Answer:

1. Yes; 2. Yes ; 3. No; 4. Yes

Step-by-step explanation:

The proportion will have to be read the same way. For example top Δ bottom to the lower Δ bottom (locate in the same place)

14/21 = 6 /9 Yes because the top Δ bottom to lower Δ bottom = top side to

lower same side

13.5/21 = 9/ 14 Yes because the same two sides to the same two sides in

the lower Δ

9/13.5 = 6 21 No because top Δ side to lower Δ same location but the

second one top Δ side to the lower bottom

14 /6 = 21/6 Yes because top Δ bottom to top side = lower Δ bottom to

lower side (in the same place)

A car traveling at a speed of 63 kilometers per hour. What is the car’s speed in meters per second? How many meters will the car

dezoksy [38]

Answer:

Speed = 1050 meters per seconds

Distance =10500 meters

Step-by-step explanation:

Car traveling at a speed of 63 kilometers per hour

Let us convert this into meter per second

Speed = $\frac{63 }{1}$ kilometers per hour

Speed = $\frac{63 \ kilometers }{1 \ hour}$ --------(A)

1 kilometer = 1000 meters

1 hours = 3600 seconds

Replacing them in (A)

Speed = $\frac{63 \times 1000 \ meters }{1 \times 60 \ seconds}$

Speed = $\frac{63 \times 1000}{1 \times 60}$ meters per seconds

Speed = $\frac{63000}{60}$ meters per seconds

Speed = 1050 meters per seconds

Distance = speed x time

Speed = 1050 mt per sec

time = 10 sec

Distance = 1050 x 10 = 10500 meters

Given the binomials (x - 3), (x - 1), (x + 2), and (x + 3), which one is a factor of f(x) = 2x3 + 3x2 - 2x - 3?

spayn [35]

Answer:

(x-1) is factor of our function.

Step-by-step explanation:

We are given a function $f(x)=2x^{3} +3x^{2} -2x-3$ and we are asked to find the correct factor from the given options.

Let us factor out our polynomial.

$2x^{3} +3x^{2} -2x-3$

$x^{2} (2x+3)-1(2x+3)$

$(x^{2} -1)(2x+3)$

$(x+1)(x-1)(2x+3)$

Therefore, (x-1) is correct choice for factor of our polynomial.
