Answer:
The Pythagorean theorem consists of a formula a^2+b^2=c^2 which is used to figure out the value of (mostly) the hypotenuse in a right triangle. The a and b are the 2 "non-hypotenuse" sides of the triangle (Opposite and Adjacent).
Answer:
Step-by-step explanation:
Used t find missing side angles when two sides are present. For example, if you have a short leg and a long leg, you can use the Pythagorean Theorem to find the hypotaneus and vse versa, using it to find the short or long leg if the other two are given.
Given the first term and the common ratio of a geometric
sequence find the first five terms and the explicit formula. a1
= 0.8, r= −5
Answer:
nth term = 0.8 * -5^(n - 1)
First five terms are: 0.8, -4,
20, -100, 500
Step-by-step explanation:
First term, a1 = 0.8
Common ratio, r = -5
a1 = 0.8
Second term = ar
= 0.8 * -5
= -4
Third term = ar²
= 0.8 * -5²
= 0.8 * 25
= 20
Fourth term = ar³
= 0.8 * -5³
= 0.8 * -125
= -100
Fifth term = ar⁴
= 0.8 * -5⁴
= 0.8 * 625
= 500
First five terms are: 0.8, -4,
20, -100, 500
nth term = ar^(n - 1)
= 0.8 * -5^(n - 1)
nth term = 0.8 * -5^(n - 1)

Michele is making a kite based on the pattern below. About how much binding does Michele need to cover the edges of the kite?
Answer:
about 52.1 in.
Step-by-step explanation:
PM=PE=5 inches, PR=4 inches, and OP=19 inches.
Since the figure is a kite, the diagonals ME and OR are perpendicular and form right triangles with their hypotenuses forming the sides of the kite, OM, MR, RE, and EO.
The figure shows the same kite O M R E as in the beginning of the task. Diagonal O R is perpendicular to diagonal M E.
Use the Pythagorean Theorem to calculate the length of OM.
OM=OP2+PM2−−−−−−−−−−√
Substitute 19 for OP and 5 for PM.
OM=192+52−−−−−−−√
=361+25−−−−−−−√
=386−−−√
Therefore, OM=386−−−√ in.
By the definition of a kite, OM≅EO. So, EO is also equal to 386−−−√ inches.
Use the Pythagorean Theorem to calculate the length of MR.
MR=PM2+PR2−−−−−−−−−−√
Substitute 5 for PM and 4 for PR.
MR=52+42−−−−−−√
=25+16−−−−−−√
=41−−√
Therefore, MR=41−−√ in.
By the definition of a kite, MR≅RE. So, RE is also equal to 41−−√ inches.
The figure shows the same kite O M R E as in the beginning of the task. Sides O M and E O are square root of 386 inches long. Sides M R and R E are square root of 41 inches long.
The perimeter of the kite is the sum of the four sides.
Perimeter of OMRE=OM+MR+RE+EO
=386−−−√+41−−√+41−−√+386−−−√
=2386−−−√+241−−√
Use a calculator to approximate.
Perimeter of OMRE≈52.1 in.
So, the perimeter of OMRE is about 52.1 inches.
Therefore, about 52.1 inches of binding are needed to cover the edges of the kite.

Pls help me with this work
Answer:
They are similar because they both have like terms in parenthesis.
Step-by-step explanation:
As long as you have like terms, the equation is the same. You never have to worry about the number before the variable being the same. As long as the variable is the same, you have like terms and that is like terms in the equation. TO SUM IT UP: They both have like terms and that is why they are similar.
9. DOG WALKING Evan, a dog walker, charges $3 every block that he walks a dog. He also charges a $5 pick up fee when he comes to get a dog. How many blocks will he need to walk a dog in order to earn $26? Write an equation and solve the equation.
Answer:
Evan will have to walk 7 blocks
Step-by-step explanation:
Evan will have to walk 7 blocks because he gets $5 from picking up the dog, so subtract 5 from 26 to get 21. Next, you want to divide 21 by 3 to get 7 because $3 a block and you need to find how many blocks he needs to do.

The cost of a 9 litter of petrol is $ 378. How much is 15 litres of petrol cost ?
Answer:
$630
Step-by-step explanation:
cost of each litter of petrol 378/9=42
cost of 15 liters of petrol 42x15=630
15 litters of petrol cost $630
Answer: $630
Step-by-step explanation:
[tex]9l[/tex] = $[tex]378[/tex]
[tex]\frac{378}{9}[/tex] to find [tex]xl[/tex] = $42

help please
Answer:
x<24
*the answer will be incorrect if you meant 2/(3x) instead of (2/3)x
Step-by-step explanation:
First, add 7 to both sides of the inequality to get "2/3x<16." Then multiply both sides by 3 to get "2x<48." Finally, divide both sides by 2 to get "x<24"

In the diagram below, AC intersects ABDE at B. Choose True or False for each statement
Answer:
false, true . false
Step-by-step explanation:
if u want an explanantion you can ask me :)
Answer: a. True b. True c. False
Explanation:
a. 65+25 =90 complementary angles add up to 90°
b. 65 + b + 25 = 180
90 + b = 180
b = 180 - 90
b = 90
Check-
65 + 25 + 90 = 180
90 + 90 = 180
180 = 180 ✅
c.not vertical angles because they aren’t across from eachother
In △ A B C , the measure of angle A is 103 ° and the measure of angle B is 37 ° . What is the measure of angle C ?
