ABC is a straight line.

Akimi4 [234]

Answer:

Step-by-step explanation:

What is known....AC=75 AB=4 times BC AB+BC=AC

4(BC)+BC=75 Add like numbers

4(BC)+BC=5BC

5(BC)=75 get the variable(BC) alone by dividing both sides by the number(5)

5(BC)/5=75/5 Then simplify....5(BC)/5=(BC) and 75/7=15

(BC)=15

If tan 0=11/60, what is the value of cot 0?

Alona [7]

Answer:

Step-by-step explanation:

tan 0 = 1/ cot 0

so, tan 0=11/60,

cot 0= 1/ (11/60)

Jude says that the volume of a square pyramid with base edges of 7 in and a height of 7 in is equal to the volume of a cylinder

irakobra [83]

Answer:

Jude is not correct

Step-by-step explanation:

The volume of a square pyramid is given as:

$V = a^2\frac{h}{3}$

where a = base edge and h = height

Hence, the volume of the square pyramid with base edge of 7 in and height of 7 in is:

$V = 7^2*\frac{7}{3}$

V = $114.3 in^3$ ≅ $114 in^3$

The volume of a cylinder is given as:

$V = \pi r^2h$

where r = radius and h = height

Hence, the volume of a cylinder with radius of 7 in and height of 7 in is:

$V = \pi *7^2*7$

V = $1077.57 in^3$ ≅ $1078 in^3$

Since their volumes are not equal, Jude is not correct.

I need help from MATH 9 - Linear Relation 1: The slope and the y-intercept Form <img src="https://tex.z-dn.net/?f=y%3Dmx%2Bb%3A"

SashulF [63]

Answer:i think it is y-y1=m(x-x1)

m is herein undefined.

Slope, m, is defined as change-of-y divided by change-of-x...

m=(y-y1)/(x-x1)

The mathematical concept of undefined means that the denominator is zero. This means that both values of x are equal.

(-4,-8)

This equation is x=-4

It is a vertical line and includes the point of y=-8.
