Answer:

Step-by-step explanation:

Given the line of best fit

y = - 9.21x + 168.7

Substitute the weight of the pumpkin , that is x = 5, into the equation.

y = - 9.21(5) + 168.7

= - 46.05 + 168.7

= 122.65 ≈ 123 feet ( to the nearest foot )

Limits
Limit Rule [Variable Direct Substitution]: $\displaystyle \lim_{x \to c} x = c$
Limit Property [Multiplied Constant]: $\displaystyle \lim_{x \to c} bf(x) = b \lim_{x \to c} f(x)$
Derivatives
Definition of a Derivative: $\displaystyle f'(x) = \lim_{h \to 0} \frac{f(x + h) - f(x)}{h}$

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle g(x) = \lim_{h \to 0} \frac{f(x + h) - f(x)}{h}$

$\displaystyle f(x) = \frac{3}{\sqrt{x - 4}}$

$\displaystyle g(29)$

Step 2: Differentiate

Substitute in function [Function g(x)]: $\displaystyle g(x) = \lim_{h \to 0} \frac{\frac{3}{\sqrt{x + h - 4}} - \frac{3}{\sqrt{x - 4}}}{h}$
Substitute in x [Function g(x)]: $\displaystyle g(29) = \lim_{h \to 0} \frac{\frac{3}{\sqrt{29 + h - 4}} - \frac{3}{\sqrt{29 - 4}}}{h}$
Simplify: $\displaystyle g(29) = \lim_{h \to 0} \frac{\frac{3}{\sqrt{25 + h}} - \frac{3}{5}}{h}$
Rewrite: $\displaystyle g(29) = \lim_{h \to 0} \frac{\frac{15}{5\sqrt{25 + h}} - \frac{3\sqrt{25 + h}}{5\sqrt{25 + h}}}{h}$
[Subtraction] Combine like terms: $\displaystyle g(29) = \lim_{h \to 0} \frac{\frac{15 - 3\sqrt{25 + h}}{5\sqrt{25 + h}}}{h}$
Factor: $\displaystyle g(29) = \lim_{h \to 0} \frac{\frac{3(5 - \sqrt{25 + h})}{5\sqrt{25 + h}}}{h}$
Rewrite: $\displaystyle g(29) = \lim_{h \to 0} \frac{3(5 - \sqrt{25 + h})}{5h\sqrt{25 + h}}$
Rewrite [Limit Property - Multiplied Constant]: $\displaystyle g(29) = \frac{3}{5} \lim_{h \to 0} \frac{5 - \sqrt{25 + h}}{h\sqrt{25 + h}}$
Root Conjugation: $\displaystyle g(29) = \frac{3}{5} \lim_{h \to 0} \frac{5 - \sqrt{25 + h}}{h\sqrt{25 + h}} \cdot \frac{5 + \sqrt{25 + h}}{5 + \sqrt{25 + h}}$
Multiply: $\displaystyle g(29) = \frac{3}{5} \lim_{h \to 0} \frac{-h}{5h\sqrt{25 + h} + h^2 + 25h}$
Factor: $\displaystyle g(29) = \frac{3}{5} \lim_{h \to 0} \frac{-h}{h(5\sqrt{25 + h} + h + 25)}$
Simplify: $\displaystyle g(29) = \frac{3}{5} \lim_{h \to 0} \frac{-1}{5\sqrt{25 + h} + h + 25}$
Evaluate limit [Limit Rule - Variable Direct Substitution]: $\displaystyle g(29) = \frac{3}{5} \lim_{h \to 0} \frac{-1}{5\sqrt{25 + 0} + 0 + 25}$
Simplify: $\displaystyle g(29) = \frac{3}{5} \cdot \frac{-1}{50}$
Multiply: $\displaystyle g(29) = \frac{-3}{250}$

Abi and Ali shared £35 in the ratio 1 : 6. Work out how much Ali received.

baherus [9]

Answer:

£30

Step-by-step explanation:

To tackle these 'sharing' ratios problems, first find the total amount parts in the ratio.

1 : 6 = 1 + 6 = 7 parts

Now divide the total amount of parts by the total amount of money shared

35 / 7 = 5

Now multiply the answer by the value that is appropriate.

In this case, they want you to work out how much Ali recieved.

Ali's value is 6

6 × 5 = £30

hope this helps :)

Fraction question...pls help out!!!

pentagon [3]

The answer is D because, as decimals, 4 1/3 would be 4.33(a repeating decimal) and 4 3/5 would be 4.6, and 4.4 is between those two numbers. I hope this helps.

Alison has 1/2 cup of yogurt for making grit parfaits. Each parfait requires 1/8 cup of yogurt. How many parfaits can she make?

Vedmedyk [2.9K]

Alison can make 4. Because 1/2 of 8/1 = 4 if you cross out 2 and 8 so it would be 1/1 of 4/1
