Answer:

b ≈ 9.5, c ≈ 14.7

Step-by-step explanation:

Using the Sine rule in Δ ABC, that is

\frac{a}{sinA} = \frac{b}{sinB} , substitute values

\frac{7}{sin23} = \frac{b}{sin32} ( cross- multiply )

b × sin23° = 7 × sin32° ( divide both sides by sin23° )

b = \frac{7sin32}{sin23} ≈ 9.5 ( to the nearest tenth )

Also

\frac{a}{sinA} = \frac{c}{sinC}

\frac{7}{sin23} = \frac{c}{sin125} ( cross- multiply )

c × sin23° = 7 × sin125° ( divide both sides by sin23° )

c = \frac{7sin125}{sin23} ≈ 14.7 ( to the nearest tenth )

Find the sum using the formulas for the sums of powers of integers ( problem attached )
Natasha2012 [34]

Correct Answer: - 550

We can use the distributive property to distribute the summation to the variables and then get the constant out to apply the summation formulas as shown below in the attached image.

The equation editor does not have a summation symbol, so I have attached the solution using the image.

The correct answer to this question is -550. First option is the correct one.

Answer:

(-15, 13)

Step-by-step explanation:

-3(8x + 9y = -3)

4( 6x + 7y = 1)

-24x - 27y = 9

24x + 28y = 4 (add both equations)

y = 13

6x + 7*13= 1

6x + 91= 1

6x = 1 -91

x = -91/6

x = -15

An island has some portion submerged in water. Point A on the island is at negative 7 over 3 feet from the surface of the sea. P
sashaice [31]

Answer:

1/6feet

Step-by-step explanation:

Given

Point A on the island = -7/3 feet from the sea surface

Point B on the island = -5/2 from the sea surface

The distance between the two points will be Point A - Point B

Distance between the two points = -7/3 - (-5/2)

= -7/3+5/2

Find the LCM

= {2(-7)+3(5)}/6

= -14+15/6

= 1/6

Hence the distance of the two points from the surface of the sea is 1/6feet
