Answer: Slope=5

Step-by-step explanation:

To find the slope of the line with 2 given points, you use the formula $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$ .

We plug our points into the formula and get:

$\frac{12-7}{5-4} =\frac{5}{1} =5$ .

Our slope is 5.

If cos A = k, then the value of the expression (sin A)(cos A)(tan A) is equivalent to:

sukhopar [10]

Answer:

1-k^2

Step-by-step explanation:

tan A= sin A/cos A

(sin A)(cos A)(sin A/cos A)=(sin A)^2

(sin A) ^2 + (cos A) ^2= 1

(sin A) ^2=1-(cos A) ^2

(sin A)^2= 1 - k^2

I think of a number, double it and add eleven. I get twenty five. Using the statement above form an equation using the letter x!

Wittaler [7]

Answer:

2x + 11 = 25

x = 7

Step-by-step explanation:

Let the number be x.

Double of x and add 11 equals 25.

2x + 11 = 25

Solve the equation.

2x + 11 = 25

Subtract 11 on both sides.

2x = 25 - 11

2x = 14

Divide 2 on both sides.

x = 14/2

x = 7

How long does a car traveling at 70 mph take to travel 88 miles, in hours

dybincka [34]

So,

Obviously, the car will travel 70 miles in one hour. So after one hour, the car will have traveled 70 miles. That leaves 18 miles.

The time it will take for the car to go another 18 miles will be 18 divided by 70.
$\frac{18}{70}$

Simplify.
$\frac{2*3*3}{2*5*7}$
$\frac{3*3}{5*7}$
$\frac{9}{35}$

Divide.
≈ 0.25714

So a car traveling at 70 mph will take approximately 1.25714 hours or 1.26 hours to travel 88 miles.

A certain kind of bacteria growing on your kitchen counter doubles every 30 mins.. Assuming that you start with only one bacteri

natali 33 [55]

What you can do is start with the key details in it... the main ones are that the bacteria grows every 30 minutes, you start with 1 bacteria, and the end time is 180 minutes. Basically you know that 3 goes into 18 6 times so 30 goes into 180 6 times which means that if you started with 1 bacteria you will end up with 7. Understand?
