what is the height of the tree?

Answer:

c)

6.1 x 5 = 30.5

6.1 + 12.9 = 19

19/2 = 9.5

9.5 x 10= 95

95 + 30.5 = 125.5 cm squared

d) 4.1 x 4.7 = 19.27

2.05 squared x pi = 13.5

13.5 /2 = 6.6

19.27 + 6.6 = 25.87 cm squared

e) 16 x 22 = 352

352/2= 176

pi x 11 squared = 95.03

95.03+176 = 271.03 cm squared

f) 8 x 8 =64

pi x 4 squared= 50.27

50.27 x 3 = 150.81

150.81 + 64 = 214.81cm squared

Answer:

2.61

Step-by-step explanation:

Cube the diameter. Multiply by the number pi. Divide by the number 12. 3.14 x 10 / 12 = 2.61 the original number is 2.61666666667 But to make it simple its 2.61

Answer: $24

Step-by-step explanation:

Since the popcorn combos are the same amount, we are essentially calculating the difference between 6 adult tickets and 6 student tickets.

6 adult tickets are $10*6 = $60, while 6 student tickets are $6*6 = $36.

60-36= $24

Using the normal distribution, it is found that:

a) The cutoff time for the fastest 5% of athletes in the men's group is of 3448.58.

b) The cutoff time for the slowest 10% of athletes in the women's group is of 6298.72.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Item a:

For men, we have that [tex]\mu = 4378, \sigma = 565[/tex].

The cutoff for the fastest 5% of the athletes is the 5th percentile, which is X when Z has a p-value of 0.05, that is, X when Z = -1.645.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-1.645 = \frac{X - 4378}{565}[/tex]

[tex]X - 4378 = -1.645(565)[/tex]

[tex]X = 3448.58[/tex]

The cutoff time for the fastest 5% of athletes in the men's group is of 3448.58.

Item b:

For women, we have that [tex]\mu = 5212, \sigma = 849[/tex].

The cutoff is the 90th percentile, which is X when Z = 1.28, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.28 = \frac{X - 5212}{849}[/tex]

[tex]X - 5212 = 1.28(849)[/tex]

[tex]X = 6298.72[/tex]

The cutoff time for the slowest 10% of athletes in the women's group is of 6298.72.

The sum of the sequence is 300

Given the sum of sequence;

∑n=(5n−7)

We are to get the sum of the sequence from n = 1 to n = 24

The formula for calculating the sum of the sequence is expressed as:

Sn = n/2(a+l)

Given the following parameters

a = 1

l = 24

n = 24

S24 = 24/2(1 + 24)

S24 = 12(25)
S24 = 300

Hence the sum of the sequence is 300

Step-by-step explanation:

Answer:

f(10) = 1100

given:

f(n) = 10(10x + 10)

solve:

f(10) = 10(10(10)+10)

f(10) = 10(100+10)

f(10) = 10(110)

f(10) = 1100

Answer:

1100

Step-by-step explanation:

f(n) = 10*(10x + 10)

f(n) = 100x + 100

f(10) = 100(10) + 100

f(10) = 1100

  (d)  -11

Step-by-step explanation:

Each of the functions is evaluated in the usual way: put the number where the variable is in the expression and simplify.

  h(-1) = -2(-1)² -3(-1) +1 = -2 +3 +1 = 2

  f(2) = (2(2) +7)/(2 -3) = 11/-1 = -11

Then f(h(-1)) is ...

  f(h(-1)) = f(2) = -11

Answer:

500$

Step-by-step explanation:

Answer:

-2/5 , -7/13 , 7/11 , 5/84

1. The answer would be "-15" since integers are composed of whole numbers and negatives.

2. The statement "Every real number is a rational number." is false, since real numbers are composed of both rational and irrational numbers.

3. The number "8.52624 . . ." because this is the only non-terminating number, which makes it the only irrational number on the list.

4. "Irrational numbers cannot be classified as rational numbers." is the only correct statement. No irrational numbers can be rational numbers, and the opposite is also true.

5. Only the statement "Every irrational number is a real number." is true.

Answer:

35

Step-by-step explanation:

let x be the number of students in the class

then number of girls = 0.4x , so

x = 21 + 0.4x ( subtract 0.4x from both sides )

0.6x = 21 ( divide both sides by 0.6 )

x = 35

the total number of students is 35

Answer:

(a) dp/dx = 90/(x+2)

(b) $2.25

(c) approx = $2.25

    exact = $2.22

Step-by-step explanation:

[tex]p = 20 + 90 \ln(2x + 4)[/tex]

(a) To find the rate of change, differentiate [tex]p[/tex] with respect to [tex]x[/tex] :

[tex]\implies \frac{d}{dx}(p) = \frac{d}{dx}(20) + \frac{d}{dx}(90 \ln(2x + 4))[/tex]

[tex]\implies \frac{dp}{dx}=0+90\times\dfrac{1}{2x+4}\times2[/tex]

[tex]\implies \frac{dp}{dx}=\dfrac{180}{2x+4}[/tex]

[tex]\implies \frac{dp}{dx}=\dfrac{90}{x+2}[/tex]

(b)  Find  [tex]\frac{dp}{dx}[/tex]  when [tex]x=38[/tex] :

[tex]\implies \frac{dp}{dx}=\dfrac{90}{38+2}[/tex]

[tex]\implies \frac{dp}{dx}=\dfrac{90}{40}[/tex]

[tex]\implies \frac{dp}{dx}=2.25[/tex]

(c)  Approximate price increase associated with the number of units supplied changing from 38 to 39 is  [tex]\frac{dp}{dx}[/tex]  when [tex]x=38[/tex]

[tex]\implies \$2.25[/tex]

Exact price increase:

[tex]\implies \left. p \right_{x=39}-\left. p \right_{x=38}\\\\\implies [20 + 90 \ln(2 \times 39 + 4)]-[20 + 90 \ln(2\times38 + 4)]\\\\\implies 416.6047323...-414.3823972...\\\\\implies 2.222335133...\\\\\implies \$2.22[/tex]
