During the school year, each student planted 2 x 10^2 trees as part of a community service project. If there are 3.5 x 10^3 stud
amm1812

Answer:

Total number of trees planted =  7\times 10^{5} trees

Step-by-step explanation:

Trees planted by each student = 2\times 10^2

Total number of students = 3.5\times 10^3

Using unitary method to find total number of trees planted by all the students in school.

1 student plants = 2\times 10^2 trees

3.5\times 10^3 student would plant = (2\times 10^2)\times (3.5\times 10^3)

We apply the product rule of exponents to multiply [a^xa^y=a^{x+y}]

⇒ (2\times 3.5)\times(10^2\times 10^3)

⇒ 7\times 10^{2+3}

⇒ 7\times 10^{5} trees

Total number of trees planted =  7\times 10^{5} trees

I need help, urgently.
Korvikt [17]

Answer:

y = -0.5(x - 4)^2 + 5.

y = -0.5x^2 + 4x - 3.

Step-by-step explanation:

The vertex is at (4, 5).  so we have:

f(x) = a(x - 4)^2 + 5

When x = 0 y = -3 so substituting in the above:

- 3 = a(0-4)^2 + 5

-8 = 16a

a = -0.5.

So the vertex form is y = -0.5(x - 4)^2 + 5.

Standard form:

y = -0.5(x^2 - 8x + 16) + 5

y = -0.5x^2 + 4x - 8 + 5

y = -0.5x^2 + 4x - 3.
