Answer:
C
Step-by-step explanation:
When you are given any number to an exponent, you need to multiply it by itself as many times as the exponent's number. For example, if you got 4^7, you would multiply 4 * 4 * 4 * 4 * 4 * 4 *4 for a total of 7 times. In this case, it is 1/2 * 1/2 * 1/2 because the exponent is 3, meaning you do that 3 times.
Standard form Ax + By = C
so
<span>(y - y1) = m(x - x1)
</span>given (5, -7) and m = -1/5
so
y + 7 = -1/5(x - 5)
-5y - 35 = x - 5
x + 5y = -30
answer
d. x + 5y = -30
For the seagull to catch the crab, h(t)=g(t) so:
-16t^2+45=-13t+23 add 16t^2 to both sides
45=16t^2-13t+23 subtract 45 from both sides
16t^2-13t-22=0 using the quadratic equation:
t=(13±√1577)/32, since t>0
t=(13+√1577)/32 seconds
t≈1.65 seconds (to nearest hundredth of a second)
And the height that this occurs using either original equation is:
h((13+√1577)/32)≈1.59 ft (to nearest hundredth of a foot)
