Which expression represent the approximate length of BC HEEEEELLLLPPP!!!

Mathematics
1 answer:
Bumek [7]3 years ago
5 0

Answer:

A

Step-by-step explanation:

Using the Sine rule in Δ ABC

\frac{sinA}{BC} = \frac{sin38}{AB} , substitute values

\frac{sin66}{BC} = \frac{sin38}{3} ( cross- multiply )

BC sin38° = 3 sin66° ( divide both sides by sin38° )

BC = \frac{3sin66}{sin38} → A

BRAINLIEST PLEASE HELP ASAP!!!!
Mashcka [7]

For this case we have that by definition of power properties it is fulfilled that:

(a ^ n) ^ m = a ^ {n * m}

We must rewrite the following function:

f (x) = 7 (\frac {1} {2})^{3x}}

Using the mentioned property we have:

f (x) = 7 ((\frac {1} {2}) ^ 3) ^ x

Solving the operation within the parenthesis we have:

f (x) = 7 (\frac {1 ^ 3} {2 ^ 3}) ^{ x}\\f (x) = 7 (\frac {1} {8})^{x}

Thus, the correct option is option B

The slope is 35. The y-intercept is 550. what can you conclude?
MrRa [10]

Answer:

the formula is y = mx + b. (m) represents slope and (b) represents the intercept

Step-by-step explanation:

So with that formula and info given, you can form the equation y = 35x + 550

Solve the following equation. 6x−15=4x+55 6 x − 15 = 4 x + 55
algol [13]

Answer:

x = 35

Step-by-step explanation:

Solve for x:

6 x - 15 = 4 x + 55

Hint: | Move terms with x to the left hand side.

Subtract 4 x from both sides:

(6 x - 4 x) - 15 = (4 x - 4 x) + 55

Hint: | Combine like terms in 6 x - 4 x.

6 x - 4 x = 2 x:

2 x - 15 = (4 x - 4 x) + 55

Hint: | Look for the difference of two identical terms.

4 x - 4 x = 0:

2 x - 15 = 55

Hint: | Isolate terms with x to the left hand side.

Add 15 to both sides:

2 x + (15 - 15) = 15 + 55

Hint: | Look for the difference of two identical terms.

15 - 15 = 0:

2 x = 55 + 15

Hint: | Evaluate 55 + 15.

55 + 15 = 70:

2 x = 70

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 2 x = 70 by 2:

(2 x)/2 = 70/2

Hint: | Any nonzero number divided by itself is one.

2/2 = 1:

x = 70/2

Hint: | Reduce 70/2 to lowest terms. Start by finding the GCD of 70 and 2.

The gcd of 70 and 2 is 2, so 70/2 = (2×35)/(2×1) = 2/2×35 = 35:

Answer: x = 35
