Answer:

-4 + -2 = -6

Step-by-step explanation:

So this is a rhyme that helps me remember how to add and subtract positive and negative numbers...

<em />

<em>(To the tune of Row Row Row Your Boat)</em>

Same sign add and keep

Different sign subtract

Keep the sign of the bigger number

Then you'll be exact

spin [16.1K]
Since Ryan is 5 feet tall, we will assume that the height of the cell-phone tower is x + 5.
Since the given is 54 degrees. 
Tan 54degrees = x/80(feet)
x=80(tan54)
x=110
To finalize the answer, we will add up the height of the cell-phone tower to the answer. 
110 + 5 = 115 feet
So the answer to the question is that the height of the cell-phone tower is 115 ft.

Consider a 25 factorial design. (a) How many factors and levels are considered in this factorial experiment
Bad White [126]

Answer:

Step-by-step explanation:

From the information given;

We are to take a look at a 2⁵ factorial design.

The factorial design consists of carrying out the design of equipment by testing it by modifying not the parameters one by one but by modifying several simultaneous parameters.

An experiment is termed to be a 2⁵ factorial experiment if in the experiment 5 factors are studied consecutively with each at two-level.

Thus, there are five factors and 2 levels in the experiment.

Question 6 (1 point) (01.03 LC) What is the value of 5 to the power of 4 over 5 to the power of 6? (1 point) a 1 over 25 b 1 ove
Vlad [161]

Answer:

a 1 over 25

Step-by-step explanation:

Problem Statement:

     What is the value of  \frac{5^{4} }{5 ^{6} } ?

To solve this problem, we must familiarize ourselves with the concept of exponents and rules that guides them.

Exponents are used by scientists to report higher orders of a number.

Such large and often recurring expression is usually made up of a base and an exponent value.

The exponent value is the power of the base;   for example, 4³ has 4 as its base and 3 as the exponent.

Several rules guides solving an exponent, to this problem, the most applicable one is :

                            \frac{x^{a} }{x^{b} }  =  x^{(a-b)}

                           \frac{5^{4} }{5 ^{6} }   =  5^{4-6}  

                                 = 5^{-2}

                                 = \frac{1}{25}                                  

Therefore the solution is 1 over 25
