circumference and area

Answer:

-29+7i

Step-by-step explanation:

(5+2i)(-3+i)

-15+5i-6i+2i²

i²=-1

Simplify

-17-i

Add c

c=4i(2+3i)

=8i+12i²

=8i-12

-17-i+8i-12

-29+7i

well, from the picture, we can see the cylinder has a diameter of 5 and thus it has a radius of half that, or 2.5, and a height of "h", so

[tex]\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=2.5 \end{cases}\implies V=\pi (2.5)^2 h[/tex]

The inequality represents the sentence below is that the p minus 1. 4 greater-than 9.

Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.

Given that the difference of a number and one and four tenths is more than nine and seventy-eight hundredths.

Before solving it, first let's discuss the tenth and hundredths,

Here, the sentence given that the difference of a number and one and four tenths is more than nine and seventy-eight hundredths.

One and four tenths can be written as,

[tex]1\dfrac{4}{10}[/tex]

Nine and seventy-eight hundredths can be written as,

[tex]9\dfrac{78}{100}[/tex]

Let suppose the number is p. This difference of this number and one four tenths is more than nine and seventy-eight hundredths. Thus,

[tex]p-1\dfrac{4}{10} > 9\dfrac{78}{100}\\p-\dfrac{14}{10} > \dfrac{978}{100}\\p-1.4 > 9.78\\[/tex]

Hence, the inequality represents the sentence below is that the p minus 1. 4 greater-than 9.

Answer:

24.6

Step-by-step explanation:

to find x:

Add 4.6 to both sides so 20+4.6= 24.6

Find the value of x in 20 = x-4.6

x = 24.6

Given that,

bringing the variables left side and the constants the right side,

now, in order to find the value of the given variable,we'll add the constants,

Hence, 24.6 is the required solution to the equation

To verify whether our answer is correct,

we'll insert the value of the variable at it's place and check if LHS = RHS

Answer:

14 Wood

Step-by-step explanation:

50/5 = 10 Wood = 4 days

70/5 = 14 Wood = 6 Days

I hope this is correct!

105  cords of wood could 7 woodchucks chuck in 6 days

Two or more expressions with an Equal sign is called as Equation.

If 5 woodchucks could chuck 50 cords of wood in 4 days, and since 1 woodchuck chucks 1/5 as much wood as 5 woodchucks, then we know that.

1 woodchuck could chuck 10 cords of wood in 4 days.

Then, since a woodchuck can chuck 1/4 as much wood in 1 day as she can chuck in 4 days, we conclude that

1 woodchuck could chuck 2.5 cords of wood in 1 day.

Now we use this to find the answer of our problem. If

In one day, If 1 woodchuck could chuck 2.5 cords of wood, then

In six days ,1 woodchuck could chuck cords of wood=6×0.25

7 woodchucks could chuck cords of wood in 6 days=6×0.25×7

=105

Hence 105  cords of wood could 7 woodchucks chuck in 6 days

Even though there are more people visiting the lodge now than there were five years ago, the lodge is making less money than it did five years ago due to inflation.

Thus, the fact that the Lodge has not increased its prices implies, in principle, a maintenance of the profit. Now, given that the costs necessary for the normal operation of the Lodge increase, on average, by 3% per year, the Lodge's profit margins will have been reduced by 15% in 5 years (5 x 3 = 15).

Then subtract your answer (56) from the number of toy cars he gave away to Wayne and his sister: 56-46-5=5

Therefore, Darrel has 5 toy cars left.

Have a nice day! :)

Answer:

Darrell has 5 toy cars left

Step-by-step explanation:

So he started with 13.

13

He buys 22 cars from the toy store.

+22

He gets 21 cars for his birthday.

+21

13 + 22 + 21 = 56

He has 56.

But he then gave 5 of them to his sister.

-5

He then gives 46 to his friend Wayne.

-46

56 - 5 - 46 = 5

He currently has 5 toys left.

According to the vertex and the directrix of the given parabola, the equation is:

[tex]y = \frac{3}{4}(x - 1)^2 + 4[/tex]

The equation of a quadratic function, of vertex (h,k), is given by:

[tex]y = a(x - h)^2 + k[/tex]

In which a is the leading coefficient.

The directrix is at y = k + 4a.

In this problem, the vertex is (1,4), hence:

[tex]h = 1, k = 4[/tex]

The directrix is at y = 7, hence:

[tex]4 + 4a = 7[/tex]

[tex]a = \frac{3}{4}[/tex]

Hence, the equation is:

[tex]y = a(x - h)^2 + k[/tex]

[tex]y = \frac{3}{4}(x - 1)^2 + 4[/tex]
