Answer:

C) ¼ ∫ u⁵ du, where u = sin(4x)

Step-by-step explanation:

∫ cos(4x) sin⁵(4x) dx

Using u substitution:

u = sin(4x)

du = 4 cos(4x) dx

¼ du = cos(4x) dx

¼ ∫ u⁵ du

An 11-inch string is cut into 3 equal pieces. Which expression shows the length of each piece?
slega [8]
Sense this string would only be 11 (in), and we are cutting it into 3 pieces, this would show us that we would then be dividing the 11 (in) string into 3 pieces. The expression would be below.

Cube-shaped blocks are packed into a cube-shaped storage container. The edge of the storage container is 2 1/2 feet. The edge le
GarryVolchara [31]

Answer:

Volume of one cube shaped block is, 0.125 cubic feet

Step-by-step explanation:

Volume of a cube(V) is given by:

V = a^3                 .....[1]

where a is the edge length of the cube.

As per the statement:

Cube-shaped blocks are packed into a cube-shaped storage container. The edge of the storage container is 2 1/2 feet.

⇒\text{Edge length of storage} = 2\frac{1}{2} = 2.5 ft

It is also given that:

The edge length of each block is 1/5 the edge length of the storage container

⇒\text{Edge length of each block (a)} = \frac{1}{5} \cdot 2.5 = 0.5 ft

Substitute this in [1] we have;

V = (0.5)^3 = 0.125 ft^3

Therefore,  volume, in cubic feet, of one cube-shaped block is, 0.125

Math! Who’s knows the answer?
kykrilka [37]

Answer:

M=30 degrees

because 102+148=150 and 180-150=30. (remember the sum of a triangle is 180 degrees)

the congruence statement would be SAS (side angle side) because 102 and 48 are the same in both triangles, but the third side is not the same.

What steps do you use to solve y=x+12 and y=-x+17 an unknown number y is 12 more than an u known number x the number y is also x
Tamiku [17]

Answer:

x=2.5

Step-by-step explanation:

Solve for x in this systems of equations, we already have two values which equal y so half the work is finished for us.

Starting with the equation:

x+12=17-x

Add x to both sides to remove the negative x on the right side of the equation:

2x+12=17

Subtract 12 from both sides to remove the 12 on the left side of the equation:

2x=5

Divide both sides by 2 to cancel out the x coefficient

x=2.5
