3x is the GCF for these pair of monomials
Answer:
sin(x) and cos(y) are equal and have ratio of 1 : 1
First find the missing hypotenuse using Pythagoras theorem:
a² + b² = c²
12² + 5² = c²
c = √144+25
c = 13
using sine rule:


using cosine rule:


Answer:
C. 5x and x are like terms.
Step-by-step explanation:
Like terms have the same degree of the variable
5x and x are like terms because both have x to the power 1
Answer:
Yes. Fertilization increases grape yields by more than 5 pounds.
Step-by-step explanation:
Let f-fertilized and o-old(unfertilized)
#First, we use our data to calculate the standard error:

#State both null and alternative hypothesis:

#We determine our degrees of freedom as 87.02(using R), we now compute the t-value as:

Since, the p-value is low, we Reject the null hypothesis. The is enough evidence suggesting that grape yields increase by more than 5 pounds than mean yields of unfertilized grapes.
In this example, we are asked to find the perimeter of the trapezoid. The perimeter of a figure is the distance around the figure.
To find the perimeter of the trapezoid, all we have to do is add the lengths of the sides. In this case, we would add 3 + 5 + 3 + 9 = 20 cm.
<em>Therefore, the perimeter of the trapezoid is 20 cm</em>
