answer:

7.81

Step-by-step explanation:

ohh i like these questions this is the pythagorean theorem

1) a2+b2=c2

2) 5(2)+6(2)=c2

3) 25+36=c2

4) 61=c2

5) sqr root it

6) 7.81

Here are the senteces:

If those two were both the legs they would give us the answer of 7.81

gives us only two options of answers and the other choice is putting

one of those options as a hypotenuse.So our chance for the third side

being 7.81 is 50% chance.

have a good day

syeda has finished 20% of her math assignment. The assignment includes 50 problems how many problems has syeda completed?

Nostrana [21]

Answer:

10 problems

Step-by-step explanation:

This is the answer because:

1) We have to solve for what 20% of 50 is since she finished 20% of her test:

20% of 50 = 10

$\frac{2}{10}$ × $\frac{50}{1}$ = $\frac{100}{10}$ = 10

Therefore, the answer is 10 problems.

Hope this helps! :D

can anyone help on these two questions show your work and explain please 5. the table below shows the temperature T(m) of a cup

andreyandreev [35.5K]

Answer:

(1), (3)

Step-by-step explanation:

5. If m starts at 1, a geometric series has the form a₁ (r)ᵐ⁻¹.

If m starts at 0, a geometric series has the form a₀ (r)ᵐ.

Here, m starts at 0. The first term, a₀, is 150. The temperature is decreasing, so we're looking for an r < 1. Therefore, the answer must be (1) 150 (0.85)ᵐ.

7. A quadratic written in vertex form is:

y = a(x - h)² + k

We can find the vertex of the parabola using x = -b/(2a).

x = -12 / (2*3)

x = -2

f(-2) = 3(-2)² + 12(-2) + 11

f(-2) = -1

So the vertex (h, k) is at (-2, -1).

Therefore, the answer must be f(x) = 3(x + 2)² - 1

We can also show this by completing the square.

f(x) = 3x² + 12x + 11

f(x) = 3(x² + 4x) + 11

f(x) = 3(x² + 4x + 4) - 3(4) + 11

f(x) = 3(x + 2)² - 1

Answer all the questions, just the answers, it's pythagorean theorem, plssss helpppp

Gre4nikov [31]

Answer:

1. option c

2. option b

3. option b

Step-by-step explanation:

1 . option C

Square of longer side = sum of squares of other side

5, 6 , 11

$121 = 25 + 36\\does\ not \ satisfy$

9, 12, 16

$256 = 144 + 81\\Does\ not \ satisfy$

7, 24, 25

$625 = 576 + 49\\Does\ satisfy$

12, 20, 25

$625 = 400 + 144\\does \ not \ satisfy$

2. Option B

Square of longer side = sum of squares of other side

15 ² = 8 ² + r²

225 = 64 + r²

161 = r²

r = 12.688

r = 13ft

3 . Option b

To find length of AB, Use distance formula

$AB = \sqrt{(x_2- x_1)^2 + (y_2 - y_1)^2}$

$= \sqrt{(14-3)^2 + (6-1)^2}\\\\=\sqrt{11^2 + 5^2}\\\\=\sqrt{121 + 25}\\\\= \sqrt{146} \\= 12 \ ft$
