Answer:
y = 75
z = 43.3
Step-by-step explanation:
To find the value of y we use the trigonometric identity Sine.
[tex]sin\ 30 = \frac{y}{150}\\\\y=150*sin30\\y= 75\\[/tex]
Now to find the value of z we can use the trigonometric identity Tangent.
[tex]tan\ 60=\frac{y}{z}\\\\z=\frac{y}{tan\ 60}[/tex]
We know the value of y is 75 so it becomes,
[tex]z=\frac{75}{1.732} \\\\z=43.3[/tex]
Answer:
y=-150 ' z = - 468
Step-by-step explanation:
Sin angle = opp/hyp
Cos 30 = y/150
y = 150 ×( cos30)
y= - 150
Tan angles = opp / adj
Tan 60 = - 150 / Z
Z = (-150) / tan 60
Z = (-150) / 0.32
Z= - 468

Given that:

[tex]xln(x) *dx= (y+y \sqrt{(8+y^2}) \ dy[/tex]

Step-by-step explanation:
Given
The attached graph
[tex]Scale\ Factor = 1\frac{1}{2}[/tex]
Required
Determine the coordinates of F'G'H'
First, we need to get the coordinate of F, G and H from the graph
[tex]F = (-2,-2)[/tex]
[tex]G = (-2,2)[/tex]
[tex]H = (4,-2)[/tex]
The dilated coordinate is then calculated as:
[tex](FGH)' = (FGH) * Scale\ Factor[/tex]
This gives:
[tex]F' = (-2,-2) * 1\frac{1}{2}[/tex]
[tex]F' = (-2* 1\frac{1}{2},-2* 1\frac{1}{2})[/tex]
[tex]F' = (-3,-3)[/tex]

How many pavers are needed to cover the patio?
Answers
Answer:
270
Step-by-step explanation:
✔️Area of the Patio = bh
b = 12 ft = 144 in.
h = 10 ft = 120 in.
Area of Patio = 144*120 = 17,280 in.²
✔️Area of Brick Paver = bh
b = 8 in
h = 8 in
Area of the Brick Paver = 8*8 = 64 in.²
The number of quaver needed to cover the Patio = area of Patio ÷ area of one brick quaver

Answers
Answer:
8 thats how many pies and cakes you can do
Step-by-step explanation:
you have 20 minutes and 10 and the most cakes you can get with left over is 8
The pies and cakes should be made to maximize profits is 8 pies.
What is profit?Profit is defined as the sum of revenue and income after all costs have been deducted by a business. A function with a business-oriented focus is called a profit function. The main goal of a business is to generate income through the sale of goods and services, minus the costs associated with producing those goods and services, in order to turn a profit.
Revenue minus costs equals profit.
Costs comprise both variable costs and fixed costs, whereas revenue is the total amount of positive cash flow that a business generates.
The maximum number of cakes you can get with leftovers in 20 minutes and 10 is 8.
Thus, the pies and cakes should be made to maximize profits is 8 pies.

In 1923, a certain country underwent one of the worst periods in history of hyperinflation, which is extraordinarily large inflation in prices. At the peak of the hyperinflation, prices rose 11,000% per month. At this rate, by what percentage would prices have risen in 1 year? In 1 day? (Assume 30 days per month.)
The annual inflation rate is ___ x 10 ^ ___%
(Type whole numbers.)
The daily inflation rate is ___ %.
(Round to the nearest whole number as needed.)
Answers
Answer: 3.498 * 10^26 % ; 16.9% per day
Step-by-step explanation:
Inflation rate = 11,000 per month
Hence, price after a month :
Final price = initial price (1 + rate)
Final price = 1 + 11000/100
Final price = (1 + 110) * initial price
Final price = 111 times the initial price
Hence inflation over the 12 month period :
(111)^12 = 3.498 * 10^24
(3.498 * 10^24) * 100% = 3.498 * 10^26 %
The daily inflation rate :
Number of days = 30
30th root of 3.498 * 10^24 = 1.169
(1.169 - 1) = 0.169
0.169 * 100% = 16.9% per day
