Step-by-step explanation:

The question is incomplete as Micah's workings is not attached. So, there's no way to determine where Micah's error is.

However, I'll solve for the vertex of the given function.

Given

[tex]y = -9.5x^2 + 47.5x + 63[/tex]

Vertex, V is of the form:

[tex]V= (h,k)[/tex]

Where

[tex]h = -\frac{b}{2a}[/tex]

and

[tex]k = f(h)[/tex]

Solving for h:

[tex]y = -9.5x^2 + 47.5x + 63[/tex]

[tex]y = ax^2 + bx + c[/tex]

So:

[tex]a = -9.5[/tex]

[tex]b = 47.5[/tex]

[tex]c = 63[/tex]

[tex]h = -\frac{b}{2a}[/tex]

[tex]h = -\frac{47.5}{2 * -9.5}[/tex]

[tex]h = -\frac{47.5}{-19}[/tex]

[tex]h = \frac{47.5}{19}[/tex]

[tex]h = 2.5[/tex]

Solving for k

[tex]k = f(h)[/tex]

[tex]k = f(2.5)[/tex]

Substitute 2.5 for x in [tex]y = -9.5x^2 + 47.5x + 63[/tex]

[tex]k = -9.5 * 2.5^2 + 47.5* 2.5 + 63[/tex]

[tex]k = -59.375+ 118.75 + 63[/tex]

[tex]k = 122.375[/tex]

Hence:

The vertex is

[tex]V = (2.5,122.375)[/tex]

Answer:

if ur doing savvas

Step-by-step explanation:

answer for the first one is:
Micah used the wrong sign for b in the formula x=-b/2a

answer for the second one is:
vertex is = (-2.5, 122.375)

PART A: 2.25

PART B: 14

Answer:

[tex]g^{-1}[/tex] (x) = 8x + 48

Step-by-step explanation:

let y = g(x) and rearrange making x the subject, that is

y = [tex]\frac{x}{8}[/tex] - 6 ( add 6 to both sides )

y + 6 = [tex]\frac{x}{8}[/tex] ( multiply both sides by 8 )

8(y + 6) = x , distribute

8y + 48 = x

Change y back into terms of x with x = [tex]g^{-1}[/tex] (x) , thus

[tex]g^{-1}[/tex] (x) = 8x + 48

Step-by-step explanation:

Raia’s monthly car payments is $8160.

Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.

Given that, Raia purchases a new car for $32,000 and finances it with a 6-year simple interest loan at a rate of 4.25%

We need to find;

What are Raia’s monthly car payments?

So, SI = PRT / 100

P = Principal amount

r = rate

T = time

So,

SI = 32000 x 4.25 x 6 / 100

= 8160

Hence, Raia’s monthly car payments is $8160.

Answer:

1. [tex]Dexter = 11:5[/tex]  [tex]Lena = 9:4[/tex]

2. [tex]Dexter = \frac{11}{5}[/tex]  [tex]Lena = \frac{9}{4}[/tex]

3. [tex]Dexter = \frac{44}{20}[/tex]   [tex]Lena = \frac{45}{20}[/tex]

4. [tex]\frac{45}{20} > \frac{44}{20}[/tex]

Step-by-step explanation:

Given

Dexter

[tex]Science\ Fiction = 11[/tex]

[tex]History = 5[/tex]

Lena

[tex]Science\ Fiction = 9[/tex]

[tex]History = 4[/tex]

Solving (1): Write as ratio

Represent Science Fiction with S and History with H

For Dexter;

[tex]Ratio = S : H[/tex]

[tex]Dexter = 11:5[/tex]

[tex]Lena = 9:4[/tex]

Solving (2): Write ratio as fraction

[tex]Fraction = \frac{S}{H}[/tex]

[tex]Dexter = \frac{11}{5}[/tex]

[tex]Lena = \frac{9}{4}[/tex]

Solving (3): Write as a common denominator

[tex]Dexter = \frac{11}{5}[/tex]

Multiply by [tex]\frac{4}{4}[/tex]

