Step-by-step explanation:

Inequality given:

When solving we do steps:

At the second step both sides divided by a.

When a is positive the inequality symbol remains as is, when a is negative we have to divide both sides by -1 as well. This will reverse the inequality symbol.

Correct answer choice is B.

Answer:

a) y = k/x

7 = k/9

b) y = 3

Step-by-step explanation:

From the question, we are told that:

y is inversely proportional to x.

Mathematically:

y ∝ 1/x

y = k × 1/x

y = k/x

k = Constant of Proportionality

a) work out an equation connecting y and x

To find this Equation,

y = k/x

when y=7 x=9

Hence:

7 = k/9

b) work out the value of y when x=21

We find the value of k first

7 = k/9

k = 7 × 9

k = 63

Hence, the value of y when x=21

y = k/x

k = 63, x = 21

y = 63/21

y = 3

The value of x in the given diagram is 7cm.

The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

According to the given question.

We have a diagram in which we have two right angled triangles.

Now, in the upper right angled triangle

[tex]tan50 = \frac{0pposite side}{5}[/tex]

⇒ 1.19 = 0pposite side/ 5

⇒ opposite side = 1.19 × 5

⇒ opposite side = 1.2 × 5

⇒ opposite side = 6cm

Now, the opposite side w.r.t angle 50  degrees in the upper right angle triangle is a adjacent side w.r.t to angle 38 degrees in the lower right angle triangle.

So, in the lower right angle triangle.

[tex]tan38 = \frac{x}{adjacent side}[/tex]

⇒[tex]0.78 = \frac{x}{6}[/tex]

⇒ x = 0.78 × 6

⇒ x = 4.68

⇒ x = 7cm

Hence, the value of x in the given diagram is 7cm.

Answer:

If you aren't allowed to use calculators do (1280 - 128pi) but if you are do (877.876140341) Don't forget units in your work and answer.

Step-by-step explanation:

Volume of Rectangular prism = L*W*H = 8*10*16 = 1280in

Volume of Cylinder = pi*r^2*H = 8*pi*r^2

We know that the diameter is 8 (because that's the height of the rectangular prism as stated in the question) and diameter is 2*r thus the radius of the cylinder is 4.

therefore the volume of the cylinder is 8*pi*(4)^2 which is 128pi If you aren't allowed to use calculators do (1280 - 128pi) but if you are do (877.876140341)

Step-by-step explanation: too lazy

Answer:

m = 2 and n = -10

Step-by-step explanation:

The given function is f(x) = x² + 4·x - 6

The form in which f(x) is to be written = (x + m)² + n, which is the standard form of a quadratic equation

We have;

f(x) = x² + 4·x - 6 = x² + 4·x + 4 - 6 - 4

f(x) = x² + 4·x + 4 - 6 - 4 = (x + 2)² - 10

f(x) = (x + 2)² - 10

By comparison with (x + m)² + n, we have;

m = 2, and n = -10

The midpoint of all the numbers are given below.

A location that is halfway between two other points is considered to be a line segment's midpoint. The distance between the midway and each endpoint is the same.

We have to find the midpoint of numbers.

a) 16 and 38

16 + 38 = 54/2 = 27

b) 259 and 361 = 620/2 = 310

c) 1004 and 2012 = 1508.

Answer: 3 times 9 is 27

Step-by-step explanation:

Answer:

25

Step-by-step explanation:

Given,

Measurement of <1 = x + 10

Measurement of <2 = 4x + 5

Also, said in the question that both these angles are complementary.

Therefore, by the problem,

<1 + <2 = 90°

=> x + 10 + 4x + 5 = 90

=> x + 4x + 10 + 5 = 90

=> 5x + 15 = 90

=> 5x = 90 - 15 = 75

[tex] = > x = \frac{75}{5} [/tex]

=> x = 15

Now, we have got the value of x so,

Measurement of <1 is

<1 = x + 10 = 15 + 10 = 25 (Ans)
