Quadrant II

Quadrant III

Quadrant IV

When you subtract the y values you find that each increase in x decreases y by 4.

X is going from 4 to 82 which is 78 units.

78 x 4 = 312

Subtract 312 from the last y value:

209 - 312 = -103

The answer is -103

Answer:

When x = 82, y = -103

Step-by-step explanation:

So an arithmetic sequence is a sequence whose terms differ by a constant value. To find the value of the [tex]n^{th}[/tex] term we need to form an equation for the sequence.

First we need to find the difference between the values of the sequence. In this case the difference is -4:

217 - 221 = -4,  209 - 213 = -4

So the equation is:

[tex]n^{th}[/tex] term = -4n + c

Now we need to find the c, so we substitute the [tex]n^{th}[/tex] term and the term number and solve the equation:

221 = (-4 x 1) + c

221 = -4 + c

c = 225

So the final equation is:

[tex]n^{th}[/tex] term = -4n +225

Now all we need to do is substitute into the equation and find the answer:

[tex]n^{th}[/tex] term = (-4 x 82) + 225

[tex]n^{th}[/tex] term = -328 +225

[tex]n^{th}[/tex] term = -103

Answer:

0 = 0/40

-1 = -40/40

Answer: [tex]62.92 \frac{mi}{h}[/tex]

Step-by-step explanation:

If we are asked about how fast a car is going, this means we are asked about its velocity [tex]v[/tex], which is defined by the relation between the traveled distance [tex]d[/tex] and time [tex]t[/tex]:

[tex]v=\frac{d}{t}[/tex]

Where:

[tex]d=(330+\frac{1}{3}) mi=330.33 mi[/tex] is the traveled distance

[tex]t=(5+\frac{1}{4}) h=5.25 h[/tex] is the time

Solving the equation with the given information:

[tex]v=\frac{330.33 mi}{5.25 h}[/tex]

Finally:

[tex]V=62.92 \frac{mi}{h}[/tex] This is the car's velocity

Answer:

The speed of the car is 77.72 miles per hour

Step-by-step explanation:

To find out how fast is a car travelling when it traveled 330 and 1/3 miles in 4 and 1/4 hours following formula will be used

     Speed=  [tex]\frac{Distance}{Time}[/tex]

Total distance = 330 and 1/3

                        = 330+ 0.33

                        =  330.33 miles

Total time = 4 and 1/4

                 =  4 + 0.25

                 =  4.25 hrs

putting the values in equation we get speed of car

Speed= [tex]\frac{330.33}{4.25}[/tex]

Speed   = 77.72 miles per hour

So the speed of the car is 77.72 miles per hour

The graph that shows the dilation of the rectangle in the attached figure

Step-by-step explanation:

we know that

A dilation is a non rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional

In this problem we have that the scale factor is equal to 2

Remember that

If a scale factor is greater than 1, then the dilation is a enlargement

To find out the dimensions of the dilated figure multiply the original dimensions by the scale factor

The original dimensions of rectangle are

Answer:

1 3/5

Step-by-step explanation:

x - 2y = -4 is the standard form of equation

Solution:

Given equation is:

[tex]y = \frac{1}{2}x + 2[/tex]

We have to write the equation in standard form

The standard form of an equation is Ax + By = C

In this kind of equation, x and y are variables and A, B, and C are integers

From given,

[tex]y = \frac{1}{2}x + 2[/tex]

Simplify the above equation

[tex]y = \frac{x+4}{2}\\\\2y = x + 4[/tex]

Shift the variable terms to the left side of the equation and everything else to the right side

[tex]x - 2y = -4[/tex]

Thus the standard form of equation is found

The ball reaches the ground after 7.76 s

Step-by-step explanation:

The motion of the ball along the vertical direction is a free fall motion, which is affected by the force of gravity only; therefore it is a uniformly accelerated motion (=constant acceleration), so we can use the following suvat equation:

[tex]s=ut-\frac{1}{2}gt^2[/tex]

where

s is the displacement

u is the initial vertical velocity

[tex]g=9.8 m/s^2[/tex] is the acceleration due to gravity

t is the time

In this problem,

u = 38 m/s

Also, we want to find the time t at which the ball hits the ground again: so, when the displacement becomes zero again,

s = 0

Therefore the equation becomes:

[tex]0=38t-\frac{1}{2}9.8t^2\\0=38t-4.9t^2[/tex]

And solving for t,

[tex]t(38-4.9t)=0[/tex]

we have two solutions:

t = 0 (instant at which the ball is kicked)

[tex]38-4.9t=0\\t=\frac{38}{4.9}=7.76 s[/tex]

which is the solution to the problem.

Answer:

5.65685424949 or 5.66

Step-by-step explanation:

In a right-angled triangle, the longest side/leg is called the hypotenuse.

The formula to solve for the hypotenuse is:

hyp^2= side^2+side^2

If the hypotenuse of the triangle is already given then we have to solve for a side.

The formula to solve for the side is:

side^2= hyp^2-side^2

This formula to solve for the side is the opposite of solving for the hypotenuse which is the longest side/leg of the right-angled triangle.

In this question we have to solve for the side.

There are two sides in this triangle. Let's name those sides side a and side b. Side a is already given.

hyp= 9

side a = 7

side^2 = hyp^2-side^2

side b = 9^2 - 7^2

side b = 81 - 49

side b = 32

side b = √32

side b= 5.65685424949. to 2 decimal places -> 5.66

(a) 10^5/10^2 = 1000
(b) x^2/x^6 = 1/(x^4)
(c) x^4y/xy^8 = x^3/y^7

a) To rewrite the expression 10^5/10^2 as the product of two fractions, we can write it as (10^5)/(10^2) = (10 * 10 * 10 * 10 * 10) / (10 * 10).

