H varies directly to the cube of c. When H =40 c=2. find the value of when H=5000

Answers

Answer 1

Answer:

c = 10

Step-by-step explanation:

Given that H varies directly as c³ then the equation relating them is

H = kc³ ← k is the constant of variation

To find k use the condition when H = 40, c = 2 , then

40 = k × 2³ = 8k ( divide both sides by 8 )

5 = k

H = 5c³ ← equation of variation

When H = 5 000, then

5000 = 5c³ ( divide both sides by 5 )

1000 = c³ ( take the cube root of both sides )

[tex]\sqrt[3]{1000}[/tex] = c , so

c = 10

Answers

Given:

Consider the below figure attached with this question.

[tex]\angle ABO=20^\circ[/tex]

[tex]\angle ACO=30^\circ[/tex]

To find:

The value of x.

Solution:

Draw a line segment OA as shown below.

In triangle ABO,

[tex]OA=OB[/tex]      [Radii of same circle]

[tex]m\angle BAO=m\angle ABO=20^\circ[/tex]        [Base angles of an isosceles triangle]

In triangle ACO,

[tex]OA=OC[/tex]      [Radii of same circle]

[tex]m\angle CAO=m\angle ACO=30^\circ[/tex]        [Base angles of an isosceles triangle]

Now,

[tex]m\angle BAC=m\angle BAO+m\angle CAO[/tex]

[tex]m\angle BAC=20^\circ+30^\circ[/tex]

[tex]m\angle BAC=50^\circ[/tex]

Central angle is always twice of angle subtended by two points on the circle.

[tex]m\angle BOC=2\times m\angle BAC[/tex]

[tex]x=2\times (50^\circ)[/tex]

[tex]x=100^\circ[/tex]

Therefore, the value of x is 100°.

Answers

Answer:

The equation of the line that is perpendicular to y = -x – 10 and contains point (-12, 1)

[tex]y=x+13[/tex]

Please note there is something wrong with the  values given question. This is correct answer.

Step-by-step explanation:

Slope of line y = -x – 10 is m1=-1

Since slope of perpendicular lines are negative reciprocal of each other

Slope of other line is m2=1

Equation of line contains point (-12, 1) and having slope m2=1 is

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-1 = 1(x+12)[/tex]

[tex]y =x+12+1 \\y = x + 13[/tex]

Find the measure of the largest angle in the triangle shown . PLS HELP

Answers

Answer:

72°

Step-by-step explanation:

So the three angles of a triangle always add up to 180°. This means that

[tex]15x + 21x + 24x = 180[/tex]

This becomes:

[tex]60x = 180[/tex]

And solves as:

[tex]x = 3[/tex]

The largest angle has to be the one marked with 24x because it has the largest coefficient and x is a constant.

[tex]24x = 24(3) = 72[/tex]

The measure of the largest angle in the triangle is 72°.

72 degrees is the biggest angle in the given triangle.

What are the properties of the triangle?

The properties of the triangle are: The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.

Given that the three angles of the triangle are 24x, 21x, and 15x

Since the sum of all the angles of the triangle is always 180 degrees

Thus,

24x +21x + 15x = 180

60x = 180

x = 3

Thus, the biggest angle would be 24x

biggest angle of triangle = 24 * 3 = 72

Therefore, the biggest angle of the given triangle is 72 degrees

The slope of a ramp (or anything else) is the ratio of its "rise" to its "run."

The rise is the vertical change. Here, that is shown as 3 m.

The run is the horizontal change. Here, that is shown as 36 m.

Then the slope is ...

If this were a line on a graph, the slope would be calculated the same way. When the rise is positive to the right, the slope is positive. On a graph, if the rise is negative as you go to the right, the slope is negative.

The area of the garden is increased by 20 % . If the width remains the same, then the new length of the garden is 2.4 yards.

What is Area of Rectangle?

The area of Rectangle is length times of width.

Given that A decorative fence surrounds a rectangular flower garden that is 2 yards long and 3 yards wide

Area = Length × Width

Area=6 yards.

The area of the garden is increased by 20 % .

20/100=0.2

the area would equal 6 (l x w) and 6 increased by 20% equals 7.2.

As the width remains same

so we use 7.2/3 to find the new length

7.2/3=2.4 yards.

Hence, 2.4 yards is the new length of the garden.

i just need y intercept and equation

Answers

Answer:

Slope = 4y-intercept = -8

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

m is the slope b is the y-intercept

Given the table

x               y

2              0

7              20

Determining the slope between (2, 0) and (7, 20)

(x₁, y₁) = (2, 0)

(x₂, y₂) = (7, 20)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [20 - 0] / [7 - 2]

               = 20 / 5

               = 4

Thus, the slope of the line = m = 4

now substituting the point (2, 0) and the slope m = 4 in the slope-intercept form of a line equation to determine the y-intercept b.

[tex]y = mx+b[/tex]

0 = 4(2) + b

b + 8 = 0

subtract 8 from both sides

b + 8 - 8 = 0 - 8

b = -8

Thus, the y-intercept = -8

Summary:

Slope = 4y-intercept = -8

Answer:

B, C, D and E are correct options

Step-by-step explanation:

Here, we want to get the correct options;

a. We simply divide the next term by the previous term so that we get the common ratio

That would be 16/-8 = -32/16 = -2

As we can see, the common ratio is -2 which means that the option cannot be correct

b. The 5th term is mathematically;

ar^4 = -8 * (-2)^4 = -8 * 16 = -128

This is correct

c. The 7th term is

ar^6 = -8 * (-2)^6 = -512

5th term is ar^4 = -8 * (-2)^4 = -128

So -512/-128 = 4

As we can see, this option is correct

d. 8th term is 1024

8th term is ar^7

= -8 * (-2)^7 = 1024 which is correct

e. 10th term is ar^9 = -8 * (-2)^9 = 4096

9th term is ar^8 = -8 * (-2)^8 = -2048
