Zarea finds 3^√6000 and shows her work below. 3^√6000 = 3^√? x 3^√6 = 10 ^3√6 what is the missing value?

Answers

Answer:

? = 1000

Step-by-step explanation:

Zarea is making use of the fact that the cube root of a product is the product of the cube roots. She is factoring out the largest perfect cube in the number 6000.

[tex]\displaystyle \sqrt[3]{6000}=\sqrt[3]{1000\cdot6}=\sqrt[3]{\boxed{1000}}\cdot\sqrt[3]{6}=10\sqrt[3]{6}[/tex]

OAB is a triangle
OA = 4a and OB = 5b
M is the midpoint of OB
AN:NB = 2:3
Find OP:PN

Answers

Answer:

5:2

Step-by-step explanation:

ON = OA + AN

AN = 2/5AB

AB = 5b-4a

AN = 2b - 8/5a

ON = 4a - 8/5a +2b

ON = 12/5a+2b

OP = k(12/5a+2b)

OP = OA + AP

AP = x(AM)

AM = 5/2b-4a

OP=4a-4ax+5/2bx

OP=4a-4ax+5/2bx and OP=12/5ak+2bk

Coefficients of A

4-4x=12/5k

k=(20-20x)/12

Coefficients of B

5/2x=2k

k=5/4x

(20-20x)/12 =5/4x

20=35x

x=4/7

k=5/4 * 4/7 = 5/7

OP=k(ON)

OP = 5/7

PN = 2/7

OP:PN = 5:2

Give the equation the circle (X+5)^2+(y-1)^2=16, which correctly gives the center and radius of the circle

Answers

Answer:

Step-by-step explanation:

You have:

[tex](x+5)^2+(y-1)^2=16[/tex]

[tex](x+5)^2+(y-1)^2=4^2[/tex]

To find the center of the circle, you want to find the 'x' and 'y' values which make their respective term equal zero:

[tex](x+5)^2=0[/tex]

[tex](y-1)^2=0[/tex]

[tex]x=-5[/tex]

[tex]y=1[/tex]

The radius of the circle would be 4 due to the right side of the circle equation. Our circle is centered at (-5, 1) and has a radius of 4 units.

If a student wants to multiply by 8 they can?

A. Multiply by 2 three times
B Multiply by 2 four times
C Multiply by 4 twice
D Multiply 2 and multiply by 4 and add them together

Answers

The answer is A because 2^3 or 2x2x2=8. So if you multiply a number by 2 three times it would be the same as multiplying a number by 8.

Hello Brainly user,

A. Multiply by 2 three times if you want to multiply by 8.

Proof:

For example, if you want to multiply 2 by 8 --> 2x8 then you can just do 2x2 = 4 4x2 = 8 8x2 = 16.

TO CHECK:

You can do 8x2 = 16.

Hence, this answer is 100% correct.

What is Triangle?

A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

We have,

The measure of three sides are 6 ,6 and 6.

Now, we know a triangle whose three sides are equal is called as Equilateral Triangle.

Also, three angles are Equal.

Using Angle Sum property

x + x + x = 180

3x= 180

x= 60

Thus, the measure of three angles are 60, 60 and 60.

Step-by-step explanation:

First: split the figure into 2:

(5 * 9 * 2)*(5 * 4)

Then, solve the first:

5 * 9 * 2= (5 * 9) * 2= 45 * 2= 90

Next, solve the second part:

5 * 4= 20

Finally, multiply both parts:

90 * 20= 1800.

Step-by-step explanation:

subtract sin(x) from both sides:

[tex]\implies \sin(x)=\dfrac12[/tex]

[tex]\implies x=\dfrac{\pi}{6} \pm2 \pi n, \dfrac{5\pi}{6} \pm2 \pi n[/tex]

39. Algebra A rectangle has a base of x units. The area is (4x2-2x)
square units. What is the height of the rectangle in terms of x?
A (4 - x) units
(x-2) units
B (4x3 - 2x2) units
D (4x - 2) units
-
-

Answers

The area of the rectangle is the product of its base and height

The height of the rectangle is 4x - 2 units

How to determine the height?

The given parameters are:

Area = 4x^2 - 2x

Base = x

The area of the rectangle is:

Area = Base * Height

This gives

4x^2 - 2x = x * Height

Divide through by x

4x - 2 = Height

Rewrite as:

Height = 4x - 2

Hence, the height of the rectangle is 4x - 2 units
