The equation of the horizontal line goes through the point (-1,8)is

Answers

Answer 1

Answer:

y = 8

Step-by-step explanation:

Parallel lines are lines which do not intersect. If the line is parallel to the x-axis then it is a horizontal line that intercepts the y-axis at the y-coordinate of the point (-1,8). So the equation of the line is y = b where b is the y-coordinate or y-intercept. Here it is y = 8.

how we make 17/24 smaller

Answers

Answer:um you simplify it

Step-by-step explanation:

Final answer:

To make the fraction 17/24 smaller, you can increase the denominator or decrease the numerator, but it will change the value of the fraction.

Explanation:

To make the fraction 17/24 smaller, you need to increase the denominator (the bottom number) or decrease the numerator (the top number).

One simple way to do this is to add a number to 24 making it 25, 26, 27, and so forth while keeping the numerator as 17. The larger the denominator, the smaller the fraction is. Alternatively, you could decrease the numerator to 16, 15, etc, while keeping the denominator at 24. Again, the smaller the numerator, the smaller the fraction.

Also remember that the fraction must remain proper or else it will become a whole number and eventually bigger than 17/24.

Please note that these changes alter the value of the fraction, and therefore might not be accurate representations of whatever the fraction 17/24 is supposed to represent.

A line passes through the point (5,-2) and has a slope of -1/3.Which equation models the line

Answers

Answer:

[tex]y + 2= -\frac{1}{3}(x-5)[/tex]

Step-by-step explanation:

To write the equation of a line with a slope and a point, use the point slope form of the line. Substitute m = -1/3 and (5, -2).

[tex]y - y_1 = m(x-x_1)\\y --2 = -\frac{1}{3}(x - 5)\\y + 2 = -\frac{1}{3}(x-5)[/tex]

You can convert to slope intercept form.

[tex]y + 2 = -\frac{1}{3}(x-5)\\y + 2 = -\frac{1}{3}x + \frac{5}{3}\\y = -\frac{1}{3}x + \frac{5}{3} -2\\y = -\frac{1}{3}x - \frac{1}{3}[/tex]

Write the standard equation of a circle with center (-4,0) and radius 3.

Answers

Answer:

(x+4)^2 + y^2 = 9

Answer:

The correct answer is first  option

(x + 4)² + y² = 9

Step-by-step explanation:

Formula:-

Let (x₁, y₁) and 'r' be the radius of a circle the equation of the circle is given by

(x - x₁)² + (y - y₁)² = r²

To find the equation of the circle

Here (x₁, y₁) = (-4, 0) and r = 3

we have,

(x - x₁)² + (y - y₁)² = r²

(x - -4)² + (y - 0)² = 3²

(x + 4)² + y² = 9

Therefore the equation of the given circle  is (x + 4)² + y² = 9

Determine the intercepts of the line y+1=3(x-4)

Answers

To find the intercepts, the other number will be 0 (x-intercept: when y is 0, and vise-versa).

So:

x-intercept: 0 + 1 = 3x - 12 -> 3x = 13 -> x = 13/3, so it will be ([tex]\frac{13}{3}[/tex], 0).

y-intercept: y + 1 = 3*0 - 12 -> y = -13, so it will be (0, -13).

Answer:

x-intercept = [tex]\frac{13}{3}[/tex]

y-intercept = [tex]-13[/tex]

Step-by-step explanation:

We are given the following equation of a line and we are to find the x and y intercepts for it:

[tex] y + 1 = 3 ( x - 4 ) [/tex]

To find the x-intercept, we will put in 0 for the y to get:

[tex] 0 + 1 = 3 ( x - 4 ) \\\\ 1 = 3 x - 12 \\\\ 3 x = 1 + 12 \\\\ x = \frac { 13 } { 3 } [/tex]

To find the y-intercept, we will put in 0 for the x to get:

[tex] y + 1 = 3 ( 0 - 4 ) \\\\ y + 1 = -124 \\\\ y = - 12 - 1 \\\\ y = - 13 [/tex]

So the x-intercept is [tex]\frac{13}{3}[/tex] while the y-intercept is [tex]-13[/tex].

B) $239.26
C) 200.10
D) $187.55

Answers

$95.225 X 2 = $190.45


The answer is A.$190.45

Answer:

Option A is correct answer.

Step-by-step explanation:

Per hour wage = $8.55

Number of hours in a week = 15

So, total pay of the week is = [tex]8.55\times15=128.25[/tex]

The biweekly salary becomes = [tex]128.25\times2=256.50[/tex]

Deductions are as follows:

FICA (7.65%), [tex]0.0765\times256.50=19.62[/tex]

Federal tax withholding (10.4%), [tex]0.104\times256.50=26.67[/tex]

State tax withholding (7.7%), [tex]0.077\times256.50=19.75[/tex]

Now adding all the deductions we get:

[tex]19.62+26.67+19.75=66.04[/tex]

Subtracting the deductions from the biweekly pay we have =

[tex]256.50-66.04[/tex]= $190.46

A store gives away gift bags during a sale. Of these gift bags, 30% are green, 20% are yellow, and 50% are blue. The average number of items in each green bag is 10. The average number of items in each yellow bag is 5. The average number of items in each blue bag is 8. What is the average number of items in all the gift bags? Enter your answer as a decimal in the box.

