Answer:
1-2*sin^2 (x) = 2cos^2(x) -1
Step-by-step explanation:
1-2sin^2(x)
= 1-2(1-cos^2(x)) =2cos^2(x)-1; Pythagorean identity, sin^2(x)=1-cos^2(x)
=1-2+2cos^2(x)=2cos^2(x)-1; distribute
= -1+2cos^2(x)=2cos^2(x) -1; collect and rearrange terms
= 2cos^2(x)-1 = 2cos^2(x)-1
What is the area of this figure?
Answer:
35 cm
Step-by-step explanation:
Answer:
0.35 meters^2 or 35 cm^2
Step-by-step explanation:
we break up the shape and the problem into two parts.
we will begin by finding the area of the triangle first (or you could find the square's area first) and we know the area formula for a triangle is
Area (triangle) = (1/2) base x height
height = 0.04 meters or 4cm
base = 0.05 meters or 5 cm
therefore the area is:
(1/2) (5cm)(4cm) = 10 cm^2
now we find the area of the square which is very easy. it is simply base times the height (b x h)
Area (square) = 5cm x 5cm = 25cm^2
finally, we add the total area
Area (total) = Area (square) + Area (triangle) = 10 cm^2 + 25 cm^2
= 35 cm^2

Suppose the government sets a price floor of $4.85 per bushel of wheat when the equilibrium price is $4.55 per bushel. This price floor will:
This price floor would lead to an excess in the supply of wheat.
What is the effect of the price floor?
A price floor is when the government sets the minimum price of a product. A price floor is binding if it is set above equilibrium price.
The price floor ($4.85) is set above equilibrium price ($4.55), quantity supplied would exceed quantity demanded and there would be a surplus.

A newborn baby weighs 5 lb 4 oz. What is the weight in kg? Round to the nearest hundreth
Answer:
2.38 kg
Step-by-step explanation:
5 lbs and 4 oz = 5.25 lbs
5.25 lbs to kg = 2.38
The weight of the newborn would be 2.38 kg.
Used the concept of measurement unit that states,
A measurement unit is a standard quality used to express a physical quantity. Also, it refers to the comparison between the unknown quantity with the known quantity.
Given that,
A newborn baby weighs 5 lb 4 oz.
Since we know that,
1 oz = 0.0625 lb
Hence,
4 oz = 4 × 0.0625 lb
= 0.25 lb
So the newborn baby weighs is,
5 lb + 0.25 lb
= 5.25 lb
Since, 1 lb = 0.454 kg
Hence,
5.25 lb = 5.25 × 0.454
= 2.3835 kg
Round to the nearest hundredth,
5.25 lb = 2.38 kg

Use the t-distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from random samples, and if the sample sizes are small, assume the underlying distributions are relatively normal.
Test H0 : μ1=μ2 vs Ha : μ1≠μ2 using the sample results x⎯⎯1=15.3, s1=11.6 with n1=100 and x⎯⎯2=18.4, s2=14.3 with n2=80.
(a) Give the test statistic and the p-value.
Round your answer for the test statistic to two decimal places and your answer for the p-value to three decimal places.
The test statistics and the p-value from the research sampling will be 1.57 and 0.119.
What is test statistic?It should be noted that a test statistic simply means a number that's used to describe how the observed value is far from the null hypothesis.
In this case, the test statistics is 1.57. The p value will be:
= 2 × 0.0593
= 0.119
Therefore, the test statistics and the p-value from the research sampling will be 1.57 and 0.119.
