Answer:

270

Step-by-step explanation:

One turn would put you in quadrant 2 and would be 90.  A second turn would put you in quadrant 3 and that would be 180.  A third turn would put you in quadrant 4 and that would be 270.  I know that it is hard to see what I mean by a turn.  It would be if you had a piece of tracing paper with the figure drawn on it and you turn the paper at the origin so that the lines at the corners would like up, each turn would be 90 more degrees.

Answer: 1.90 miles

Step-by-step explanation:

The conversion rate for meters to kilometers is 1 meter for 0.001 kilometers. Using this rate you can do, [tex]3070m*\frac{0.001km}{1m}[/tex]. The m units cancel and you're left with 3.07km. Since we are given the conversion rate of 1 kilometer = 0.62 miles, we can do, [tex]3.07km*\frac{0.62mi}{1km}[/tex]. again the km units cancel and you're left with 1.9034 mi. Rounded to the nearest hundredth to get 1.90.

Answer:

Step-by-step explanation:

Simplify ((b^4)^4) / ((b^2)^3).First lets simplify the numerator. ((b^4)^4). The notation is b to the fourth power, to the fourth power, which is multiplying sixteen b’s. That explains why we multiple the exponents, to get b^(16) for the numerator.Similarly we simplify the denominator by multiplying the exponents for ((b^2)^3) = b^6.Putting the simplified numerator and denominator together is (b^(16))/(b^6).The six b’s in the denominator cancel six b’s in the numerator for (b^(16))/(b^6) = b^(10). Final answer b^(10).Note, another way to view (b^(16))/(b^6) = (b^(16)) * (b^(-6)) then add the exponents to have the same answer (b^(10))

a)Amount of money left on Pablo's card in dollars = $100 - $15x

= $(90 - 15x)

b) Amount of money left on Teresa's card in dollars= $70 - $10x

= $(70 - 10x)

c) Write an equation to show that the two cards have the same amount of money left on them [don't know how to do this part.

$100 - 15x = $70 - 10x

Let x be the number of pizzas purchased. For each card, write an expression for the amount of money left on the card after purchasing x pizzas.

For Pablo

Keith received a gift card of $100 for a pizza restaurant. The restaurant charges $15 per pizza.

x numbers of pizza costs = $15x

Hence, the amount of money left on Pablo's card after purchasing x pizzas = $100 - $15x

For Teresa,

Mary received a gift card of $70 for a different pizza restaurant. The restaurant charges $10 per pizza.

Hence, x number of pizzas cost =$10 × x

= $10x

Therefore, the amount of money left on Mary's card after she buys x pizzas =

$70 - $10x

Amount of money left on Pablo's card in dollars = __________

Amount of money left on Teresa's card in dollars=____________

Write an equation to show that the two cards have the same amount of money left on them.

To find the equation that shows that the two cards have the same amount of money =

Equation 1 = Equation 2

$100 - 15x = $70 - 10x

Collect like terms

-15x + 10x = $70 - $100

-5x = -30

x = 30/5

x = 6

Hence, anytime Pablo and Teresa buys ,6 pizzas their gift card will have the same amount of money left on them.

The peak height reached at 144 feet, and the graph passing through points (0, 120), (1, 144), (2, 120), gives;

1. The vertex form of a quadratic equation is f(x) = a•(x - h)² + k

Where;

a = The leading coefficient

(h, k) = The coordinates of the vertex.

Let t represent the time of travel of the ball and let h represent the height.

From the given table, we have;

f(t) = a•(t - h)² + k

f(0) = 120 = a•(0 - h)² + k = a•h² + k

120 = a•h² + k

f(1) = 144 = a•(1 - h)² + k = a•(h² - 2•h + 1) + k

f(1) = a•(h² - 2•h + 1) + k

f(1) - f(0) = 144 - 120 = 24 = -((2•h - 1)•a

24 = -((2•h - 1)•a

f(2) = 120 = a•(2 - h)² + k

f(2) - f(1) = -24 = -((2•h - 3)•a

(f(1) - f(0)) - (f(2) - f(1)) = 48 = -2•a

Therefore;

a = -24

24 = -((2•h - 1)•a

24 = -((2•h - 1)×(-24)

-1 = -((2•h - 1)

2•h - 1 = 1

h = 2/2 = 1

h = 1

120 = a•(2 - h)² + k

120 = (-24)•(2 - 1)² + k

k = 120 + 24 = 144

Which gives;