Answers

Answer:

8 items per bad

Step-by-step explanation:

30% are green and hold an average of 10,

20% are yellow and hold an average of 5

50% are blue and hold an average of 8,

all together they hold an average of ...

[0.3(10) + 0.2(5) + 0.5(8)]

[ 3 + 1 + 4] = 8 items on average

Say there's 10 total gift bags given out, then

3 of them will be green, each with 10 items for a total of 30 items,

2 of them will be yellow, each with 5 items, for a total of 10 items,

5 of them will be blue, each with 8 items, for a total of 40 items.

All together there are 10 bags, and 80 items, for an average of

80/10 = 8 items per bag

These numbers will stay the same no matter how many bags are given out

To calculate the average number of items in all gift bags, the weighted average of items per color category based on their percentage distribution is computed, resulting in an overall average of 8 items per bag.

The question asks to calculate the average number of items in all the gift bags given the percentages of green, yellow, and blue bags and their respective average items. To find the overall average, we can weight each average by the percentage of bags of that color.

Here is the calculation:

(30% of 10 items) for green bags: 0.30 times 10 = 3(20% of 5 items) for yellow bags: 0.20 times 5 = 1(50% of 8 items) for blue bags: 0.50 times 8 = 4

Summing these amounts gives us the overall average:

3 (from green bags) + 1 (from yellow bags) + 4 (from blue bags) = 8 items per bag on average.

A) 104.5 ft

B) 105.8 ft

C) 106.1 ft

D) 107.4 ft

E) 108.9 ft

Answers

Final answer:

To find the height of the tower given the angle of elevation and distance from the observer to the tower's base, the tangent function is used. The height is calculated as 28 feet multiplied by tan(75 degrees), resulting in approximately 105.8 feet.

Explanation:

The student is asking for help with a trigonometry problem involving the angle of elevation to calculate the height of a tower. In this case, we are given the angle of elevation as 75 degrees and the distance from Mindy to the base of the tower as 28 feet. To find the height of the tower, we use the tangent function, which is the ratio of the opposite side to the adjacent side in a right-angled triangle.

So, we have:
tan(75 degrees) = opposite/adjacent
tan(75 degrees) = height of tower/28 ft

Therefore, to find the height of the tower, we can write this equation as:
height of tower = 28 ft × tan(75 degrees)

By calculating this using a calculator, we find the height of the tower to be approximately 105.8 feet, which corresponds to option B.

I just taught you how to do this, it’s really simple, try it yourself! I’ll give instructions again.

Use the equation Y=mx+b where m represents the slope and b is the y-axis point.

Finding b is easiest, so we’ll do that first. Again, b is the y axis point. So where does the line cross the y axis? That is the vertical line on the graph. The line crosses at point (0,5) so 5 is your b value.

Next find your m value, or slope. The slope is simply rise/run. Which means start at the y axis value, and count how many places you need to go down to find a perfect triangle shape. You simple go down two points, and then over one point to reach a perfect triangle. Therefore since you go down 2, your rise is -2 and since you go over 1, your run is 1. Rise/run=-2/1, this simplified is just -2. So that is your m value.

Finally, plug these into y=mx+b and get your answer of

What is Intercept?

In mathematics, an intercept is the point at which a line, curve or surface intersects a coordinate axis. In the case of a two-dimensional Cartesian coordinate system, intercepts of a line are where the line intersects either the x-axis (horizontal axis) or the y-axis (vertical axis). The x-intercept is the point at which the line intersects the x-axis, and the y-intercept is the p

1. The Y-intercept of the quadratic function f(x) = 6x² - 3x + 1 is the value of f(0), which is the value of the function when x = 0. Therefore, we have:

f(0) = 6(0)² - 3(0) + 1 = 1

So the Y-intercept of the function is 1.

2. The axis of symmetry of a quadratic function given in vertex form, f(x) = a(x - h)² + k, is the vertical line x = h.

Therefore, for the given quadratic function f(x) = 4(x + 9)² - 5, the vertex is at the point (-9, -5), and the axis of symmetry is the vertical line x = -9.

3. Now, we can write the quadratic function in factored form as:

f(x) = 3(x-(-8))(x-3)

= 3(x+8)(x-3)

Therefore, the answer is (D) f(x)=3(x+8)(x-3).

4. We can complete the square to rewrite the quadratic function in vertex form:

f(x) = -2x² + 16x - 11

f(x) = -2(x²- 8x + 11/2)

f(x) = -2(x²- 8x + 16 - 16 + 11/2)

f(x) = -2((x - 4)² - 21/2)

f(x) = -2(x - 4)² + 21
