Hey there!

So, when finding a congruent angle, when would need to find on the shape, which one's look congruent, ofcourse.

So by looking at them,

$(ST) \ and \ also \ (WX) \ seem \ to \ be \ congruent$

There are both (3,2) ; (1,3), even thought they're are in opposite quadrants.

Hope this helps!

The table shows the height of a soccer ball that has been kicked from the ground over time. (For reference: h(t) = 144 – 16t2) T

adoni [48]

Answer : option D

The rate of change is not constant and increases then decreases over time. The height of the ball above ground gets larger until 1.25 seconds and then gets smaller after that time.

Rate of change is nothing but the slope

To find slope we use formula $\frac{Change in height }{change in time}$

Time (seconds) Height (feet) Rate of change

0 -------------------------0

0.5 -----------------------16 -------------------- $\frac{16-0}{0.5-0} =32$

1 ----------------------24 -------------------- $\frac{24-16}{1-0.5} =16$

1.25 -----------------------25-------------------- $\frac{25-24}{1.25-1} =4$

1.5 -------------------------24 -------------------- $\frac{24-25}{1.5-1.25} =-4$

2 ----------------------------16 -------------------- $\frac{16-24}{2-1.5} =-16$

2.5 -------------------------0 -------------------- $\frac{0-16}{2.5-2} =-32$

Rate of change is positive till 1.25 seconds and then it becomes negative. From this it is clear that, the rate of change is not constant and increases then decreases over time. The height of the ball above ground gets larger until 1.25 seconds and then gets smaller after that time.

8 less than the product of 5 and-4

alina1380 [7]

So it says 8 less than, meaning 8 minus the product of 5 and -4, so literally it means subtract 8 from 5X-4
8-5*-4

Find the nth term of this number sequence<br> 18, 16, 14, 12,...<br> Pls help

hodyreva [135]

Step - by - step - explanation

So first find out the pattern. As you can see it just minuses 2 each time. So first

18, 16, 14, 12 (then minus another 2) equals 10, 8, 6, 4, 2.

So 2 is the ninth of the pattern, so 2 will be your answer.

Hope this helps.
