A submarine lies 3 kilometers from the path of a target ship. The sub’s torpedoes have a range of 5 kilometers. For what distanc

aev [14]

The distance along the path of the ship be within the range of the torpedoes is 4 kilometers.

Explanation:

The submarine lies 3 km from the target ship.

Let B denotes the target ship and C denotes the submarine.

Let AC denotes the the target ship would be within the range of the torpedoes.

The image attached below illustrates that the distance between submarine and the target ship and the range of the torpedoes.

Let BC denotes the distance between the target ship and the submarine. Let AC denotes the range of the torpedoes.

To determine the length of AB, let us use Pythagorean theorem,

$AC^{2} =AB^{2} +BC^{2}$

Substituting the values of BC = 3 and AC = 5, we have,

$5^{2} =AB^{2} +3^{2}$

Squaring the terms, we get,

$25 =AB^{2} +9$

Subtracting both sides by 9, we have,

$16 =AB^{2}$

Taking square root on both sides,

$AB = 4$

Thus, the distance along the path of the ship be within the range of the torpedoes is 4 kilometers.

I need 9-12 please!!

9:
-q^2 - r^2 + 3s

-9^2 - -6^2 + 3(-20)

-9^2 = -9 * -9 = 81

81 - -6^2 + 3(-20)

-6^2 = -6 * -6 = 36

81 - 36 + 3(-20)

3(-20) = -60

81 - 36 + -60

81 + 36 = 117

117 + (-60)

117 - 60= 57

57

10:
3| x + y |^2 - (xy)^2

3| 3 + -5 |^2 - (3-5)^2

(3-5) = 2

3| 3 + -5 |^2 - 2^2

|3 + -5| = 8

3|8|^2 - 2^2

8 * 8 = 64

3(64) - 2^2

2^2 = 2*2 = 4

3(64) - 4

3*64 = 192

192 - 4 = 188

188

11:
2x^2 - 5xy - y^3

2(-3)^2 - 5(-3-2) - -2^3

(-3-2) = -5

2(-3)^2 - 5(-5) - -2^3

-3^2 = -3 * -3 = -9

2(-9) - 5(-5) - -2^3

2^3 = 2 * 2 * 2 = 8

2(-9) - 5(-5) - 8

18 - 5(-5) - 8

5(-5) = -25

18 - (-25) - 8

18 + 25 - 8

18 + 25 = 43

43 - 8 = 35

35

12: -a^2 + 7b^4 -2c^3

—4^2 + 7(-2)^4 - 2(-3)^3

4^2 + 7(-2)^4 - 2(-3)^3

4 * 4 = 16

16 + 7(-2)^4 - 2(-3)^3

-2 * -2 * -2 * -2 = 16

16 + 7(16) - 2(-3)^3

-3 * -3 * -3 = -27

16 + 7(16) - 2(-27)

7 * 16 = 112

16 + 112 - 2(-27)

2 * -27 = -54

16 + 112 - -54

16 + 112 + 54

112 + 16 = 128

128 + 54 = 182

182

Find the equation of a line that is perpendicular to 4y-3x=1 and passes through point (-7,0).

Mnenie [13.5K]

Answer:

-4/3x + -28/3

Step-by-step explanation:

First you rearrange 4y-3x=1

y= 3/4x +1/4

then you reciprocate and change the sign the slope since you are trying to find a line perpendicular to it.

Slope(m) =-4/3

then you use the formula <em>y-y1= m(x-x1)</em>

y-0= -4/3 (x--7)

y= -4/3 +-28/3

Answer:

33 cubic unit

Step-by-step explanation:

Volume of the prism = base area * height

= 9 * 3 2/3 {Change improper to proper fraction}

$= 9*\frac{11}{3}\\\\= 3* 11\\\\= 33 unit^{3}$

Solve the equation below. Simplify if necessary.

SpyIntel [72]

Answer:

15 1/6

Step-by-step explanation:

change -8 2/3 into an improper fraction = -26/3

-4/7v = -26/3

cross-multiply:

3(-4v) = (-26)7

-12v = -182

v = 182/12

v = 15 1/6
