If a line has a slope of 2 and contains the point (-2, 1) what is the equation in point slope form

Mathematics
1 answer:
Elden [556K]3 years ago
4 0

Answer:

y - 1 = 2(x + 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 2 and (a, b) = (- 2, 1), thus

y - 1 = 2(x - (- 2)), that is

y - 1 = 2(x + 2) ← in point- slope form

Adult male heights are normally distributed with a mean of 70 inches and a standard deviation of 3 inches. The average basketbal
sweet-ann [11.9K]

Answer: First Option is correct.

Step-by-step explanation:

Since we have given that

Mean (\mu)= 70 inches

Standard deviation (\sigma)= 3 inches

Average basket ball player (\bar{X}) = 79 inches

Since it is normally distributed assume with 5% significance .

So, it becomes,

Z>\frac{\bar{X}-\mu}{\sigma}\\\\Z>\frac{79-70}{3}\\\\Z>\frac{9}{3}\\\\Z>3\\\\\therefore\ P(Z>3)=1-0.9987=0.0013

At 0.05 level of significance , 0.0013 = 0.13% of the adult male population is taller than the average basketball player .

Hence, First Option is correct.

A circular cardboard piece is needed for the base of a volcano model. The volcano is 46 centimeters tall and has a volume of 800
Alenkinab [10]
For this case we can model the problem as a cylinder.
 The volume of a cylinder is given by:
 V = Ab * h

 Where,
 Ab: base area
 h: cylinder height
 Substituting values in the equation we have:
 800 = Ab * 46

 From here, we can clear the area of the base
 Answer:
 
An equation that can be used to find the area of the circular base is:
 
800 = Ab * 46

If a water tank already contains 55 gallons of water when baxter begins to fill it and water is flowing in at a rate of 8 gallon
saw5 [17]

Answer:

I think it would be 55+8x. I hope this helps. :)

Step-by-step explanation:

55 gallons of water

8 gallons per minute

It would be 55 gallons (the original amount in the tank) plus 8 gallons per minute. (8x)

x = how many minutes the tank is being filled up more.

so if you were to fill up the tank another 5 minutes, the equation would be 55+8(5)

55+40

95 would be the answer.

If M <1 = 115 degrees what is m <2
SIZIF [17.4K]

Answer:

M<2= 65

Step-by-step explanation:

The reason it is 65 because 2 angles add up to either 90 or 180 and in this case it would be 180.

You would use angle addition postulate to find the answer so M<1 + M<2 = 180.

Since M<1 is 115 you would substitute it into the formula so 115 + M<2 = 180

Then you would subtract 115 from 180 in which you would get M<2 = 65

Ted and Robin each gave a basket of green apples to their friend Lily. Ted’s basket contains 5 apples, each weighing ounces. Rob
Blababa [14]

<u>Question</u>:

Ted and Robin each gave a basket of green apples to their friend Lily. Ted’s basket contains 5 apples, each weighing 7 1/4 ounces. Robin’s basket contains 6 apples, each weighing 6 1/2 ounces. Whose basket is heavier and by how much?

<u>Answer</u>:

Robin’s basket is heavier than Ted’s basket  by  2.75 ounces

<u>Step-by-step explanation:</u>

<u>Given</u>:

Ted’s basket contains  = 5 apples

Weight of each apple in Ted’s basket = 7 1/4 ounces

Robin’s basket contains  = 6 apples

Weight of each apple in Robin’s basket =  6 1/2 ounces

<u>To Find:</u>

Whose basket is heavier and by how much?

<u>Solution:</u>

<u>Step 1: Finding the weight of Ted’s basket </u>

Weight of Ted’s basket  = Number of apple in the basket X  Weight of each apple

Weight of Ted’s basket  = 5 \times 7\frac{1}{4}

Weight of Ted’s basket  = 5 \times \frac{29}{4}

Weight of Ted’s basket  = \frac{145}{4}

Weight of Ted’s basket  =  36.25 --------------------------------(1)

<u>Step 2: Finding the weight of Robin’s basket </u>

Weight of Robin’s basket  = Number of apple in the basket X  Weight of each apple

Weight of Robin’s basket  = 6 \times 6\frac{1}{2}

Weight of Robin’s basket  = 6 \times \frac{13}{2}

Weight of Robin’s basket  = \frac{78}{2}

Weight of Robin’s basket  = 39 ounces--------------------------(2)

<u>Comparing equation (1) and (2)</u>

39 - 36.25 = 2.75 ounces

Weight of Robin’s basket  >  Weight of Ted’s basket
