somebody please answer only 11. and 13. ANSWER QUICKLY

Answers

11. y=x+4
13. y=1/4x +1

Answer:

Step-by-step explanation:

y=mx+b where m is the slope and b is the y intercept, value of y when x=0

11.

Since we are given the point (0,4) we already know that b=4

slope is m=(y2-y1)/(x2-x1), using our two points (0,4)(-1,3) we have

m=(3-4)/(-1-0)

m=-1/-1=1 so the line is

y=x+4

12.

Again they gave us point (0,1) so we know b=1, from points (0,1)(4,2) we find

m=(2-1)/(4-0)

m=1/4 so our line is

y=x/4+1 (or more neatly)

y=(x+4)/4

She can jog 4,000 feet in 8 minutes.

Step-by-step explanation:

Find out how many feet she jogs in 1 minute.

6 minutes = 3000

1 minute = 3000 ÷ 6 = 500

8 minutes = 500 x 8 = 4000

3000 feet / 6 minutes = 500 feet per minute
8 minutes x 500 feet per minute = 4000 feet in 8 minutes

What interval consists of all $u$ such that neither $2u$ nor $-20u$ is in the interval $(-\infty,-1)$ ?

Answers

Answer:

[-1/2,1/20]

Step-by-step explanation:

Answer:

[-1/2,1/20]

Step-by-step explanation:

In terms of inequalities, we are asked to find all $u$ such that $2u\ge -1$ and $-20u\ge -1$.

The solution to the first inequality, obtained by dividing both sides by $2$, is $u\ge -\frac{1}{2}$.

We can solve the second inequality by dividing both sides by $-20$, but because we are dividing by a negative number, we must reverse the direction of the inequality: $u\le \frac{1}{20}$.

The set of $u$ which satisfy both inequalities simultaneously is thus $\boxed{\left[-\frac{1}{2},\frac{1}{20}\right]}$.

Sebastion's pan has the length of 10/3 inches, a width of 8/4 inches and a height of 3/2 inches. What is the volume of her pan

Answers

Answer:

10 in³

Step-by-step explanation:

Length = 10/3 inches

Width = 8/4 inches = 2 inches

Height = 3/2 inches

Volume = Length * width * height

Volume = 10/3 * 2/1 * 3/2

Volume = (10*2*3) / (3*1*2)

Volume = 60/6

Volume = 10 in³

a man makes a profit 15% by selling an article for rs.250. for what amount should he sell it to make profit of 38%​

Answers

Answer:

$300

Step-by-step explanation:

original price = $250

the profit= 15%

ok now let the cost price of article be ₹ x

x + 15% of x = 250

1.15x = 250 => 115x ÷ 100 = 250

115x = 25000 => x = 25000 ÷ 115

x = 5000/ 23

cost price of article = ₹5000/ 23

required profit = 38%

= 38% of 5000/ 23 = 0.38 × 5000/ 23

= 1900/ 23

the required will be selling price to gain about 38%

= cost price + required profit which is

= (5000/ 23) + (1900/ 23)))

= 6900/ 23 = $300

Answer:  now its required selling price = $300

The graph of f is given. How are f and g(x) = 2 cos(πx) different?

Answers

Answer:Same amplitude: 2,

but the period is half in the second case. Period of the first one is 2, in the second one is 1, so it will oscillate twice as many times than the first one, but it will go from -2 to 2, both of them

Hope it helps

Step-by-step explanation:

The period of function f(x) is 4 while the period of g(x) = 2 cos(πx) is 2 hence this is difference.

What is a period of any function?

The period of the function is the interval between repetitions of any function. A trigonometric function's period is typical of one whole cycle. As a preliminary step, we could use x = 0 for just any trigonometry curve function.

In another word the period of any function is the interval by which the function will going to get the same value as other with respect to changing variable.

Given that the function is f(x) has period 4 which can be observed by looking at the function.

If you look at function f(x) then you will notice after 4 intervals it is going to repeat itself.

And the period of g(x) = 2 cos(πx)  is 2 which can be calculated by several methods either graphical or mathematical.
