Answer:

-1/2, 7

Step-by-step explanation:

Given the expression

(x -7)(-4x -2)=0

This means that;

x - 7  = 0 and -4x - 2 = 0

x = 0+7 snd -4x = 2

x = 7 and x =  -2/4

x = 7 and -1/2

Hence the solution from least to greatest is -1/2, 7

Answer:

Each angle is 60 degrees

Step-by-step explanation:

The sides of the triangle are equal, which means the angles are equal. Since the sum of the interior angles of a triangle are 180 degrees, each angle is 180/3 = 60 degrees.

Complete question:

A wheel of radius 10 cm is turning at a rate of 5 revolutions per minute.

Calculate  the angle subtended at the centre by the minor arc after 1 second.

Answer:

the angle subtended at the centre by the minor arc is 30⁰

Step-by-step explanation:

Given;

radius of the wheel, r = 10 cm = 0.1 m

angular speed of the when, ω = 5 rev/min

duration of the motion, t = 1 second

Determine the angular speed in radian per second,

[tex]\omega = 5\ \frac{rev}{\min} \times \frac{2\pi \ rad}{1 \ rev} \ \times \frac{1 \min}{60 \ s} = \frac{10\pi \ rad}{60 \ s} = \frac{\pi }{6} rad/s[/tex]

After 1 second, the angular distance turned by the wheel is calculated as;

[tex]\theta = \omega t\\\\\theta = \frac{\pi \ rad} {6 \ s} \times 1 \ s\\\\\theta = \frac{\pi } {6 } \ rad\\\\in \ degrees; \theta = \frac{\pi \ rad}{6} \times \frac{180^0}{\pi \ rad} = \frac{180^0}{6} = 30^0[/tex]

Therefore, the angle subtended at the centre by the minor arc is 30⁰

Answer:

B

Step-by-step explanation:

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then a shift to the right of a units

Here f(x) is shifted 4 units to the right , so

g(x) = | x - 4 |

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here f(x) is shifted 6 units up , so

g(x) = | x - 4 | + 6 → B

The simplified equation for the new function is g(x) = |x - 4| + 6.

It is the movement of the shape in the left, right, up, and down directions.

The translated shape will have the same shape and shape.

There is a positive value when translated to the right and up.

There is a negative value when translated to the left and down.

We have,

The absolute value parent function is f(x) = |x|.

To shift 4 units to the right, we replace x with (x - 4) since we want the graph to move 4 units to the right.

To shift 6 units up, we add 6 to the entire function since we want the graph to move 6 units up.

So the equation of the new function g(x) is:

g(x) = |x - 4| + 6

Thus,

The simplified equation for the new function is g(x) = |x - 4| + 6.

Answer:

1

Step-by-step explanation:

So what is slope?

Slope is the change in y over the change in x.

You find the change in y and x when you compare two points on the line.

In this case, lets chose the two points they give us:

(1, -4) and (6, 1)

What is the difference of y? That looks like 5(1+4) or (1--4).

What is the difference of x? That looks like 5(6-1=5)

So we can tell the slope is y/x, or 5/5.

This can simpfly to 1.

So 1 is your slope!

Answer:

[tex]f'(y) = -9e^{-9y}[/tex]

Step-by-step explanation:

The given function is :

[tex]f(y) = 8 + e^{-9y}[/tex]

We need to find the value of f'(y).

[tex]f'(y)=\dfrac{d}{dy}[8+e^{-9y}][/tex]

[tex]=\dfrac{d}{dy}(8)+\dfrac{d}{dy}(e^{-9y})\\\\=0+e^{-9y}\dfrac{d}{dy}(-9y)\\\\=-9e^{-9y}[/tex]

So, the value of f'(y) is equal to [tex]-9e^{-9y}[/tex].

Answer:

  x-intercept: 7/6

Step-by-step explanation:

The x-intercept is found by solving for x when y=0.

  0 = 6x -7

  7 = 6x . . . . . add 7 to both sides of the equation

  7/6 = x . . . . divide both sides by 6

The x-intercept is 7/6 = 1 1/6 ≈ 1.167.

__

The y-intercept is the constant in the given equation: -7. The slope of 6 tells you the line rises 6 units for 1 unit to the right. So, the point (1, -1) is another point on the graph. The line through those two points, (0, -7) and (1, -1), will intersect the x-axis at x=7/6.

The base of the parallelogram formed from the circle is half the circumference or πr .

A circumference is the length of the circle which is the perimeter of the circle.

The circumference of the circle can be given by the formula C = 2πr , where r is the radius of the circle.

If a circle is divided into equal sectors then the approximate size of the polygon formed by rearranging the sectors is a parallelogram.

The base of the parallelogram will be half of the circumference , or

base = 0.5 × 2 πr = πr

And the height will be the radius r of the circle.

Now area of a parallelogram is given by  base × height

Now area = πr × r = πr²

Therefore the area of the circle is πr² .

Hence the base of the parallelogram formed from the circle is half the circumference or πr .
