SOH CAH TOA <= ask me about this if you don't get it
Cos(x) = Adj / Hyp
we don't know the Hyp this time so solve for that
Hyp = Adj / Cos(x)
Hyp = 4 / Cos(45)
Hyp = 4 / [tex]\sqrt{2}/2[/tex]
maybe you know.. but i'll just remind you to bring the fraction up from the denominator... invert and multiply
Hyp = 4 * 2/[tex]\sqrt{2}[/tex]
Hyp = 8/ [tex]\sqrt{2}[/tex]
also we are supposed to write as a decimal rounded to the nearest 10th
Hyp = 5.66

Learning task 2
A.for this learning task,be able to supply the missing value if y varies jointly or if y varies both directly and inversely to x and z.
Step-by-step explanation:
Row 1
k=2 , Equation: y=2xzRow 2
x=10, k=2Row 3
y= 192, Equation: y= 4xzRow 4
z= 2, k= 3Row 5
x= 16/3, k= 3/4Note. The equation should be y = 3/4xz, not y = 3/4xy

Zachary places daisies and magnolias in a vase. If daisies cost x dollars, magnolias cost y dollars and a vase costs v dollars, mark all equations which represent the cost of 20 vases of 40 daisies and 80 magnolias.
Answer:
[tex]Total = 20v + 40x + 80y[/tex]
[tex]Total = 20(v + 2x + 4y)[/tex]
Step-by-step explanation:
The options were not given,en but the question can still be solved.
Given
[tex]Daises = \$ x[/tex]
[tex]Magnolias = \$ y[/tex]
[tex]Vase = \$ v[/tex]
Required
Determine the cost of 20 vases, 40 daises and 80 magnolias
If 1 vase costs $v, then
[tex]20\ vases = 20 * v[/tex]
[tex]20\ vases = 20v[/tex]
If 1 daises costs $x, then
[tex]40\ daises = 40 * x[/tex]
[tex]40\ daises = 40x[/tex]
If 1 magnolias costs $y, then
[tex]80\ magnolias = 80 * y[/tex]
[tex]80\ magnolias = 80y[/tex]
[tex]Total = 20v + 40x + 80y[/tex]
Another expression that represents the total is to factorize the expression.
[tex]Total = 20(v + 2x + 4y)[/tex]

Question 6
A machine is used to fill bags with a popular brand of trail mix. The machine is calibrated so the distribution of the weights of the bags of trail mix is normal,
with mean 240 grams and standard deviation 3 grams. Of the following, which is the least weight of a bag in the top 5 percent of the distribution?
Answer:
D. 246 grams
Step-by-step explanation:
invnorm(.95, 240, 3) is around 244 and the question is asking for the least weight of a bag in the top 95%, so the smallest number within
a. 234
b. 240
c. 243
d. 246
e. 248
is d.
The distribution of the mix follows inverse normal distribution
The least weight of a bag in the top 5% is 246 grams
The given parameters are:
[tex]\mathbf{\mu = 240}[/tex] ---- population mean
[tex]\mathbf{\sigma = 3}[/tex] ---- population standard deviation
To get the least weight of a bag in the top 5%, we make use of inverse normal distribution.
So, we have:
[tex]\mathbf{Least = invNorm(p,[\mu,\sigma])}[/tex]
Being in the top 5% means that:
p = 1 - 5%
p = 1 - 0.05
p = 0.95
So, we have:
[tex]\mathbf{Least = invNorm(0.95,240,3)}[/tex]
From the inverse normal calculator, we have
[tex]\mathbf{Least = 246}[/tex]
Hence, the least weight is 246 grams
