14 cm perimeter of circle​

Answers

Answer 1

Step-by-step explanation:

Radius = 14 cm

π = 22/7 (Because the value of the circle's radius is the multiples of 7).

• Perimeter :

= 2 . π . r

= 2 . 22/7 . 14

= 28 . 22/7 (Divide 28 and 7 with 7)

= 4 . 22/1

= 4 . 22

= 88 cm is the answer

2. Given the equation of a line, y = 1/5x, the slope is:

Answers

Answer:

1/5

Step-by-step explanation:

The slope-intercept form looks like [tex]y=mx+b[/tex] where b is the y-intercept and m is the slope. m is the slope because if you increase x by 1, the value y increases by m, and if you increase x by 1 again, the y-value will increase by the value of m, because it's being multiplied. b is the y-intercept since the y-intercept is when x=0 so mx will become m(0) which is just 0 leaving b by it self. In this case you have y=1/5x so if you were to start with 0 as x the value of y is 0. Now increase it by 1 so x becomes 1, the value of y becomes 1/5x, now increase it by 1 again so x becomes 2, the value of y is 2/5x, so as you can see the function is just increasing by 1/5 so that's the slope, so essentially whatever the coefficient of x is (the number in front of the variable x), is the slope

Given:  [tex]\textsf{y = 1/5x}[/tex]

Find: [tex]\textsf{The slope of the line}[/tex]

Solution:  In order to determine the slope of the line we need to see how the slope-intercept form compares to this expressions.  The slope-intercept form is y = mx + b where m is the slope and b is the y-intercept.  In this case we have no y-intercept therefore we do not have a b. However, our slope is equal to 1/5 as it fits perfectly with the form that was provided.

Oy<(x+40) (x + 50)

Answers

Using the Factor Theorem, the inequality that represents the given region is:

[tex]y < \frac{(x + 40)(x - 50)}{21}[/tex]

What is the Factor Theorem?

The Factor Theorem states that a polynomial function with roots [tex]x_1, x_2, \codts, x_n[/tex] is given by:

[tex]f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)[/tex]

In which a is the leading coefficient.

The roots are given as follows:

[tex]x_1 = -40, x_2 = 50[/tex]

Hence:

y = a(x + 40)(x - 50)

It includes the point (-55,-75), hence:

-75 = a(-55 + 40)(-55 - 50)

a = 75/(15 x 105)

a = 1/21

Hence the region less than the equation is:

[tex]y < \frac{(x + 40)(x - 50)}{21}[/tex]

A particle is moving along a projectile path at an initial height of 80 feet with an initial speed of 112 feet per second. this can be represented by the function h(t) = −16t2 112t 80. what is the maximum height of the particle?

Answers

Answer:

276 feet

Step-by-step explanation:

The best way to do this is to complete the square, which puts the quadratic in vertex form. The vertex of a negative parabola, which is what this is, is the highest point of the function...the max value.  The k coordinate of the vertex will tell us that highest value.  To complete the square, we will first set the quadratic equal to 0, then move the constant over to the other side:

The rule for completing the square is that the leading coefficient must be a positive 1.  Ours is a negative 16, so we have to factor out -16:

Now the next thing is to take half the linear term, square it, and then add it to both sides.  Our linear term is 7, half of that is 7/2.  Squaring 7/2 gives you 49/4.  So we add 49/9 into the parenthesis on the left.  However, we can't forget that there is a -16 out front there that refuses to be ignored.  We have to add then (-16)(49/4) onto the right:

The purpose of this is to create a perfect square binomial that serves as the h value of the vertex (h, k).  Stating that perfect square on the left and doing the addition on the right:

Now we finalize by moving the constant back over and setting it back equal to y:

The vertex is

That translates to "at 3.5 seconds the particle is at its max height of 276 feet".

Jorge worked 6 hours of overtime this week but has decided to take time off instead of overtime pay. How many hours will Jorge receive in time off from work

Answers

Jorge will receive 9 hours in time off from work.

How many hours will Jorge get to take time off?

It is given that, Jorge has done overtime for 6 hours in this week. As per the Fair Labor Standards Act, for 6 hours of overtime work, he must be paid one and a half times the pay he gets per hour.

Instead of receiving an overtime pay for working 6 hours extra, Jorge decides to receive paid leaves from work, that is, he will get one and a half of the total hours for which he worked overtime.

As a result, the time off he receives from work = [tex]1\frac{1}{2} (6)[/tex] hours

[tex]=\frac{3}{2}(6) = 9 hours[/tex]

Thus, Jorge gets 9 hours in time off from work in return. The time that he earns for the overtime is equivalent to the pay he was supposed to receive for the overtime work.

 1)  1cm/10mm, or

 2) 10mm/1cm

We are given 136 mm.  Convert that by using either conversion factor.

(136mm)*(1cm/10mm) = 13.6 cm  Note how the mm unit cancels.

To use the other conversion factor, do a division:

(136mm)/(10mm/1cm) = 13.6 cm

Answer:

A. y<-1/5x+1

Step-by-step explanation:

First, find the slope of the line

delta y / delta x = slope (delta means "change in", so delta y would the the change in y)

the change in y is 1, and the change in x is -5, so the slope is -1/5

we now know that the equation of the line is
y=-1/5x+1

The answer can't be c or d, because the line is dotted and not solid (solid lines signify ≥ or ≤, and dotted > and <)
To test if it is > or <, we can plug in some numbers to see if the equation is true

Right now, we have:


y[?]-1/5x+1, where "[?]" is either > or <


we see that the point 0,0 is a solution, since it is in the shaded region of the graph, because of this, we know that if we plug x=0 and y=0 into the equation, it must be true

plug in:

0[?]-(1/5)*0+1

0[?]1

clearly, [?] should be <, as 0<1
so, now that we know [?], we can replace it in our equation

y<-1/5x+1 , or "A"

y = 8/x

Then the points (x, y) on the graph of the function are of the form:

32 less than 3/7 of a number is 11/35 of that number. Find the number.

Answers

Answer is x=280
Step by step
We know 32 less than is subtraction -32
We know 3/7 of a number is 3/7x
We know “is” is equal =
We know 11/35 of a number is 11/35x
So
3/7x - 32= 11/35x

Now solve by first by combining like terms
Change the denominator of 3/7 to match the other fraction so we can combine. 7x5=35 so we do the same to the numerator, 3x5.
3. 15
____. _____
7. 35

3/7x -32 = 11/35x
15/35x - 32 = 11/35x
Subtract 15/35x from both sides to combine like terms
-32 = -4/35x
Now divide both sides by -4/35 to solve for x
To divide a fraction flip it and multiply
( -35/4 )(-32)
X= 280

You can check your work by substituting your number for x into your equation

3/7 (280) -32 = 11/35 (280)
120 - 32 = 88
88 = 88

Answer:

Step-by-step explanation:

Let "a number" be x.

"3/7 of a number" means (3/7)x

"32 less" means - 32

Thus, "32 less than 3/7 of a number" means (3/7)x -32

"is 11/35 of that number" means = (11/35)x

Put these together and we get:

(3/7)x -32 = (11/35)x

(3/7)x - (11/35)x = 32   Rearrang to get the x on one side

We need to change "(3/7)x - (11/35)" so that the two terms have a common denominator.

If we multiply the first term by (5/5) [which is equal to 1], we get:  

(5/5)(3/7)x or

(15/35)x

We can now write:

(15/35)x - (11/35)x = 32

(4/35)x = 32

Multiply both sides by (35/4)

(35/4)(4/35)x = (35/4)(32)

x = (35)(8)

x = 280
