Find JK................

Mathematics
1 answer:
Burka [1]3 years ago
6 0

Answer:

24 unit

Step-by-step explanation:

From the question,

JK = 2×NK.................... Equation 1

Using pythagoras theorem,

a² = b²+ c²................. Equation 2

From the diagram,

a = 15 unit, b = 9 unit, and c = NK

Substitute these values into equation 2

15² = 9²+(NK)²

Solve for NK

225 = 81+(NK)²

(NK)² = 225-81

(NK)²  = 144

NK = \sqrt{144}

NK = 12 unit.

Substitute these value of NK into equation 1

JK = 2×12

JK = 24 Unit.

Area codes have three digits. The first digit must not be 0 or 1, the middle digit must be 0 or 1, and the last digit must not b
disa [49]
There are 10 digits 0 1 2 3 4 5 6 7 8 9 if we can't use 0 and 1 then there are only 8 choices for the first digit and only 2 choices for the second digit and 10 for the third so there are 8*2*10 =160 possibilities. I think ???

A rocket is launched at t = 0 seconds. Its height, in meters above sea-level, is given by the equation
gogolik [260]

Answer:

Step-by-step explanation:

In order to find out how long it takes for the rocket to hit the ground, we only need set that position equation equal to 0 (that's how high something is off the ground when it is sitting ON the ground) and factor to solve for t:

0=-4.9t^2+112t+395

Factor that however you are factoring in class to get

t = -3.1 seconds and t = 25.9 seconds.

Since time can NEVER be negative, it takes the rocket approximately 26 seconds to hit the ground.

Which point is on the graph of f(x) = 3 x 5^x?
Harlamova29_29 [7]

Answer:

C

Step-by-step explanation:

To determine which point lies on the graph, substitute the x-coordinate into f(x) and if the value is equal to the y-coordinate then the point is on the graph

A (15, 1)

f(15) = 3 × 5^{15} ≠ 1 ← not on graph

B (0, 15)

f(0) = 3 × 5^{0} = 3 × 1 = 3 ≠ 15 ← not on graph

C (1, 15)

f(1) = 3 × 5^{1} = 3 × 5 = 15 ← lies on graph

D (0, 0)

f(0) = 3 × 5^{0} = 3 × 1 = 3 ≠ 0 ← not on graph
