What is the rule for a translation of 9 units to the left and 10 units up?

1 answer:

8 0

When you move nine units to the left, you are subtracting 9 from x. When you are moving nine units up, you are adding 10 to y. So, (x, y) -> (x - 9, y + 10).

A cubic inch of PVC material weight 0.063 pounds per cubic inch. What’s the weight of a 36 inch piece of PVC pipe with an outsid

artcher [175]

Answer:

Option B. 0.783 pounds

Step-by-step explanation:

step 1

Find the area of a a 36 inch piece of PVC pipe with an outside diameter of 0.82 inches and an inside diameter of 0.75 inches

The area of a circle is equal to

$A=\pi r^{2}$

we have

$r2=0.82\ in$

$r1=0.75\ in$

assume

$\pi =3.14$

$A=\pi (r2^2-r1^2)$

substitute the values

$A=(3.14)(0.82^2-0.75^2)$

$A=0.345086\ in^2$

step 2

Find the volume of the piece of PVC

Multiply the area by its length

$V=0.345086(36)=12.42\ in^3$

step 3

Find the weight of the piece of PVC

Multiply the volume by its density

The density is $0.063\frac{lb}{in^3}$

$W=12.42(0.063)=0.783\ lb$

Which statements are true? Check all that apply. Magnitude is never a negative value. The magnitude of –1.9 is |–1.9| which is 1

AnnZ [28]

Answer:

A, B, D

Step-by-step explanation:

The options are:

A. Magnitude is never a negative value

This is true because the magnitude is only a representation of the numerical value of a number. It is the distance of the number from the 0 point on the number line. It is the absolute value of a number.

Hence, the polarity of the number is not necessary.

B. The magnitude of –1.9 is |–1.9| which is 1.9

This is true because they have the same numerical value.

C. The absolute value of a number is greater than its magnitude

This is false because absolute value and magnitude of a number are the same.

D. The numbers –4 and 4 have the same magnitude

This is true. They have the same absolute value, hence, they have the same magnitude.

E. The magnitude of -2/3 is less than the magnitude of 2/3

This is false as already explained in C above.
