The ratio table shows the costs for different amounts of bird seed. Find the unit rate in dollars per pound.

Maru [420]

Answer:

2.3 dollars

Step-by-step explanation:

Given:

Ratio table that shows the costs for different amounts of bird seed

To find: the unit rate in dollars per pound

Solution:

Amount (pounds) 5 10 15 20

Cost (dollars) 11.5 23 34.50 46

Here,

$\frac{5}{11.5}=\frac{50}{115}=\frac{10}{23}\\\\\frac{10}{23}=\frac{10}{23}\\\\\frac{15}{34.50}=\frac{1500}{3450}=\frac{150}{345}=\frac{30}{69}=\frac{10}{23}\\\\\frac{20}{46}=\frac{10}{23}$

Therefore,

$\frac{5}{11.5}=\frac{10}{23}=\frac{15}{34.50}=\frac{20}{46}$

Cost of 10 pounds = 23 dollars

So, cost of 1 pound = $\frac{23}{10}=2.3$ dollars

P1 = (1,5). P2 = (x,2) .p1p2=5

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's use distance formula :

$\qquad \sf \dashrightarrow \: \sqrt{(x - 1) {}^{2} + (2 - 5) {}^{2} } = 5$

$\qquad \sf \dashrightarrow \: {(x - 1) {}^{2} + ( - 3) {}^{2} } = 5 {}^{2}$

$\qquad \sf \dashrightarrow \:(x - 1) {}^{2} + 9 = 25$

$\qquad \sf \dashrightarrow \:(x - 1) {}^{2} = 16$

$\qquad \sf \dashrightarrow \:(x - 1) = 16$

$\qquad \sf \dashrightarrow \:(x - 1) = \pm4$

$\qquad \sf \dashrightarrow \:x = 5 \: \: or \: \: - 3$

What is limit of startroot x squared minus 8 endroot as x approaches negative 3? –5 1 startroot 2 endroot startroot negative 14

DochEvi [55]

The limit of $\lim_{x \to -3}\sqrt{ x^2-8}$ as x approaches negative 3 is 1

<h3>Limit of a function </h3>

The limit of the function given in question can also be written as:

$\lim_{x \to -3}\sqrt{ x^2-8}$

To determine the required limit, we will simply substitute the value of x into the function as shown:

$\lim_{x \to -3}\sqrt{ x^2-8}=\sqrt{ (-3)^2-8}\\\lim_{x \to -3}\sqrt{ x^2-8}=\sqrt{9-8}=1\\$

Hence the limit of $\lim_{x \to -3}\sqrt{ x^2-8}$ as x approaches negative 3 is 1
