7 + 34.5x = 8 1/4
find the value for x
and please hurry

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

Answer: 360 apples were taken

Step-by-step explanation:

Here, we are asked to find the number of apples taken, which means it is the difference between original and after. So the expression we are going to use is: Original-After=number of apples taken

------------------------------------------------------------------------------------

Given

Original=409 apples

After=49 apples

Solve

Original - After=409 - 49=360 apples

Hope this helps!! :)

Answer/Step-by-step explanation:

Recall: SOHCAHTOA

2. Reference angle = 62°

Adjacent = 25

Opposite = x

Apply TOA:

Tan 62 = Opp/Adj

Tan 62 = x/25

25*Tan 62 = x

x ≈ 47.0 (nearest tenth)

3. Reference angle = 26°

Hypotenuse = x

Opposite = 11

Apply SOH:

Sin 26 = Opp/Hyp

Sin 26 = 11/x

x × Sin 26 = 11

x = 11/Sin 26

x ≈ 25.1 (nearest tenth)

4. Reference angle = 48°

Hypotenuse = 32

Opposite = x

Apply SOH:

Sin 48 = Opp/Hyp

Sin 48 = x/32

32 × Sin 48 = x

x ≈ 23.8 (nearest tenth)

5. Reference angle = 12°

Hypotenuse = x

Adjacent = 29

Apply CAH:

Cos 12 = Adj/Hyp

Cos 12 = x/29

29 × Cos 12 = x

x ≈ 28.4 (nearest tenth)

6. Reference angle = x

Hypotenuse = 15

Adjacent = 14

Apply CAH:

Cos x = Adj/Hyp

Cos x = 14/15

x = cos^{-1}(14/15)

x ≈ 21.0° (nearest tenth)

7. Reference angle = x

Opposite = 19

Adjacent = 23

Apply TOA:

Tan x = Opp/Adj

Tan x = 19/23

x = Tan^{-1}(19/23)

x ≈ 39.6° (nearest tenth)

8. Reference angle = x

Hypotenuse = 17

Adjacent = 9

Apply CAH:

Cos x = Adj/Hyp

Cos x = 9/17

x = Cos^{-1}(9/17)

x ≈ 58.0° (nearest tenth)

9. Reference angle = x

Hypotenuse = 45

Opposite = 43

Apply SOH:

Sin x = Opp/Hyp

Sin x = 43/45

x = Sin^{-1}(43/45)

x ≈ 72.9° (nearest tenth)

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

Answer:

A polynomial function can be factored by its roots

f(x) = (x-a).(x-b). ... (x-r)

Which a, b, ... r are roots

In this case

f(x) = (x+12).(x-7)

But

f(x) = (x-(-12)).(x-7)

Thus roots are

-12 and 7

Distance is the abs function

abs(-12,7) = |-12 - 7| = 19

Ans: 19

The answer is G

Step-by-step explanation:

So what I did was I went on a website that it wont let me name and typed in each equation and then the ordered pair and checked to see if (8,-1) was a solution and it was for G.

Answer:

see explanation

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]

= 1 + [tex]\frac{cosA}{sinA}[/tex] . [tex]\frac{sinB}{cosB}[/tex]

= 1 + cotA tanB = right side , thus verified

Answer:

B. slope = Undefined, x = 3

Step-by-step explanation:

The equation of a vertical line always takes the form x = k, where k is any number and k is also the x-intercept .

So the slope for this is undefined, since it's just a vertical line so, since the equation is x = k. If it's horizontal then it's 0.

the best fit for this is the first option slope = undefined, x = 3.

slope: Undefined

x-intercept: 3

Answer:

Its undefined

Step-by-step explanation:

Vertical is undefined

Horizontal is Zero

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

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

Answer:
