar however they are very different. A line, in short, is a line that never ends so it's infinite. It's the same for a line segment except at its end it is indicated by dots rather than arrows.

This difference can be seen in naming them too. A line segment is named using the initial and terminal points of the segment. Sometimes we put a 'bar' mark above its name. For example, [tex]\bar{AB}[/tex]

For a line of infinite length, it is named simply as 'line A' or 'line B' or sometimes put a double-headed arrow mark above its name.

2. A perpendicular bisector and an angle bisector are similar because they both require the need to find where two arcs meet. They are different because angle bisectors split into congruent angles meanwhile a perpendicular bisector splits into congruent segments.

Constructing a perpendicular bisector is similar in the sense that both are drawn using straight edge and compass and need to find the intersection point of the arcs. But they are different in their use as perpendicular bisector equally divides a line segment and an angle bisector equally divides an angle.

3. We have an unmarked straightedge and a compass. First put the compass at one end point A of the line. Then stretch the compass to a length more than half of the line segment AB to be bisected. In the next step, draw an arc above and one below the line. Next put the compass on the other end B of the line. Then repeat drawing two arcs, each above and below the line and also intersecting with the previous arcs. Finally join the two points got with a line cutting the line segment AB. This will be the perpendicular bisector of the line AB.

The value of 'x' in the given question is 27°.

Obtuse Angle may be defined as an angle that is greater than 90° and less than 180°. It may be also defined as an angle between a right angle and a straight-line angle.

From the question we can conclude that the given angles are vertically opposite to each other, and vertically opposite angles are always equal to each other.

Vertically opposite angles are formed when two lines are intersecting each other and the angles formed on each side of the intersection point are called vertically opposite angles.

Now according to the question:

[5(x-4)]°=(4x+7)°

Rearranging the terms:

(5x-20)°=(4x+7)°

=>x=27°

Answer:

0.35

Step-by-step explanation:

3/6=1/2

7/10=0.7

1/2=0.5,0.5×0.7

=0.35

Answer: 7/20

Step-by-step explanation:

3/6*7/10= 0.35

First write down the decimal number divided by 1 like this:

0.35

1

As we have 2 digits after the decimal point in the numerator, we need to multiply both the numerator and denominator by 102 = 100, so that there is no decimal point in the numerator

0.35 × 100

1 × 100

=

100

Since the greatest common factor of 35 and 100 is 5, we can simplify the fraction and show the same amount

35 ÷ 5

The sales on which Joyce earns commission is the sale beyond $20,000 which is $2,650. So the total pay for a month for Joyce in which her sales is $22,650 is $1748.75.

Joyce is paid $1,550 per month plus a commission of 7.5% on all sales of more than a $20,000 monthly quota. For the given month her sales is $22,650.

Percentage means a number or a ratio represented in the form of fractions of 100. It is represented using the percentage sign ‘%’. The abbreviations used to represent the percentage are ‘pct’ or ‘pc’. In other words, the percentage is defined as how much of one quantity is made by another quantity and it is evaluated in terms of 100.

Total pay of Joyce = Her pay per month + Commission that she gets

Commission she gets is on the sales beyond $20,000.

Here, commission is on $22,650 - $20,000 = $2,650

She gets 7.5% commission. So, her commission is 7.5% * $2,650

=> 75/1000 * $2,650 = $198.75

So, the total pay of Joyce is $1,550 + $198.75

=> $1748.75 for the month.

The triangle with vertices located at X(-11 , 0), Y(-11 , -8), and Z(-1 , -4) has its centroid located at (-23/3 , -4).

The centroid of a triangle is the point inside the triangle where the three medians intersect. The median of a triangle is the line the connects the midpoint of a side and the opposite vertex.

To get the centroid of a triangle, use the formula given by:

C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]

where C is the centroid of the triangle located at (x , y)

x1, x2, and x3 are the x-coordinate of the vertices of the triangle

y1, y2, and y3 are the y-coordinate of the vertices of the triangle

Let Point 1(x1 , y1) = X(-11 , 0)

Point 2(x2 , y2) = Y(-11 , -8)

Point 3(x3 , y3) = Z(-1 , -4)

Plug in the values in the formula.

C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]
