Answer:

(D). 1

Step-by-step explanation:

-17(x - 2) = 16 + x

-17 × x - (-17) × (2) = 16 + x

-17x + 34 = 16 + x

-17x - x = 16 - 34

-18x = - 18

18x = 18

x = 18/18

x = 1

Thus, The value of x is 1

Step-by-step explanation:

For sqrt(x - 4) to be defined, x >= 4.

For a(x) >= 4, 3x + 1 >= 4, x >= 1.

Hence the domain of the composite function is the 3rd from the top.

Answer:

-3v + 24

Step-by-step explanation:

-3(v - 8)

-3v + 24

you cannot simplify this expression any further

Answer:

v = [tex]-\frac{32}{3}[/tex]

Step-by-step explanation:

7v = 4v - 32

7v - 4v = -32

3v = -32

v = [tex]-\frac{32}{3}[/tex]

Answer:

10.68

Step-by-step explanation:

7v=4v-32

-4v  -4v

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

3v=-32

v=10.67

So then you'd plug that into the thing:

7(10.67)=4(10.67)-32

74.69=42.68-32

b) b=32

Step-by-step explanation:

      t=98

b) 2k/5=b/2-12

Answer: 2

Step-by-step explanation:

Step-by-step explanation:

Square root of 25 can be +5 or -5

Square root of 16 can be +4 or -4.

As -5 can be square root of 25 and +4 can be a root of 16 , -5 < +4 . That's why square root of 25 could be less than square root of 16.

Answer:

(a) The area of the triangle is approximately 39.0223 cm²

(b) ∠SQR is approximately 55.582°

Step-by-step explanation:

(a) By sin rule, we have;

SQ/(sin(∠SPQ)) = PQ/(sin(∠PSQ)), which gives;

5.4/(sin(52°)) = 6.8/(sin(∠PSQ))

∴ (sin(∠PSQ)) = (6.8/5.4) × (sin(52°)) ≈ 0.9923

∠PSQ = sin⁻¹(0.9923) ≈ 82.88976°

Similarly, we have;

5.4/(sin(52°)) = SP/(sin(180 - 52 - 82.88976))

Where, 180 - 52 - 82.88976 = ∠PQS = 45.11024

SP = 5.4/(sin(52°))×(sin(180 - 52 - 82.88976)) ≈ 4.8549

Given that RS : SP = 2 : 1, we have;

RS = 2 × SP = 2 × 4.8549 ≈ 9.7098

We have by cosine rule, [tex]\overline {RQ}[/tex]² =  [tex]\overline {SQ}[/tex]² +  [tex]\overline {SR}[/tex]² - 2 × [tex]\overline {SQ}[/tex] × [tex]\overline {SR}[/tex] × cos(∠QSR)

∠QSR and ∠PSQ are supplementary angles, therefore;

∠QSR = 180° - ∠PSQ = 180° - 82.88976° = 97.11024°

∠QSR = 97.11024°

Therefore;

[tex]\overline {RQ}[/tex]² =  5.4² +  9.7098² - 2 ×  5.4×9.7098× cos(97.11024)

[tex]\overline {RQ}[/tex]² ≈ 136.42

[tex]\overline {RQ}[/tex] = √(136.42) ≈ 11.6799

The area of the triangle = 1/2 ×[tex]\overline {PQ}[/tex] × [tex]\overline {PR}[/tex] × sin(∠SPQ)

By substituting the values, we have;

1/2 ×[tex]\overline {PQ}[/tex] × [tex]\overline {PR}[/tex] × sin(∠SPQ)

1/2 × 6.8 × (4.8549 + 9.7098) × sin(52°) ≈ 39.0223 cm²

The area of the triangle ≈ 39.0223 cm²

(b) By sin rule, we have;

[tex]\overline {RS}[/tex]/(sin(∠SQR)) = [tex]\overline {RQ}[/tex]/(sin(∠QSR))

By substituting, we have;

9.7098/(sin(∠SQR)) = 11.6799/(sin(97.11024))

sin(∠SQR) = 9.7098/(11.6799/(sin(97.11024))) ≈ 0.82493

∠SQR = sin⁻¹(0.82493) ≈ 55.582°.

Answer:

8 miles

Step-by-step explanation:

Britney went from -4 to 6, or 10 miles, and then from 10 to -14, or 24 miles. Add these together and Britney traveled 34 miles

Alice went straight from the library to school, so we need to find the hypotenuse of the triangle. Use the Pythagorean theorem (a^2 + b^2 = c^2) and substitute 10 for a and 24 for b to get 100 + 576 = c^2 or 676 = c^2

Take the square root of 676 to get 26 for Alice's distance.

Answer:

2 3/8

Step-by-step explanation:

Answer:

Assuming you meant 19/8, the answer would be 2 and 3/8

Step-by-step explanation:

How many times does 8 go into 19? Twice, plus you will have 3 leftover since 8 x 2 is only 16 and not 19. That 2 stays a 2 and the left over 3 is 3/8, so your answer is 2 + 3/8

Answer: Lol its A

Step-by-step explanation:

Answer:

It's the first one.

Answer:

Option D

Step-by-step explanation:

We have to find the value of the composite function (h o k)(2).

Since, (h o k)(x) = h[k(x)]

(h o k)(2) = h[k(2)]

From the picture attached,

At x = 2

k(2) = (-2)

Therefore, h[k(2)] = h(-2)

Since, h(x) = [tex]\frac{3}{x+1}[/tex]

Therefore, h(-2) = [tex]\frac{3}{-2+1}[/tex]

                          = -3

(h o k)(2) = -3 is the answer.

Option (D) is the correct option.
