Answer:

$422.80

Step-by-step explanation:

Answer: $428.09

Step-by-step explanation:

First let's add all the hours Sanjay worked;

37 + 3.5 = 40.5 total hours worked.

Now multiply the amount of hours he worked by $10.57.

40.5 x 10.57 = $428.09 of total pay.

Answer:

64 feet

Step-by-step explanation:

Complete question

A ball is thrown straight up with initial velocity of 64 ft./s. The height of the ball t seconds after it is thrown is given by the formula s(t)=64t-16t^2. Find the maximum height reached by the ball.

At maximum height, the velocity of the ball is zero, i.e ds/dt  =0

ds/dt = 64 - 32t

64 - 32t = 0

32t = 64

t = 64/32

t = 2secs

Substitute t = 2secs into the given equation;

Recall that s(t)=64t-16t^2

s(2) = 64(2) - 16(2)^2

s(2) = 128 - 16(4)

s(2) = 128 - 64

s(2) = 64 ft

Hence the maximum height reached by the ball is 64 feet

Answer:

$5400

$45

Step-by-step explanation:

Interest = principal x interest rate x time

principal = p

interest rate = 15%

time = 20/365 = 0.054795

Interest = 5445 - p

5445 - p = 0.15 x p x  0.054795

5445 - p = 0.008219p

Collect like terms and solve for p

p = $5400

Interest = 5445 - 5400 = $45

Answer:

1.46035

2.200

3. 236

Step-by-step explanation:

1. Formula: length x width x height

23x9x5=46035

2. Formula: triangle area (base x height / 2) x length

10 x 20 = 200

3. Formula: πr^2 x height

(5/2)^2 x 3.14 x 12 = 235.5 = 236

Answer and step-by-step explanation:

1. A=734

due to this stuff A=2(wl+hl+hw)=2·(9·23+5·23+5·9)=734

3. A≈227.77

due to this A=2πrh+2πr2=2·π·2.5·12+2·π·2.52≈227.76547

Answer:

2n^2

Step-by-step explanation:

The greatest common factor (GCF) in a polynomial is the factor by which all the terms in the polynomial can be divided. In order to find this factor, you need to completely factor both terms in the polynomial and then note down which ones they have in common:

Step 1: 4n^3 + 6n^2 (Given polynomial)

Step 2: 2*2*n*n*n + 2*3*n*n (Factor the polynomial)

Step 3: 2*2*n*n*n + 2*3*n*n (Identify shared factors)

Step 4: 2*n*n = 2n^2; the GCF is 2n^2 (Multiply the shared factors by each other to get the GCF)

The greatest common factor of the above polynomial is [tex]2n^{2}[/tex].

We have a polynomial as -

[tex]4n^{3} +6n^{2}[/tex]

We have to find out the greatest common factor of this polynomial.

The greatest factor is the largest number that is the factor of two or more numbers.

We have the following polynomial -

f(n) = [tex]4n^{3} +6n^{2}[/tex]

We can write the function as -

f(n) = [tex]f_{1}(n) +f_{2}(n)[/tex]

In order to find the greatest common factor, take out all the common terms from the individual functions [tex]f_{1}(n)[/tex] and [tex]f_{2}(n)[/tex].

Therefore, we can write the above function f(n) as -

f(n) =  [tex]2n\times2n^{2} + 2n^{2}\times3 \;\;= \;\;2n^{2} (2n +3)[/tex]

Hence, the greatest common factor of the above polynomial is [tex]2n^{2}[/tex].

Step-by-step explanation:

Explanation:

Given:

−3x2+12x+1=0

This is in the form:

ax2+bx+c=0

with a=−3, b=12 and c=1

In order to decide which method to use, we can first examine the discriminant:

Δ=b2−4ac=122−4(−3)(1)=144+12=156

Since Δ>0 we can tell that the quadratic has 2 distinct real solutions, but because it is not a perfect square we can also tell that those solutions are irrational.

So there is no rational factorisation and we can discount the use of an AC method or similar.

We can use the quadratic formula or we can complete the square.

If we choose to use the quadratic formula, then we find:

x=−b±√b2−4ac2a

x=−b±√Δ2a

x=−(12)±√1562(−3)

x=−12±2√39−6

x=2±√393

When completing the square, note that b=12 is already divisible by a=−3 and by
