Answer:

A. (3,2)

Step-by-step explanation:

The vertex is the point where the axis of symmetry crosses -- in this case, our vertex is a maximum -- since a value, or rate of change, is negative.

Hi! please help! thank you

Answer:

1) p≥2

2) e-9=13

3) f<5

Step-by-step explanation:

1) If there are at least two slices left, there could be more, so use p≥2, meaning p is greater than or equal to 2.

2) e is your starting amount, so put that first, then it says it decreases by 9, so it is e-9=13.

3) If there are fewer than 5, it can not be 5 so you use <.

f<5 or gallons is less than 5.

∆ABC m∠B = 90° AB = 4 BC = 3 Find AC

lutik1710 [3]

Step-by-step explanation:

In ∆ABC, m∠B = 90°

Therefore ∆ABC is a right angled triangle with sides AB = 4 & BC = 3. AC is the hypotenuse.

Hence, by Pythagoras theorem:

$AC^2 = AB^2 +BC^2 \\ \\ \therefore \: AC = \sqrt{AB^2 +BC^2 } \\ = \sqrt{ {4}^{2} + {3}^{2} } \\ = \sqrt{16 + 9} \\ = \sqrt{25} \\ = 5 \\ \\ \huge \red{ \boxed{ \therefore \: AC = 5 \: units}}$

Question 11 Find the value of y. X+ 13 45° No links please! Thanks for the help!

9966 [12]

Answer:

First option: $13 \sqrt{2}$

Step-by-step explanation:

$cosθ = \frac{adj}{hyp}$

$cos45° = \frac{13}{y}$

Multiply both sides by y:

$y(cos45°) = 13$

$y ( \frac{ \sqrt{2} }{2} ) = 13$

$y = 13 \div \frac{ \sqrt{2} }{2}$

$y = 13 \times \frac{2}{ \sqrt{2} }$

$y = \frac{26}{ \sqrt{2} } ( \frac{ \sqrt{2} }{ \sqrt{2} } )$

$y = \frac{26 \sqrt{2} }{2}$

$y = 13 \sqrt{2}$
