Answer:

Step-by-step explanation:

The vertex is (d, e)

for quadratic function: f(x) = ax² + bx + c we have:

d = -b/a and d = (x₁ + x₂)/2

a = 1, b = k, x₁ = -4, x₂=-2

so:

d = -b/a = -k/1 = -k and d = (x₁ + x₂)/2 = (-4-2)/2 = -3

-k = -3

k = 3

Answer:

$a_{n}$ = 20n + 12

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 52 - 32 = 72 - 52 = 92 - 72 = 20

This indicates the sequence is arithmetic with explicit formula

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 32 and d = 20, thus

$a_{n}$ = 32 + 20(n - 1) = 32 + 20n - 20 = 20n + 12

Answer:

4.58258

Step-by-step explanation:

Pythagorean Theorem:

a² + b² = c²

Input:

2² + x² = 5²

Remember, c² is always the side opposite of the right angle...

4 + x² = 25

21 = x²

x = 4.58258

What is the input if the output is 0 ?

Elodia [21]

In other words, what is y if x is 0.

Look on the graph, a line passes through point, $A(x,y)\longrightarrow A(0,-3)$

So we can conclude that at that very point the input x was 0 and the output y was -3 therefore,

$\boxed{f(-3)=0}$

Hope this helps.

Find the measure of the indicated angle. Please can you help? I need to show work.

777dan777 [17]

Answer:

64°

Step-by-step explanation:

∠RQP = 46°

∠PRQ = 180° - 110° = 70°

∠PRQ + ∠RQP + ∠RPQ = 180°

70° + 46 + ∠RPQ = 180°

116° + ∠RPQ = 180°

Find ∠RPQ

∠RPQ = 180° - 116° = 64°
