Explanation:
Obviously, the way you use trig ratios will depend on the problem. The problems you see in algebra and trig courses are a good sampling of the kinds of problems you run across in the real world. Some of them include ...
finding height or widths based on a measure and an angle (SOH CAH TOA)
finding areas based on side lengths and an angle (area formula)
finding unknown sides or angles of a triangle (law of sines/cosines)
finding bearing and/or distance (spherical trig relations, law of cosines)
__
As with solving problems of any kind, you choose the appropriate formula(s), fill in the known values, and solve for the unknown values. Sometimes a real-world problem will require solution of intermediate problems before the answer to the original question is found.

The cookie recipe called for oatmeal and raisins in the ratio of 3 to 1. If 4 cups of oatmeal were called for, how many cups of raisins were needed?
Answer:
1.33 or about 2
Step-by-step explanation:
Answer:
12 cups of raisins
Step-by-step explanation:
If our ratio is 3 to 1 or for every one cup of oatmeal we have 3 cups of raisins, we want our new ratio to be equal to that ratio!
Our new ratio is ? to 4, we know that for every one cup of oatmeal we have 3 cups of raisins then...
We have to multiple 3×4 to find our ?
3×4 = 12
So, we know that for every 4 cups of oatmeal we will have 3 cups of raisins!
Hope this Helps! :)

What is the image of (-10,-6) after dilation by a scale factor of 1/2 centered at the origin?
The coordinate of resulting image after dilation is (-5, -3)
Dilation and scale factorsGiven the coordinate of an image (-10,-6), dilating the coordinate by 1/2 means reducing the image by multiplying each coordinate by the factor of 1/2.
Image = (1/2(-10), 1/2(-6))Image = (-5, -3)From the calculation above, you can see that the coordinate of resulting image after dilation is (-5, -3)

Answer:
[tex]y = 6(2^{x} )[/tex]
Step-by-step explanation:
Let
[tex]y = kb^{x}[/tex]
When x = 0, y = 6. So, [tex]6 = kb^{0}[/tex] = k(1 ) = k
Since k = 6 we have [tex]y = 6b^{x}[/tex]
When x = 1, y = 12.
So [tex]12 = 6b^{1} = 6b[/tex]
b = 2
Therefore, the exponential function is [tex]y = 6(2^{x} )[/tex]
What is the range of the function f(x)= 2 + 4 when the domain is {-2, 0, 3}?
A {4.25, 5, 12}
B. {0, 4, 10}
C. {4.25, 4, 12}
D. All Real Numbers
The domain is the possible input values "x" .. in this case [-4, -2, 0, 2, 4]
The range are the possible output values of f(x)
We need to solve f(x) = 3.2x for each value in our domain
f(-4) = 3.2(-4) = -12.8
f(-2) = 3.2(-2) = -6.4
f(0) = 3.2(0) = 0
f(2) = 3.2(2) = 6.4
f(4) = 3.2(4) = 12.8

-360 divided by -40 ?
Answer: 9
Step-by-step explanation:
The required -360 divided by -40 is equal to 9. The negative signs cancel out when dividing two negative numbers, resulting in a positive result.
When dividing two negative numbers, it's helpful to keep in mind the following rule:
The division of two negatives yields a positive result.
Now, let's perform the division:
-360 ÷ -40
Since both numbers are negative, we know the result will be positive.
Divide the absolute values of the numbers.
|-360| ÷ |-40| = 360 ÷ 40 = 9
Apply the rule for the division of two negatives.
Since both numbers are negative, the result will be positive:
-360 ÷ -40 = 9
Therefore, -360 divided by -40 is equal to 9.

hey just tell me is it a right angled triangle or not?
Help please!!! Find x and Y
Answer:
x = 40
y = 15
Step-by-step explanation:
Given is an equilateral triangle.
Measure of each angle of an equilateral triangle is 60°.
Therefore,
(x + 20)° = 60°
x + 20 = 60
x = 60 - 20
x = 40
4y = 60
y = 60/4
y = 15

poop kdfkdkddkejdfjdidjs didneidndzusnxixdn
1 1/2 hours
Time spent by Antonio in driving = 3 1/4 = 13/4
Time spent in gardening = 1 3/4 = 7/4
In order to find how much he spend driving than gardening, we can subtract 13/4 and 7/4.
13/4 - 7/4
Te denominator is same. So, we can directly subtract the numerators.
13-7/4
=6/4
= 3/2 = 1 1/2
Therefore, Antonio spent 1 1/2 hours more in driving than gardening.

How many solutions does the system have? { y = − 7 x + 8 y = − 7 x − 8 ⎩ ⎪ ⎪ ⎨ ⎪ ⎪ ⎧ y=−7x+8 y=−7x−8
The system of equations y =−7x + 8 and y = −7x − 8 have no solution
How many solutions does the system have?From the question, we have the following parameters that can be used in our computation:
y =−7x + 8
y = −7x − 8
Subtracting the two equations
We have
y - y = -7x + 7x + 8 + 8
When the like terms are evaluated, we have
0 = 16
The above equation is false
This means that the equation has no solution

The explicit formula for the geometric progression is f ( x ) = 3 ( 4 )ˣ⁻¹
What is Geometric Progression?A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.
The nth term of a GP is aₙ = arⁿ⁻¹
The general form of a GP is a, ar, ar2, ar3 and so on
Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )
Given data ,
Let the geometric progression be represented as A
Now , the value of A is
f ( x + 1 ) = 4 f ( x )
where the second term is a₂ = 12
Now , the explicit formula is given by
f ( x ) = 3 ( 4 )ˣ⁻¹
when x = 2
f ( 2 ) = 3 ( 4 )²⁻¹
f ( 2 ) = 3 ( 4 )
f ( 2 ) = 12
Hence , the GP is f ( x ) = 3 ( 4 )ˣ⁻¹
