Answer:

A) up 5 units

Step-by-step explanation:

Given

See attachment for grid

Required

Which places ABCD in a quadrant

Considering vertical movements

From the x-axis, the distance between each point and the line of the x-axis is (the y coordinates):

[tex]A = -4[/tex]

[tex]B =3[/tex]

[tex]C = 7[/tex]

[tex]D = -2[/tex]

Considering the highest magnitudes in the positive and negative column, we have:

[tex]A = -4[/tex] and [tex]C = 7[/tex]

[tex]A = -4[/tex] means that a upward movement by (4 + 1) units will move ABCD completely in a quadrant;

[tex]4 + 1 = 5[/tex]

Hence, 5 units upward -- This represents option (a)

[tex]C = 7[/tex] means that a downward movement by (7 + 1) units will move ABCD completely in a quadrant

[tex]7 + 1 = 8[/tex]

Hence, 8 units downward

Consider horizontal movements

From the y-axis, the distance between each point and the line of the x-axis is (the x coordinates):

[tex]A = -8[/tex]

[tex]B = -6[/tex]

[tex]C = -3[/tex]

[tex]D =-2[/tex]

Considering the highest magnitudes in the positive and negative column, we have:

[tex]A = -8[/tex]

[tex]A = -8[/tex] means that a left movement by (8 + 1) units will move ABCD completely in a quadrant;

[tex]8 +1 = 9[/tex]

Hence, 9 units upward

(a) answers the question

For this one it’s 3/4. (Positive since it’s going up and you can’t simplify it anymore).

Answer:

aₙ = -2aₙ₊₁

Step-by-step explanation:

According to the sequence given 16, -8, 4, ...

a1 = 16

a2 = -8

a3 = 4

From the values, we can conclude thst;

a1 = -2(-8)

Since a2 = -8, then;

a1 = -2(a2)

Similarly

a2 = -2(4)

a2 = -2a3

The subsequent sequence are;

a3 = -2a4

The nth term will ne;

aₙ = -2aₙ₊₁

Hence the required recursive function is aₙ = -2aₙ₊₁

The recursive formula for the given sequence is

[tex]a_{n}=-\frac{1}{2} (a_{n-1})\\[/tex]

Given :

The terms of the sequence are  16, -8, 4, ...

Lets find the difference between the terms

[tex]-8-16=-24\\4-(-8)=12[/tex]

There is no common difference. So this is not an arithmetic sequence

Now we check common ratio'

[tex]\frac{-8}{16} =-\frac{1}{2} \\\frac{4}{-8} =-\frac{1}{2} \\[/tex]

The common ratio is -1/2

Now we write recursive formula

[tex]a_{n}=r(a_{n-1})[/tex]

Where 'r' is the common ratio

[tex]a_{n}=r(a_{n-1})\\a_{n}=-\frac{1}{2} (a_{n-1})\\[/tex]

The recursive formula is

[tex]a_{n}=-\frac{1}{2} (a_{n-1})\\[/tex]

Answer:

The value of x = 36°, while the value of y = 72°.

Step-by-step explanation:

All of these angles add up to 360°.

Opposite angles are always equivalent, so the angle opposing x would be 36°, which means x = 36°.

360 - 2(36) = 288

288/4= 72

To check:

(72 * 4) + 2(36) = 360

Answer:

900

Step-by-step explanation:

First, we set up our equation: To find the area of a trapaziod, the equation is Base 1+ Base 2 times Height

So, the equation would be: A=26+46x19

A=72x19

72 times 19= 900

Hope this helps and have a nice day!

Answer:

17. See below

18. 750

Step-by-step explanation:

17. Since the lollipops are being sold at the same price, 50 cents, for each one sold, they make a constant amount of money. For each increase in lollipops sold, there is a constant increase in money made, and thus the situation is a linear function.

18. To solve this equation, let's say y is the money made at the convention in dollars and x is the number of lollipops sold. If the principal gave them 125 dollars before they sold any lollipops (0 lollipops sold), then 125 is the y-intercept of the function, and in the equation y=mx+b, b=125. If each lollipop costs 50 cents (half of a dollar), then for each lollipop, x, sold, .5 dollars are made and are added to the profit, y. Thus, .5 dollars is the slope. The equation then becomes:

[tex]y=0.5x+125[/tex]

Now, if they need 500 dollars, y is thus equal to 500 dollars. Solving the equation:

[tex]500=0.5x+125[/tex]

[tex]500-125=0.5x[/tex]

[tex]375=0.5x[/tex]

[tex]\frac{375}{0.5} =x[/tex]

[tex]375*2=x[/tex]

[tex]750=x[/tex]

Thus, 750 lollipops must be sold.

Answer:

18.326 inches

Step-by-step explanation:

The question is basically asking us to find the arc length that the tip of the minute hand travels. The formula for an arc length is S=θr. So we need th find the angle that the minute hand passes through. We know that there is 360 degrees in a cicle and there is 12 stops around a clock, so divide 360 by 12 to find the degrees the minute hand travels every 5 minutes. We ge that every 5 minutes the hand travels 30 degrees, and 35 minutes is 7*5 so we multiple 30*7 to find the angular displacement, and we get 210 degrees. This equation uses radians though so we have to convert, which can be done doing [tex]\frac{210}{1} *\frac{\pi }{180}[/tex], and we ge that θ is [tex]\frac{7\pi }{6}[/tex] so ([tex]\frac{7\pi }{6}[/tex])(5)= 18.326 inches

Answer:

75.39 in^2

Step-by-step explanation:

circumference=2πr

30.8=2(3.14)r

30.8=6.28r

4.9=r

Now that we know the radius, we can plug it in for the area equation

area=πr^2

area=(3.14)(4.9)^2

area=(3.14)(24.01)

area=75.39 in^2
