Answer:

Step-by-step explanation:

The slope formula is useful for this.

  m = (y2 -y1)/(x2 -x1)

__

First line:

  m = (-9 -(-9))/(9 -(-6)) = 0/15 = 0

The slope of the first line is zero.

__

Second line:

  m = (-5-1)/(4 -4) = -6/0 = undefined

The slope of the second line is undefined.

_____

It is always a good idea to apply a little critical thinking to the given information. Here, you observe that the y-coordinates of the first pair of points are the same. That means this is a horizontal line, with a slope of 0.

Similarly, you observe that the x-coordinates of the second pair of points are the same. That means this is a vertical line, with undefined slope.

Hello there! We're provided with two problems in one, but we can solve each of them by using the slope formula, which is this:

[tex]\stackrel\diamond{\boxed{\boxed{\bold{\frac{y_2-y_1}{x_2-x_1}}}}}[/tex]

In this formula,

Plug in the values:

So the slope is 0.

       <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

The second problem can be solved the same way!

Once again, we'll use the formula

[tex]\stackrel\diamond{\boxed{\boxed{\bold{\frac{y_2-y_1}{x_2-x_1}}}}}[/tex]

only this time, the values are different:

Plug in the values:

So the slope's undefined. I hope this helps, feel free to comment if you have any queries regarding the slope formula! ^^

Answer:

z = 7

Step-by-step explanation:

Based on the midsegment theorem of a triangle, the length of the midsegment of the triangle (z) = ½ of the length of the 3rd side of the triangle (14)

Thus:

z = ½(14)

z = 7

Answer:

1824in^2

Step-by-step explanation:

area of rectangle:

L x W = A

32 x 48 = 1539

area of triangle:

(L x W) / 2 = A

(48 x 12) / 2 = 288

add:

1539 + 288 = 1824in ^2

Answer:

Step-by-step explanation:

Answer: 12

Step-by-step explanation:

The volume of Larry’s picture is approximately 653in³

The volume of Sandra’s pitcher is approximately 905in³

The formula for calculating the volume of a cylinder is expressed as;

V = πr²h

Such that the parameters are;

Now, substitute the values, we have;

Larry's cylinder

Volume = 3.14 × 4² × 13

Find the square value and multiply the expression

Volume = 653in³

Sandra's cylinder

Volume = 3.14 × 6² × 8

Find the square value and multiply the expression

Volume = 905in³

Step-by-step explanation:

Answer:

Step-by-step explanation:

P varies jointly as q and r

p=k* q r

150 =k *(18)(5)

150 = k*(90)

150/90 = k

5/3 = k

find q when p=345 and r =9

p=k* q r

345 = (5/3) * q *9

345 = 45 q / 3

1035 = 45 q

q=23

The required value of the q in the proportionality relationship is given as q = 23.

Given that,

p varies jointly as q and r, and p = 150 when q = 18 and r = 5, find q when p = 345 and r = 9.​

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

P varies jointly as q and r

p =k × q r  - - - - - (1)

150 =k × 18× 5

k = 5 / 3

Put k = 5/3, p = 345 and r = 9 in equation 1

345 = (5/3) × q ×9

q = 23

The required value of the q in the proportionality relationship is given as q = 23.
