Answer:

5.8

Step-by-step explanation:

To find x use SohCahToa (sin, cos, tan). In this case, we are given the adjacent, and we are looking for the opposite of the angle. This means that tangent should be used. The equation should be set up as $tan(58)=\frac{x}{3.6}$ . Then, to isolate the variable multiply both sides by 3.6. This means that the new equation 3.6tan(58)=x. Finally, plug this into a calculator to solve. The final answer is 5.8.

What is the sum of the first 75 even numbers starting with 2? Enter your answer in the box.

vova2212 [387]

Answer:

5700

Step-by-step explanation:

step 1 Address the formula, input parameters & values.

Input parameters & values:

The number series 2, 4, 6, 8, 10, 12, . . . . , 150.

The first term a = 2

The common difference d = 2

Total number of terms n = 75

step 2 apply the input parameter values in the AP formula

Sum = n/2 x (a + Tn)

= 75/2 x (2 + 150)

= (75 x 152)/ 2

= 11400/2

2 + 4 + 6 + 8 + 10 + 12 + . . . . + 150 = 5700

Therefore, 5700 is the sum of first 75 even numbers.

A technical machinist is asked to build a cubical steel tank that will hold of water. Calculate in meters the smallest possible

Charra [1.4K]

Answer:

The smallest possible length is 0.83m

Step-by-step explanation:

Given

$Volume = 565L$

Required

The smallest length of the tank

Since the tank is cubical, then the volume is:

$Volume = Length^3$

This gives:

$565L= Length^3$

Express as $m^3$

$\frac{565m^3}{1000} = Length^3$

$0.565m^3 = Length^3$

Take cube roots of both sides

$0.8267m = Length$

Rewrite as:

$Length = 0.8267m$

Approximate

$Length = 0.83m$
