Help with this pleaseee

Mathematics
1 answer:
BartSMP [9]3 years ago
7 0

Answer:

29 units²

Step-by-step explanation:

You could divide this into two triangles and two trapezoids to find the area.  But since the majority of these are either whole or half squares, I‘d count those.  Then you’d just have one triangle in the top right corner.

Whole squares: 21

Half Squares: 10 (so 4 square units)

Triangle: 1/2(b)(h)=1/2(5)(2)=5

TOTAL = 21+4+5= 29 units²

F’(x)= 1+3 square root x f(9)=68
notka56 [123]

Answer:

f(x) = x + 2x^\frac{3}{2} + 5

Step-by-step explanation:

I'm assuming the question here is asking for f(x)

The first step would be to find the antiderivative of f'(x)

\int{1+3\sqrt{x}} \, dx = \int{1 + 3x^\frac{1}{2}} dx

Apply the reverse power rule

x + 2x^\frac{3}{2} + C

Now solve for C when x = 9

x + 2x^\frac{3}{2} + C = 68\\9 + 2(9)^\frac{3}{2} + C = 68\\9 + 2(27) + C = 68\\9 + 54 + C = 68\\63 + C = 68\\C = 5

Now substitute into the antiderivative

f(x) = x + 2x^\frac{3}{2} + 5

Susan has a collection of 65 nickels and dimes. If the number of nickels is four times the number of dimes, how many nickels and
NikAS [45]

Answer:

d = 13 and n = 52

Step-by-step explanation:

Number of dimes:  d

Number of nickels:  n

Then d + n = 65, and n = 4d

Substituting 4d for n in the first equation, we get:

d + 4d = 65, or 5d = 65.  Then d = 13 and n = 52

Descomp´on 16 en suma de dos n´umeros con producto maximo
Iteru [2.4K]

The decomposition of 16 that will give a higher multiplication value is 8 and 8 and this gives 8 × 8 = 64.

<h3>How to illustrate the information?</h3>

The information is simply about the value of the number 16 than when added gives 16 bit gives the highest multiplication value.

In this case, one. can note that 8 plus 8 will be;

= 8 + 8 = 16

Also, the multiplication will be:

= 8 × 8

= 64

Therefore, eight multiplied by eight will give the highest multiplication value.