Next, we can simplify this expression by canceling out the common factors in the numerator and denominator. Since both the numerator and denominator have 10 as a common factor, we can simplify further to get (10 * 10 * 10 * 10 * 10) / (10 * 10) = 10 * 10 * 10 = 1000.

Therefore, the equivalent and simpler expression for 10^5/10^2 is 1000.

(b) For the expression x^2/x^6, we can rewrite it as (x * x) / (x * x * x * x * x * x).

Next, we can simplify this expression by canceling out the common factors in the numerator and denominator. Since both the numerator and denominator have x as a common factor, we can simplify further to get (x * x) / (x * x * x * x * x * x) = 1 / (x * x * x * x).

Therefore, the equivalent and simpler expression for x^2/x^6 is 1/(x^4).

(c) To rewrite the expression x^4y/xy^8 as the product of two fractions, we can write it as (x * x * x * x * y) / (x * y * y * y * y * y * y * y).

Next, we can simplify this expression by canceling out the common factors in the numerator and denominator. Since both the numerator and denominator have x and y as common factors, we can simplify further to get (x * x * x * x * y) / (x * y * y * y * y * y * y * y) = (x^3) / (y^7).

Therefore, the equivalent and simpler expression for x^4y/xy^8 is x^3/y^7.

Answer :after four years the price of car depreciate

Final answer:

It will take approximately 4 years for the car to depreciate to $4520 using the declining-balance method of depreciation with a depreciation rate of 30%.

Explanation:

To calculate the number of years it would take for the car to depreciate to $4520, we can use the declining-balance method of depreciation. The declining-balance method is based on a fixed percentage of the remaining value of the asset. In this case, the rate of depreciation is 30%, so the car's value will decrease by 30% each year.

Let's start by finding the value of the car after one year. We can use the formula:

Value after one year = Initial value - (Rate of depreciation * Initial value)

Plugging in the values, we get:

Value after one year = $18820 - (0.3 * $18820) = $18820 - $5646 = $13174

Now, let's find the value after the second year:

Value after two years = $13174 - (0.3 * $13174) = $13174 - $3952.2 = $9221.8

We continue this process until we reach a value of $4520. By the time the car's value reaches $4520, it will have taken approximately 4 years.

Answer:

  B.  T<-4, -2>, r(90°, O)

Step-by-step explanation:

Point A' is 4 units left and 2 units down from point A, so the translation is T<-4, -2>.

Segment C"D" is on the -x axis, 90° counterclockwise from segment C'D' on the +y axis. Since rotation angles are measured the same way other angles are measured (positive is CCW), the rotation is +90° about the origin.

The congruence transformation that maps the quadrilateral ABCD to A''B''C''D'' is [tex]T_{ < -4, \, -2 > } \circ T_{90^{\circ}}, origin > (ABCD)[/tex] which corresponds with the option B.

B. [tex]T_{ < -4, \, -2 > } \circ T_{90^{\circ}}, origin > (ABCD)[/tex]

A congruent transformation, which is also a rigid transformation is one in which the size and shape of the original figure is preserved.

The coordinates of the vertices of the quadrilaterals ABCD and A'B'C'D' indicates that the transformation from the quadrilateral ABCD to the quadrilateral A'B'C'D' is a translation of 4 units to the left and 2 units downwards, which can be expressed as T<-4, -2>

The side D'C' in the quadrilateral A'B'C'D' is vertical while the side D''C'' in the quadrilateral A''B''C''D'' is horizontal and due to the order of the letters D'' and C'' in D''C'' arranged from left to right suggesting a 90° counterclockwise rotation about the origin, which is a T90°, origin

The congruence transformation that maps ABCD to A''B''C''D'' therefore is the option B, [tex]T_{ < -4, \, -2 > }\circ T_{90^{\circ}}, origin > (ABCDE)[/tex]

Answer:

The length of an edge of the cube = x = [tex]\sqrt[3]{1000}[/tex] = 10 feet

Step-by-step explanation:

i.) A cube has a volume of 1000 cubic feet.

ii) A cube has edges which are all the same length, let us say that the length of an edge of the cube = x feet.

iii) therefore the volume of the cube is = [tex]x^{3}[/tex] = 1000 cubic feet

iv) therefore the length of an edge of the cube = x = [tex]\sqrt[3]{1000}[/tex] = 10 feet

Final answer:

The length of an edge of a cube with a volume of 1000 cubic feet is 10 feet. If each smaller cube has linear dimensions one tenth those of the larger cube, then the volume of each smaller cube is 1 cubic foot.

Explanation:

The volume of a cube is calculated by raising the length of one of its edges to the power of three (cubing it). Since we know the volume of the cube is 1000 cubic feet, we can determine the length of an edge by finding the cube root of the volume. The cube root of 1000 cubic feet is 10 feet, so the length of an edge of the cube is 10 feet.

To find the volume of the smaller cubes mentioned, we note that if their dimensions are one tenth of the larger cube, then each side of a smaller cube will be 10 feet divided by 10, which is 1 foot. The volume of each small cube is then 1 foot cubed, which is 1 cubic foot.

For a visual reference, imagine a larger cube divided evenly into smaller cubes, where the length of each side of the big cube is ten times that of the smaller ones. The result is that each smaller cube's volume is the original volume divided by the cube of 10 (since there are 10 layers of small cubes along each dimension of the big cube).
