Answer:
True, they form a proportion because their cross-multiplication products are equal.
Step-by-step explanation:
True or False?
If they are a proportion, the products you get from cross-multiplying are the same.
Multiply the left numerator by right denominator:
49 X 12 = 588
Multiply the left denominator by right numerator:
21 X 28 = 588
588 = 588
Therefore it is true, 49/21 and 28/12 form a proportion.
Hypotenuse = √[ (3)^2 + (-2)^2] = √13
sin(x) = -2/√13
csc(x) = 1 / sin(x) = - √13 / 2
cot (x) = 3 / (-2) = -3 / 2

Answer:
√3
Step-by-step explanation:
The ratio of the short sides to the hypotenuse in an isosceles right triangle is ...
1 : 1 : √2
This means ...
p·√2 = √6
p = (√6)/(√2) = √(6/2)
p = √3
Simply plug in the value of x into the function... f(0) = -7(0) + 3 = 3... f(5) = -7(5) + 3 = -32
the distance the child travels n swings after the first is . Options A) and D) are identical , so kindly match with your answer !
<u>Step-by-step explanation:</u>
Here we have , A child on a swing is pushed just once. The child moves a distance of 10 feet the first swing, and then only 83% as much as the previous swing for each one after. We need to find Which of the following sequences expresses the distance the child travels n swings after the first . Let's find out:
Initially the distance is 10 feet from after the first swing . It's given that there is 83% as much as previous distance !
For first swing :
⇒
For second swing :
⇒
For third swing :
⇒
⇒
So , For n swings :
⇒
Therefore , the distance the child travels n swings after the first is .
