Answer:
Step-by-step explanation:
[tex]d^2=(x_2-x_1)^2+(y_2-y_1)^2\\ \\ d^2=(-2-1)^2+(5-9)^2\\ \\ d^2=9+16\\ \\ d^2=25\\ \\ d=\sqrt{25}\\ \\ d=5[/tex]
Answer:
PQ = 5
Step-by-step explanation:
Distance Formula
d = [tex]\sqrt{(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2 }[/tex]
d = [tex]\sqrt{{(1} - -2)^2 + (9 - 5)^2 }[/tex]
d = [tex]\sqrt{3^2+4^2}[/tex]
d = [tex]\sqrt{9+16}[/tex]
d =[tex]\sqrt{25}[/tex]
d=5
PQ = 5

Ken jumps 1 1/5 metres and Steve jumps 1.5 metres. How much more does Steve jump?
Answer: 0.3 meters.
Step-by-step explanation:
First we need to turn one of those into a fraction or decimal to make things easier for us. Lets turn [tex]1 \frac{1}{5}[/tex] into a decimal.
1 1/5 as a decimal is 1.2.
Now we compare the two
[tex]1.5 > 1.2[/tex]
Now we need to subtract 1.5 by 1.2 to see how much more he jumps by.
[tex]1.5 - 1.2 = 0.3[/tex]
Steve jumps more by 0.3 meters.
Answer:
3/10 or .3 meters
Step-by-step explanation:
1 1/5 = 1.2
1.5 - 1.2 = 0.3

PLEASE HELP!!! Find the length of the missing side of the right triangle,
13 yd
Syd
A. 194 yd
B 13.93 yd
C. 144 ya
D. 12 yd
Answer:
12
Step-by-step explanation:
For these problems you should use the pythagorean theorem: a^2+b^2=c^2
In this case, 13=c and 5=a
so:
5^2+x^2=13^2
25+x^2=169
subtract 25 from both sides
x^2=144
√144=12
missing side=12

Grocery Store A is selling bananas for $0.75 for 12 pound. Grocery Store B is selling 5 pounds of bananas for $3.75.
Which store is offering the best unit rate? Show your work
Answer:
12 ×$0.75 =$8.00
3.75 ÷ 5 = $1.33 a pound,
$1.33 × 12 = $15.96 so store A is offering the best rate.
It is found that Store B is offering the best unit rate for the bananas.
What is unit rate?There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.
Given that Grocery Store A is selling bananas 1/2 pound for $0.75 .
Grocery Store B is selling 5 pounds of bananas for $3.75.
According to the question,
Store A is selling bananas 1/2 pound for $0.75 .
Therefore,
For one pound will be;
= 0.75/0.5
= 1.5
And store B is selling 5 pounds of bananas for; $3.75
Therefore,
One pound will cost;
3.75/ 5 = 0.75
Hence, Store B is offering the best unit rate for the bananas.

f(x) = {5x+2 if x grather than 2
f(3)
Answer choices
14
18
17
20
Answer:
17 is your answer
Step-by-step explanation:
Given a peicewise function, with two parts:
{f(x) = 4x+3 {if x<2}
f(x) = 5x+2 {if x>2}
f(3) = f(x) when x is 3, 3 > 2, 3 is not less than 2 so f(x) for x>2 is 5x + 2.
Therefore f(3) = 5(3) + 2 = 15 + 2 = 17

A fireman has 12 ft. ladder and a 16 ft ladder. He leans the 12 ft ladder against a house at an angle of 57 degrees. He leans the 16 ft ladder against a house 30-degree angle. Which ladder will he climb to the higher height? Explain you answer
Answer:
12 feet ladder
Step-by-step explanation:
Height of 12 ft ladder :
Using Pythagoras :
Tan θ = Adjacent / hypotenus
Tan 57 = h / 12
1.5398649 * 12 = 18.48 feets
For 16 feet ladder :
Tan θ = Adjacent / hypotenus
Tan 30 = h / 16
0.5773502 * 16 = 9.24 feets
18.48 > 9.24
Hence, he'll climb the 12 feets ladder to the higher height
