A number that, when multiplied with another number, yields a result of 1 is called its multiplicative ____.

Answer:

The number is 20

Step-by-step explanation:

Step 1:  Convert words into an expression

5 less than a number is 15

5 less than a number is n - 5

n - 5 = 15

Step 2:  Add 5 to both sides to get the number

n - 5 + 5 = 15 + 5

n = 20

Answer:  The number is 20

Answer:

[tex]y=\frac{3}{31} x[/tex]

Step-by-step explanation:

Written in: y = mx + b

Answer:

y = 3/31x

Step-by-step explanation:

Step 1:  Add 30y to both sides

3x - 30y + 30y = y + 30y

3x = 31y

Step 1:  Divide both sides by 31

3x / 31 = 31y / 31

y = 3/31x

Answer:  y = 3/31x

Answer:

x = -2 0r x = 6

Step-by-step explanation:

from the question

X² – 4x – 12=0

solve by completing the square method

we have;

X² – 4x – 12=0

X² – 4x = 12

to make the left hand side a perfect square we add 4 to both sides.

X² -4x  + 4 = 12 + 4

X² -4x  + 4 = 16

from left hand side X² -4x  + 4

= (x -2) × ( x -2)

it can be simply expressed as

( x-2)²

so since X² -4x  + 4  has been simplified to be ( x-2)²

then,

( x-2)² = 16

x - 2 = √ 16

since square root has  two values it can either be positive or negative

so we have

x = 2 + √16

or

x = 2 - √16

therefore

x = 2 + √16

x = 2 + 4

x = 6

x = 2 - 4

x = -2

Option A: [tex]y=-\frac{1}{2} x+5[/tex] is the equation of the line.

Explanation:

It is given that the equation has a slope is [tex]m=-\frac{1}{2}[/tex]

It also contains the point [tex](8,1)[/tex]

We need to find the equation of line in slope - intercept form.

First, we shall determine the value of y - intercept(b).

Let us substitute the slope [tex]m=-\frac{1}{2}[/tex] and the point [tex](8,1)[/tex] in the slope - intercept form [tex]y=mx+b[/tex] , we get,

[tex]1=-\frac{1}{2} (8)+b[/tex]

Simplifying, we have,

[tex]1=-4+b[/tex]

Adding both sides of the equation by 4, we have,

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

     [tex]5=b[/tex]

Thus, the y - intercept is [tex]b=5[/tex]

Now, substituting the slope [tex]m=-\frac{1}{2}[/tex] and the y - intercept [tex]b=5[/tex] in the slope - intercept form [tex]y=mx+b[/tex] , we get,

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

Thus, the equation of the line is [tex]y=-\frac{1}{2} x+5[/tex]

Hence, Option A is the correct answer.

Answer:

The length of ZY to be a tangent is 15.

Option B is the correct answer.

A circle is a two-dimensional figure with a radius and circumference of 2pir.

The area of a circle is pir^2.

We have,

XY = Radius

And,

Radius = 8

Applying the Pythagorean theorem,

XZ² = XY² + ZY²

8² = (8 + 9)² + ZY²

64 = 289 + ZY²

ZY² = 289 - 64

ZY² = 225

ZY = 15

Thus,

The length of ZY is 15.

To solve this problem, we simply must plug in the values.

gz/g + z ⇒ [tex]\frac{12(9)}{12}[/tex] or 9.

When we plug in 12 for g and 9 for z, we will find that option C is correct.

Graph B is the only straight line, thus the linear function of x and the correct option is B.

A linear function is a function whose graph is a straight line. This means that for any two points on the graph, the change in y divided by the change in x is always the same.

Looking at graph B, we can see that the line is perfectly straight. This means that the change in y divided by the change in x is always the same, regardless of where we are on the line.

Therefore, graph B is a linear function of x.

Graphs A, C, and D are not linear functions of x. Graph A is a quadratic function, meaning that its graph is a parabola. Graph C is a piecewise function, meaning that its graph is made up of two different lines. Graph D is an exponential function, meaning that its graph curves upward.

Therefore, the correct option is B.

Answer:

7/4

Step-by-step explanation:

The slope of Q is (9-5)/(3-10) = -4/7

Perpendicular lines' slopes are opposite reciprocals of eachother (so the +/- changes and then x/y becomes y/x).

This means the slope of R is 7/4

The required slope of line R will be 7/4.

Perpendicular lines are two lines that cross one other and create a 90-degree angle.

