Answer:

4 sq units and 6 sq units

Step-by-step explanation:

Method:

count dots inside ...(a)

the ones on the border of the shape and divide by two ...(b)

(a)+(b)-1 = area

use that for green and yellow

Green:

(a): 0

(b): 10/2 = 5

0+5-1 = 4 sq units

Yellow:

(a): 3

(b): 8/2 = 4

3+4-1 = 6 sq units

I hope this helps, and plz mark me brainliest!!!!

Find the vertex of the parabola.<br> F(x) = 5x^2 - 30x +49
Juli2301 [7.4K]

X=-b/2a is the formula for finding the axis of symmetry
So x= -30/2(5)
X=-30/10
X=-3

Because the axis of symmetry is -3, we know where to place our line, and we also know that the parabola is open downwards, which means that the vertex will be maximum. To find the vertex, plug in your values with the axis of symmetry as a midway point. Plug that in for x and so you should have the following:
F(x)
Y(f(x) and y variables are interchangeable) =5(-3)^2-30(-3)+49

Solve for y(f(x))
5(-3)^2-30(-3)+49
(-3)^2=3^2
3^2*5+30*3+49
Multiply
3^2*5+90+49
Add numbers
3^2*5+139
9*5=45
45+139=184
Y=184

So, your vertex would be
(-3,184) and it would be maximum. From there you can plug in the rest of your table of values.

What is the exact simple interest on 150-day loan of 2,350 at %10
Crazy boy [7]

Answer:

  96.58

Step-by-step explanation:

The formula for simple interest is ...

  I = Prt

where P is the principal, r is the rate, and t is the time period in years.

Exact interest is computed using 365 days per year, so the time period is ...

  t = 150/365

Then the interest is ...

  I = 2350(0.10)(150/365) = 96.58
