16. Physical Science A ball is dropped from a
height of 500 meters. The table shows the height
of each bounce, and the heights form a geometric
sequence. How high does the ball bounce on the
8th bounce? Round your answer to the nearest
tenth of a meter.

Answer:

14

Step-by-step explanation:

Answer:

the answer is X = 14

Step-by-step explanation:

So you need to single out the X

You do this by doing the opposite of X,

right now X is being multiplied by 14

The opposite of Multiplaction is division

That means you divide X by 14

But dont forget, what you do one side you do to the other.

This means you also Divide 196 by 14

196 ÷ 14 = 14

meaning X = 14

Answer:

y=2/3x-1

Step-by-step explanation:

slope intercept form is y=mx+b

where m is the slope and b is the y-intercept

You already know that the slope is 2/3 and the intercept is -1 so all you have to do is plug it in

y=2/3x-1

Answer:

  y = 3x + 4

Step-by-step explanation:

The given line is in the form ...

  y = mx + b

where m is the slope (3) and b is the y-intercept (-1).

The parallel line will have the same slope. The given point (0, 4) is the y-intercept, so the desired equation is ...

  y = 3x +4

2x³ + xy and 2 + 5x - 3x³ are trinomials with degree 3.

Options C and D are the correct answer.

Polynomial is an equation written with terms of the form kx^n.

where k and n are positive integers.

There are quadratic polynomials and cubic polynomials.

Example:

2x³ + 4x² + 4x + 9 is a cubic polynomial.

4x² + 7x + 8 is a quadratic polynomial.

We have,

The degree of a polynomial is the highest power of the variable in the polynomial.

a.

2xy² is a monomial with degree 3 (degree of x is 1 and degree of y is 2).

b.

3x + 3x² is a binomial with degree 2 (degree of x is 2).

c.

2x³ + xy is a trinomial with degree 3 (degree of x is 3).

d.

2 + 5x - 3x³ is a trinomial with degree 3 (degree of x is 3).

Therefore,

2x³ + xy and 2 + 5x - 3x³ are trinomials with degree 3.

Scale factor is  [tex]\frac{14}{21}[/tex].

A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object. If the scale factor is a whole number, the copy will be larger. If the scale factor is a fraction, the copy will be smaller.

Given

The rectangle on the right is a scaled copy of the rectangle on the left.

[tex]\frac{42}{63}[/tex] and 15 ÷ [tex]\frac{45}{2}[/tex]

[tex]\frac{42}{63}[/tex]

Rationalizing [tex]\frac{42}{63}[/tex] by 45

= [tex]\frac{42(45)}{63(45)}[/tex]

= [tex]\frac{1890}{2835}[/tex]

15 ÷ [tex]\frac{45}{2}[/tex]

Rationalizing 15 ÷ [tex]\frac{45}{2}[/tex] by 63

= [tex]\frac{30(63)}{45(63)}[/tex]

=  [tex]\frac{1890}{2835}[/tex]

If we want to find the scale factor we have to equal the proportions of two rectangles.

∴ Scale factor =  [tex]\frac{1890}{2835}[/tex] = [tex]\frac{14}{21}[/tex]

Hence, scale factor is  [tex]\frac{14}{21}[/tex].

Answer:

The number expected to be cheese are 42 Pizzas

Step-by-step explanation:

According to the information provided, the total choices of Pizza at a local pizza shop are as follows:

Pizza                Choice

Peperoni             11

Supreme              7

Cheese                6

Hawaiano            3

Total                    27

The total pizza sold were 189, out of which the number expected to be cheese will be calculated by dividing the total number of choices and multiplying it with the required type of pizza chosen. This is done as follows:

189 / 27 * 6 = 42 Cheese Pizza

Answer:

18.18%

Step-by-step explanation:

The percentage of sweets in the bag that are yellow is as follows:

Let us assume the number of yellow sweets be x

So for number of blue sweets be 4x

And, the number of red sweets be 0.5x

So it could be written as

Blue Red Yellow

4        0.5    1

8        1        2

So for yellow, the percentage is

= 2 ÷ (8 + 1 + 2)

= 2 ÷ 11

= 18.18%

Answer:

v= -3 and v= 11

Step-by-step explanation:

v^2 - 8v -33 = 0

v^2-11v+3v-33=0

v(v-11) +3(v-11)=0

(v+3)(v-11)=0

v+3=0          and          v-11=0

Step-by-step explanation:

Answer:

The time it will take is 8hours 45mins.

Step-by-step explanation:

Since y = –240x represents a submarine descent. We are looking for how long, that is the time, it will take for the submarine to make a descent of 2100. We know that y is the elevation, if it is descending it will be in the negative direction, making it -ve.

A descent of 2100 means y = –2100. Hence,

–2100 = –240x

x = –2100/–240 = 8.75hours = 8hours 45minutes. (0.75hours = 3/4hours = 3/4 x 60mins = 45mins).

Answer:

c. 80

Step-by-step explanation:

cos x = sin(x-70)

cos x = cos [90-(x-70)]

cos x = cos (90-x +70)

cos x = cos 160 -x

x= 160-x

2x = 160

x =80

Answer:

Using the identities

tanx = [tex]\frac{sinx}{cosx}[/tex] , cotx = [tex]\frac{cosx}{sinx}[/tex]

Consider the left side

= [tex]\frac{\frac{sinx}{cosx} }{\frac{sinx}{cosx}+\frac{cosx}{sinx} }[/tex]

= [tex]\frac{\frac{sinx}{cosx} }{\frac{sin^2x+cos^2x}{cosxsinx} }[/tex]

= [tex]\frac{\frac{sinx}{cosx} }{\frac{1}{cosxsinx} }[/tex]
