Answer:

9 x 10^12

Step-by-step explanation:

for multiplying scientific notation, you multiply the numbers (3 x 3) and add the exponents together (6 + 6) to get 9 x 10^12

The function g(x) = x3 has the point (-3, -27) on its graph. The function g(x) is even or odd

sashaice [31]

Answer:

The function g(x) is odd.

Step-by-step explanation:

Even and odd functions:

If for every value of x, f(x) = f(-x), the function is even.

If for every value of x, f(x) = -f(x), the function is odd.

If those statements are false, the function is neither even nor odd.

In this question:

$g(x) = x^{3}$

$g(-x) = (-x)^{3} = -x^{3} = -g(x)$

Since g(x) = -g(-x), the function g(x) is odd.

Olivia kicks a soccer ball from the ground with an initial vertical velocity of 15 m/s. Which equation can be used to find the t

babunello [35]

Answer:

The answer is below

Step-by-step explanation:

Motion shows the change in the position of an object over time. This change is showed in terms of displacement, distance, velocity, acceleration, time and speed. The equations of motion shows this relationship.

Since the soccer ball is kicked up with an initial velocity (u) of 15 m/s, the acceleration due to gravity (g) acts on the ball. If the ball is kicked at an angle Θ, the time t it takes for the ball to reach the ground is:

$t=\frac{2u*sin(\theta)}{g} \\\\t=\frac{2(15)*sin(\theta)}{g} \\\\t=\frac{30*sin(\theta)}{g} \\\\If\ it\ is\ kicked\ vertical\ then\ \theta=90^0,hence:\\\\t=\frac{30*sin(90)}{g}= \frac{30}{g }$

A random sample of 420 new Ford trucks showed that 105 required repairs within the first warranty year.What is the estimate for

zvonat [6]

The probability of an event P(n), is equal to the number of the outcomes of that event n(E), divided by the total number of outcomes, or the sample space, n(S)

so $P(n)= \frac{n(E)}{n(S)}$

$P(truck need rapair within the first year)=$

$\frac{n(truck need rapair within the first year)}{n(trucks)} = \frac{105} {420}= 0.25$

The probability of an event = 1 - probability of the same event not to happen

so P(not need repair within the first year)=1-0.25=0.75

Answer: a) 0,25; b) 0,75