[tex]Dexter = \frac{11}{5} * \frac{4}{4}[/tex]

[tex]Dexter = \frac{44}{20}[/tex]

[tex]Lena = \frac{9}{4}[/tex]

Multiply by [tex]\frac{5}{5}[/tex]

[tex]Lena = \frac{9}{4} * \frac{5}{5}[/tex]

[tex]Lena = \frac{45}{20}[/tex]

Solving (4): Compare both fractions

By comparison;

[tex]\frac{45}{20}[/tex] is greater than [tex]\frac{44}{20}[/tex]

So, we have:

[tex]\frac{45}{20} > \frac{44}{20}[/tex]

Answer:

25 [tex]\frac{5}{11}[/tex]

Step-by-step explanation:

This is the answer because:

1) You have to convert 3 [tex]\frac{7}{11}[/tex] to an improper fraction. You can do this by multiplying 11 and 3 (the denominator and the whole number) then add 7 (the numerator). This equals to [tex]\frac{40}{11}[/tex].

2)  [tex]\frac{40}{11}[/tex] x [tex]\frac{7}{1}[/tex] = [tex]\frac{280}{11}[/tex]

3) Finally. convert [tex]\frac{280}{11}[/tex] to an mixed fraction which is 25 [tex]\frac{5}{11}[/tex]

Therefore, the answer is 25 [tex]\frac{5}{11}[/tex]

4/5

Step-by-step explanation:

{(2/5) / (1/2)} ×1

= (2/5)÷(1/2)

= 2/5×2/1

= 4/5

Answer:

4/5

Step-by-step explanation:

Because if it can eat 2/5's in 1/2 hours, then if it eats for 1 whole hour or 2/2's it will be able to eat 4/5's of it's own body weight.

Just imagine that one half hour is 1 and if you add two half hours together it makes one complete hour or 2/2. So just multiply it by 2 cause it was eating for two half hours.

Given function to us is : ⅚ x + 1 .

Here is step by step explanation :

Step 1 : Replace h(x) with y .

The equation becomes ,

⇒ y = ⅚x + 1 .

Step 2 : Interchange the variables .

⇒ x = ⅚y + 1.

Step 3 : Solve for y .

⇒x = ⅚ y + 1.

⇒ x - 1 = ⅚y .

⇒ y = 6/5 ( x - 1 )

⇒ y = 6/5x - 6/5 .

Answer:

[tex]E=3.97\times 10^{-27}\ \text{ergs}[/tex]

Step-by-step explanation:

It is given that,

The sun produces [tex]3.9\times 10^{33}\ \text{ergs}[/tex] of radiant energy per second.

We need to find how many ergs of radiant energy does the sun produce in [tex]1.55\times 10^7\ s[/tex].

Energy produced in 1 seconds = [tex]\dfrac{1}{3.9\times 10^{33}}\ \text{ergs}[/tex]

In [tex]1.55\times 10^7\ s[/tex], energy produced is :

[tex]E=\dfrac{1}{3.9\times 10^{33}}\times 1.55\times 10^7\ \text{ergs}\\\\=3.97\times 10^{-27}\ \text{ergs}[/tex]

Hence, the radiant energy produced in 1 second is [tex]3.97\times 10^{-27}\ \text{ergs}[/tex].

Answer:

Part A: It is given that,

The sun produces 3.9x10^33 ergs of radiant energy per second.

We need to find how many ergs of radiant energy does the sun produce in 1.55 x 10^7 s

Energy produced in 1 seconds =  1/3.9 x 10^33 ergs

In 1.55 x 10^7 s energy produced is : E=3.9/10^33 x 1.55 x 10^7 ergs

= 3.97 x 10^-27 ergs  

In conclusion the radiant energy radiated per second 3.97 x 10^27 ergs

Answer:

149

Step-by-step explanation:

There is a common difference between consecutive terms in the sequence.

5 - 2 = 8 - 5 = 11 - 8 = 14 - 11 = 3

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = 3 , thus

a₅₀ = 2 + (49 × 3) = 2 + 147 = 149
