Answer:
f(x)= 1.38x
y= 1.38x
Step-by-step explanation:
basically the cost= 1.38 per pound
you can use cost=1.38x if ur grade level isn't at f(x) yet
<3
Answer:
f(x) = 1.38x
x just stands for a number so depending on how many pounds you get you would times the pounds by 1.38. And f(x) (pronounced "f of x") means that each input has a single output. So if you bought 2 pounds of strawberries, the equation would change to this:
f(2) = 1.38(2)
The x's were just replaced with 2's, see? I wish someone had explained this to me earlier lol

A bag of Jolly Ranchers contains 300 pieces of which 28% are blue. How many are not blue?
Answer:
216
Step-by-step explanation:
300 x .28 = 84
300 - 84 = 216
Answer:
216
Step-by-step explanation:
300 -> 100% (Total candies)
___ -> 72% (NOT Blue candies)
___ -> 28% (Blue candies)
Next:
28% = 0.28
300 x 0.28 = 84
84 = Number of candies that are Blue
300 -> 100% (Total candies)
___ -> 72% (NOT Blue candies)
84 -> 28% (Blue candies)
Now:
300 - 84 = 216
300 -> 100% (Total candies)
216 -> 72% (NOT Blue candies)
84 -> 28% (blue candies)
216 equals the number of candies that are NOT Blue

I need the endear for number six. Will give brainliest for help/answer.
Answer:
f(1) = 2, f(4) = 8
Step-by-step explanation:
f(1) in the interval - 3 < x ≤ 1 , then f(x) = x + 1 , so
f(1) = 1 + 1 = 2
f(4) in the interval 1 < x ≤ 4 , then f(x) = 2x , so
f(4) = 2 × 4 = 8

Solve for the perimeter of the figure below. Round your answer to the nearest hundredth. Show your work and explain the steps
you used to solve.
Answer:
18.87 units
Explanation:
the estimated distance from a to d is the same as a to b. we can find the length of the diagonal using pythagoras' theorem:
a² + b² = c²
√(2² + 3²) = 3.6056 (to 5s.f.)
now, we can use the same method to calculate the distance between d and c, as well as c and b:
√(3² + 5²) = 5.8310 (to 5s.f.)
adding these values, we will get:
(3.6056 + 5.8310) × 2 = 18.87 units (to the nearest hundredth)
i hope this helps! :D

A camper on top of a 400 foot cliff is enjoying the view. They look down and see a
bear at an angle 37 degrees. Approximately how far is the bear from the base of the
cliff? (Round your answer to the nearest foot.). REMEMBER THE UNITS
Answer:
301.42 ft from base
Step-by-step explanation:
We can look at this situation as a triangle, the cliff is straight up and we're looking for the lowest side of the triangle. So to figure this out we use tangent, tangent is equal to Opposite over adjacent. So the tangent(37)= bear from base/height of cliff. We then multiply tan(37) by 400 to get the answer

how to verify the identity?
Answer:

Step-by-step explanation:
Using the identities
sin(A + B) = sinAcosB + cosAsinB
cotA = [tex]\frac{cosA}{sinA}[/tex] , tanA = [tex]\frac{sinA}{cosA}[/tex]
Consider the left side
[tex]\frac{sin(A+B)}{sinAcosB}[/tex]
= [tex]\frac{sinAcosB+cosAsinB}{sinAcosB}[/tex]
= [tex]\frac{sinAcosB}{sinAcosB}[/tex] + [tex]\frac{cosAsinB}{sinAcosB}[/tex]

Answer:
1. a. Q° = 95°
b. a = 20.3; b = 19.3
2. p = 36; q = 14.4
Step-by-step explanation:
Question 1:
Recall: The Exterior Angle Theorem of a Triangle states that the size of the exterior angle of a triangle equals the sum of the two sizes of the two opposite angles of the triangle.
a. Based on the theorem,
Q° = 41° + 54° = 95°
b.
✔️122° = 4a + 2a (exterior angle theorem)
122 = 6a
Divide both sides by 6
122/6 = a
a = 20.3
✔️122° + 3b = 180° (angles on a straight line)
3b = 180 - 122
3b = 58
b = 58/3
b = 19.3
Question 2:
Recall: Opposite angles of a parallelogram are equal while adjacent/consecutive angles are supplementary.
✔️2p + 3p = 180° (adjacent angles)
5p = 180
p = 180/5
p = 36
✔️2p = 5q (opposite angles)
Plug in the value of p
2(36) = 5q
72 = 5q
72/5 = q
q = 14.4

Please help! I do not know how to find the unknown variables using the Pythagorean theorem. Any help will be greatly appreciated:))
Answer:
Angle Z = 180-32 -90 = 58 degrees
sine (32) = y / 16
y = 16 * sine (32)
y = 16 * 0.52992
y = 8.47872
x^2 = 16^2 -y^2
x^2 = 256 -71.888
x^2 = 184.112
x = 13.568
Step-by-step explanation:
Answer:
x = 13·568, y = 8·47 and z = 58
Step-by-step explanation:
I don't think the question required you to use the Pythagoras theorem but here are some pointers anyway.
Okay, the Pythagoras theorem is quite simple: a² + b² = c²Where c is always the hypotenuse, a is the height or the opposite side and b is the base or the adjacent side. (I've attached a picture just in case) (It might look confusing but the way I've lettered them is taking the 90° angle to be on the right side)The a and b doesn't actually matter so don't think too much about which side is a and which one is b, they're more or less the same.The reason I said that this question might not solely require you to use the Pythagoras theorem is because you need to have two variables for the equation to work, maybe this is what got you confused.
For this question, you're required to use Tangents, Sines and Cosines, or you can combine this method and Pythagoras method.
Looking for x and y:Method one: Using Tangents, Sines and Cosines AND the Pythagoras theorem
Step 1: Looking for x(Using Sin, Cos and Tan)
To find the length of side x, we need to use the Cosine of 32°
Cos 32° = Adjacent side ÷ Hypotenuse
0·8480 = x/16
Make x the subject and multiply both sides by 16
0·8480 × 16 = x/16 × 16
13·568 = x
∴ side x is 13·568
Step 2: Looking for y( using the Pythagoras theorem)
a² + b² = c²
a = y, b = x = 13·568, c = 16
y² + 13·568² = 16²
y² + 184·0906 = 256
y² = 256 - 184·0906
y² = 71·9094
y = √71·9094
y = 8·4799
Method 2: Using Tan, Cos and Sin only
Step 1 remains the same as shown above; x = 13·568
Step 2: Looking for y
Y can be gotten by using the Sine of 32°
Sin 32° = Opposite ÷ Hypotenuse
Sin 32° = y ÷ 16
0·5299 = y/16
Make y the subject and divide both sides by 16
0·5299 × 16 = y/16 × 16
8·4784 = y
∴ y is equal to 8·4784
(I know there's a difference in points of the two values of y, but if you round them off to 2 decimal places we see it remains 8·47
2. Looking for z:
Using addition and subtraction
The simpler method would be to just add all the internal angles.
The little square in the corner tells us that that is a 90° angleThe internal angles of a triangle ALWAYS add up to 18032 + 90 + z = 180
122 + z = 180
z = 180 - 122
z = 58
∴ z is equal to 58°
Using Tan, Sin and Cos
The cosine of Z is equal to y divided by 16, where y = 8·47
Cos z = 0·5294
Make z the subject and divide both sides by Cos.
z = 0·5294/Cos
z = 58·04° (I just used the anti-cos to get this number. Press shift, and cos on your calculator then type 0.5294 in front of it)
Here there is also a slight difference in points between the two steps but if you round off step 2 to a whole number you get 58, so it's all good :)
HOPE THIS HELPS!!! :)
