What is the GCF of 72 and 36

Answer:

36

Step-by-step explanation:

GCF or greatest common factor is the greater/biggest number that can factor for both numbers. To find GCF, you need to make factor of both number

72- 2 * 2 * 2 * 3 * 3 = 2^3 * 3^2

36= 2 * 2 * 3 * 3 = 2^2 * 3^2

After this, you can compare the factor of both numbers. Both numbers can be divided by 2, but 36 can be divided 2 times while 72 can be divided 3 times. In this case, you take the lowest number which is 2. Both numbers can be divided by 3^2 so you can take it whole.

The factor will be: 2^2 * 3 *2= 4 * 9= 36

Find the length of the curve. R(t) = 7t, 3 cos(t), 3 sin(t) , −2 ≤ t ≤ 2

Leviafan [203]

we are given

$r(t)=(7t,3cos(t),3sin(t))$

we can find x , y and z

$x=7t,y=3cos(t),z=3sin(t))$

now, we can use arc length formula

$L=\int\limits^a_b {\sqrt{(x')^2+(y')^2+(z')^2} } \, dt$

now, we can find derivative

$x'=7,y'=-3sin(t),z'=3cos(t))$

now, we can plug values

and we get

$L=\int _{-2}^2\sqrt{7^2+\left(-3\sin \left(t\right)\right)^2+\left(3\cos \left(t\right)\right)^2}dt$

$L=\int _{-2}^2\sqrt{7^2+9}dt$

$=\sqrt{58}\cdot \:2-\left(-2\sqrt{58}\right)$

$L=4\sqrt{58}$ ...........Answer

When using the substitution method for solving a system of linear equations in two variables, what should be the first step?

Yuri [45]

The first step would be to isolate a variable (solve for a variable)....so u will have something to sub into the other equation

Can someone help me with this question ASAP

sattari [20]

Let m be the slope:

m=(y₂-y₁)/(x₂-x₁)

solve for c:

1/6=(9-c)/(1-7)

1/6=(9-c)/-6

-1=9-c

-10=-c

c=10