Two lines are perpendicular if the product of their slopes is -1.

The line Q is given which passes through points (3,9) and ( 10,5)

Let

x₁ = 3,  y₁ = 9

x₂ = 10, y₂ = 5

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Substitute values in the formula

The slope of line Q will be:

m = (9-5)/(3-10)

m = -4/7

Since line R is perpendicular to Q, so the slope of line R will be

⇒ -1/m

⇒ -1/(-4/7)

Reciprocal the term in the denominator,

⇒ -1 × -7/4

Apply the multiplication operation, and we get

⇒ 7/4

Therefore, the required slope of line R will be 7/4.

Answer:

(i) The length of AH is 7.3784 m

(ii) The length of HC is 10.9389 m

Step-by-step explanation:

The sum of the angles ABC, BAC and ACB is 180º, hence, ACB = 180-90-56 = 34º. Note also that AH breaks the rectangle triangle ABC into 2 rectangle triangles AHB and AHC.

i) In AHB, AB is the hypotenuse, and the angle ABH is equal to ABC, hence it is 56º. AH is the opposite side of that angle and we know that

Sin(ABH) = opposite/hypotenuse = AH/8.9

Thus,

AH = 8.9*Sin(ABH) = 8.9*Sin(56º) = 7.3784 m

ii) In AHC, AH is also the opposite of the angle ACH (which meassures 34º), and HC is the adjacent of that angle (the hypotenuse is AC). As a result

Tan(ACH) = Tan(34º) = 0.6745 = opposite/adjacent = AH/HC = 7.3784/HC

Hence,

HC = 7.3785/0.6745 = 10.9389 m

Final answer:

AH = 8.9 m, HC = 0 m

Explanation:

Given that triangle ABC is right-angled at A, we can use trigonometry to find the lengths of AH and HC.

To find the length of AH, we can use the sine of angle BAC:

AH = AB * sin(BAC) = 8.9 * sin(90°) = 8.9

Since AH = 8.9 m, we can find the length of HC by subtracting AH from BC:

HC = BC - AH = 8.9 - 8.9 = 0 m

The stock purchased for $77 grew by 17.9%, which equals an increase of $13.78. Therefore, the current stock price is $90.78.

To solve this problem, we need to calculate the percent increase of the stock's price. A percent increase of 17.9% means that the stock price has increased by 17.9% of the original price. To calculate the amount of the increase, we multiply the original price ($77) by the percent increase (17.9%), remembering to convert the percentage to a decimal (0.179).

So, $77 times 0.179 equals ~$13.78. This is the amount by which the stock price has increased. To find the new price of the stock, we add this increase to the original price, which gives us $77 (Original price) + $13.78 (Increase) = $90.78, so the stock is worth $90.78 now.

Step-by-step explanation:

[tex]r^{}} = \sqrt{\frac{V}{\pi h }[/tex] is the equation correctly shows the radius.

Option B

Step-by-step explanation:

The cylinder’ volume (density) indicates how much amount of materials it can able to carry or how much amount of material it can immerse in it. The formula for volume of cylinder is given as:

                      [tex]V = \pi r^{2}h[/tex]

where

V = volume of cylinder

r = radius of cylinder

h = height of cylinder

In order to find radius following simplifications are done:

⇒[tex]V = \pi r^{2}h[/tex]

Keep the factor 'r' in one side and keep other in one side as below,

⇒ [tex]\frac{V}{\pi h } = r^{2}[/tex]

Taking square root on both sides,

⇒[tex]\sqrt{r^{2}} = \sqrt{\frac{V}{\pi h }[/tex]

⇒[tex]r^{}} = \sqrt{\frac{V}{\pi h }[/tex]

Therefore, option b is correct as [tex]r^{}} = \sqrt{\frac{V}{\pi h }[/tex].

Answer:

X=32 and Y=12

The two numbers are 32 and 12

Step-by-step explanation:

Let the number be represented by X and Y

X = 20 + Y-------- equation 1

3X - Y = 84------- equation 2

solving the equation by substitution;

we substitute equation 1 into equation 2, we have;

3(20+Y)-Y = 84

expanding the bracket;

60 + 3Y - Y = 84

60 + 2Y = 84

2Y = 84 - 60

2Y = 24

divide both sides by 2;

2Y/2 = 24/2

Y = 12

from equation 1, we can find X by using the value of Y;

X = 20 + Y

X = 20 + 12

X = 32

PROOF:

using equation 2;

[3*32]-12=84

96-12=84

84=84