The vertex form is y = -24•(x-1)² + 144

From the vertex form, we have;

y = -24•(x-1)² + 144 = -24•(x²-2•t+1) + 144

y = -24•(x²-2•tlx+1)+ 144 = -24•x²+48•x - 24 + 144

y = -24•x²+48•x + 120

y = -24•x² + 48•x - 24 + 144 = -24•x²+ 48•x + 120

y = -24•x² + 48•x + 120

The height of the ball after 1.5 seconds is

y = -24×1.5² + 48×1.5 + 120 = 138

we now have 3/2 and five inches

3 is 1.5*2

5*1.5 is 7.5

Answer:

7.5in

Step-by-step explanation:

If the original room's dimensions are (15ft x 10ft). Then the new scaled-down version is (?ft x 5in) we can set up a ratio of 10/5 = 2 to find that the scale from the room to the drawing is being shrunk by a factor of 2. So if you take 15/2 you will get your final answer of the new length of 7.5in!

The direction of the vector v in standard position is approximately 253.301°.

Vectors in rectangular form present the change of each of the two variables parallel to orthogonal axes. Each point is described by the following definition:

v = (Δx, Δy)                         (1)

And the direction of a vector is equal to this inverse trigonometric function:

θ = tan⁻¹ (Δy / Δx)              (2)

If we know that Δx = - 3 and Δy = - 10, then the direction of the vector is:

θ = tan⁻¹ (- 10 / - 3)

θ = tan⁻¹ (10 / 3)

θ ≈ 253.301°

The direction of the vector v in standard position is approximately 253.301°.

The solution to the linear equation are x = 2 - y/13 and y = 26 - 13x.

It is required to find the solution to the linear equation.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign. Equation, statement of equality between two expressions consisting of variables and/or numbers.

Given:

The equation is

13x + y = 26

We have to find the value of x and y .

According to given question we have

13x + y = 26

Subtract 13x from both sides we get,

y = 26 - 13x

Subtract y from both sides

13x = 26 - y

Divide through by 13

x = 2 - y/13

Therefore, the solution to the linear equation are x = 2 - y/13 and y = 26 - 13x.

When p ≠ q, the equation has no solution

The given equation is presented as follows;

[tex] \frac{2 \cdot x + p}{q} = \frac{2 \cdot x + q}{p} [/tex]

If p = q, we have;

[tex] \frac{2 \cdot x + q}{q} = \frac{2 \cdot x + q}{q} [/tex]

[tex] \frac{2 \cdot x + p}{p} = \frac{2 \cdot x + p}{p} [/tex]

Therefore, the equation has an infinite number of solutions when p = Q

If p ≠ q, and x = 3, we have;

[tex] \frac{2 \cdot x + p}{q} = \frac{2 \times 3 + p}{q} = \frac{6 + p}{q} [/tex]

[tex] \frac{2 \cdot x + q}{p} = \frac{6 + q}{p} [/tex]

Answer:

  (A)  (x -2)

Step-by-step explanation:

You want to know a factor of the function whose values given in the table include (x, y) = (2, 0).

A polynomial function y = p(x) will have a factor of (x-a) if and only if p(a) = 0.

The table shows y=0 for x=2, so this polynomial function will have a factor of (x -2).

__

Additional comment

The function shown in the table is ...

  y = (x -2)²

so it actually has two factors that are (x -2).

You can tell this is a polynomial function of degree 2 because the 2nd differences are constant.

First differences between successive y-values: -7, -5, -3, -1, 1, 3

Second differences between successive first differences: 2, 2, 2, 2, 2.

A function that can represent the area that can be enclosed in terms of x is 40x-x².

Given that Eighty meters of fencing is available to enclose the rectangular garden of Mang Gustin.

Area is defined as the amount of space that can be used within a flat surface or the surface of a solid. Perimeter is defined as a continuous line that forms a boundary to define a two-dimensional shape.

Let the length of garden, l=x

and the given perimeter, p=80

As we know, perimeter of rectangle is P=2(l+b).

Now, we will substitute the values and find the value of b, we get

80=2(x+b)

Now, we will divide both sides by 2, we get

80/2=2(x+b)/2

40=x+b

Further, subtract x from both sides, we get

40-x=x+b-x

40-x=b

Now, we will find the area of rectangle by using the formula A=lb.

Substitute the values in above formula, we get

A=x(40-x)

A=40x-x²

Hence, the area that can be enclosed in terms of x is 40x-x².
