Answer:
x = 54
Step-by-step explanation:
These angles are complementary because they add up to 90:
x - 7 + 43 = 90
x + 36 = 90
x = 90 - 36
x = 54
Step-by-step explanation:
Use the height equation:
y = ½ a t² + v t + h
where y is the height at time t,
a is the acceleration due to gravity,
v is the initial velocity,
and h is the initial height.
Here, a = -16, v = 0, and h = 90.
y = -8t² + 90
When the egg lands, y = 0.
0 = -8t² + 90
8t² = 90
t² = 45/4
t = 3.35
It takes approximately 3.35 seconds for the egg to land.
Hi, the answer is ;
Answer:
12 dimes and 27 nickels
Step-by-step explanation:
.05N + .1d = 2.55
N= 3d - 9
0.05 (3d-9) + 0.1d = 2.55
0.15d - 0.45 + 0.1d = 2.55
0.25d = 2.55 + 0.45
0.25d = 3
D = 12
N = 3 (12) - 9
N = 36 - 9
N = 27
Answer:
See attached image for the graph of the function
Step-by-step explanation:
Notice that this is the product of a power function () times the trigonometric and periodic function cos(x). So the zeros (crossings of the x axis will be driven by the values at which they independently give zero. That is the roots of the power function (only x=0) and the many roots of the cos function: , and their nagetiva values.
Notice that the blue curve in the graph represents the original function f(x), with its appropriate zeros (crossings of the x-axis), while the orange trace is that of "-f(x)". Of course for both the zeroes will be the same, while the rest of the curves will be the reflection over the x-axis since one is the negative of the other.
