Answer:

3.5m

Step-by-step explanation:

Volume of pyramid = lwh÷3

25.77 = [(4.7)² × x] ÷ 3

25.77 × 3 = 22.09x

77.31 = 22.09x

x = 77.31 ÷ 22.09

= 3.49

= 3.5m

use a numerical method to estimate the value of the limit (if it exists.) Lim e^5t -1 /t as x tends to 0 from both sides​
charle [14.2K]

Hello from MrBillDoesMath!

Answer:

5

Discussion:

Consider the expansion of e^x:

e^x = 1 + x + x^2/2 + x^3/6 +......            =>      replace x by 5t

e^(5t) = 1 + (5t)  + (5t)^2/2 + ....              =>      subtract 1 from both sides

e^(5t) - 1 = (5t) + (5t)^2/2+....                  =>      divide both sides by t

(e^(5t) -1)/ t = 5 + (25/2)  t +....

so as t ends to 0  the quotient tends to    

5 + (25/2)0 + (other terms) *0   ->   5

Thank you,

MrB

Andre45 [30]

Answer:

Aaron=1188

Beth=1782

Charlie=2970

Step-by-step explanation:

From the question we are told that

Ratio 6:9:15

Total amount to e shared N=£5940

Generally the Ratio can divide the Total amount mathematically as follows

Ratio

6:9:15/3=2:3:5

Sum of ratio

2+3+5=10

For Aaron

A=\frac{2}{10} *5940

A=1188

For Beth

B=\frac{3}{10} *5940

B=1782

For Charlie

C=\frac{2}{10} *5940

C=2970

Check answer

A+B+C=5940\\1188+1782+2970=5940

Person BMI Total Cholesterol
dlinn [17]
By using the arithmetic sequence, the difference between every other age is 12.98 (interval is 2). Example: 20 and 22 has 157.87 and 170.85 respectively which has the mentioned difference. Hence, if we calculate for the person who has a BMI of 35, then we add 12.98 to 235.75 plus the half which is 6.49. The total is <span>255.22. The answer is C.</span>
