help help mEEEEEEEEEEEE PLEASE PLEASE

Answer:

x = 8

Steps:

(4x-2) + (17x+14) = 180

4x + 17x -2 + 14) = 180

21x + 12 = 180

21x = 180-12

21x = 168

x = 168/21

x = 8

C. Inherited traits carry the instructions for individual genes is the statement that does not describe the relationship between genes and inherited traits. Genes carry the instructions for inherited traits, not the other way around.

Answer:

The answer is B, P = 12(1.004)^t

A growth rate of 0.4% means you have to multiply by 1.004

B is the only answer with this number, so B is the correct choice.

Answer:

It's 76 degrees

Step-by-step explanation:

Thanks for branliest

Answer:

76

Step-by-step explanation:

the interior angles of a triangle always add up to 180 degrees, so all we have to do is add the 2 angle values that we know, so 48 + 56=104, then we subtract that from 180 to get 76. Hope this helps!

Answer: A) x = 1/4y^2

Step-by-step explanation:

If you graph each of the choices on a graphing calculator (I recommend Desmos!) you can see which equation could be that of the parabola shown. Sorry if this isn't the explanation you were looking for.

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

Answer:

21

Step-by-step explanation:

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.

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.

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.

32 + 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!!! :)

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:

3

Step-by-step explanation:

18+18 = 36. 42-36 = 6. 6 / 2 = 3

Answer:

s = 3

Step-by-step explanation:

2 sides measure 18 so

42- 18 - 18 = 6

2 sides  =  s

so 2s = 6

divide both sides by 2 and taaadaaa

s = 3

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:

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

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:

x=35°

y=145°

Step-by-step explanation:

y=180°-35°=145°

x=35

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
