Answer:

Step-by-step explanation:

time, t  = 10 seconds

initial velocity, u = 10 m/s

final velocity, v = 20 m/s

acceleration, a = v - u / t

= 20 - 10 / 10

= 10 / 10

<u><em>= 1 m/s^2</em></u>

Hope this helps

ANSWER

Options B, C and D have exactly 2 significant figures.

To see whether the numbers have exactly 2 significant figures, round all to 2 significant figures. The ones that remains the same have exactly 2 significant figures.


302\approx 300yards to 2.s.f

980\approx 980gallons to 2.s.f

1200\approx 1200feet to 2.s.f

84\approx 84litters to 2.s.f\

Anit [1.1K]

Answer:

There are 120 1st graders at Sierra Elementary School this year

Step-by-step explanation:

Let n represent the total number of 1st graders at Sierra Elementary School

Since 45% of all 1st graders at Sierra Elementary School are female students and this year there are 54 female 1st graders, 45% of n is equal to 54

→ n(\frac{45}{100}) = 54

→ 45n = 5400

→ n = 120

Find the equation of quadratic function determined from the graph below?
Aleksandr [31]

Step-by-step explanation:

The x-intercepts are x = -1 and x = 5, so:

y = k (x + 1) (x − 5)

The vertex is (2, -3), so:

-3 = k (2 + 1) (2 − 5)

-3 = -9k

k = 1/3

y = 1/3 (x + 1) (x − 5)

Simplifying:

y = 1/3 (x² − 4x − 5)

y = 1/3 x² − 4/3 x − 5/3
