Use a definite integral to find the area under the curve between the given x-values. f(x) = 3 x from x = 1 to x = 8

Answers

Answer 1

Answer: 94.5

Step-by-step explanation:

Given

Function is [tex]f(x)=3x[/tex] and the boundary is [tex]x=1\ \text{to}\ x=8[/tex]

Integrating the function

[tex]\Rightarrow I=\int_{1}^{8}f(x)dx\\\\\Rightarrow I=\int_{1}^{8}3xdx\\\\\Rightarrow I=\left ( \frac{3x^2}{2} \right )_1^8\\\Rightarrow I=1.5(8^2-1^2)=1.5(64-1)\\\Rightarrow I=94.5[/tex]

The value of integral is 94.5

Step-by-step explanation:

John drank 12 oz of soda. If this was 60% of the soda in the bottle, how many ounces of soda were in the full bottle?

Answers

Answer:

20oz

Step-by-step explanation:

60%=12oz

this can be simplified into 1%

in order to find 1% divide by 60

60%/60=1%

in order to find out how much 1% is, divide 12oz by the number used to divide the percent

12/60=0.2

so 0.2=1% and we want to know 100% so multiply by 100

0.2x100=20

1%x100=100%

so 20oz=100% of the bottle

Simplify (4a^m+3)^3*(1/16a^1-m)^2

Answers

The simplified answer is 27m^2

The simplification of the given expression is equal to (336a² + 27[tex]a^{(2-2m)[/tex])/256.

To simplify the expression, let's start by expanding each term and then combining like terms:

Expand the first term (4[tex]a^m[/tex] + 3)³

(4[tex]a^m[/tex] + 3)³ = (4[tex]a^m[/tex]  + 3)(4[tex]a^m[/tex] + 3)(4[tex]a^m[/tex]  + 3)

Using the binomial expansion formula for (a + b)³

(a + b)³ = a³ + 3a²b + 3ab² + b³

So, for (4[tex]a^m[/tex]  + 3)³

(4[tex]a^m[/tex]  + 3)³ = 4³ × ([tex]a^m[/tex] )³ + 3 ×4² [tex]a^m[/tex]  ([tex]a^m[/tex] )²× 3 + 3 × 4× ([tex]a^m[/tex] ) × 3² + 3³

= 64[tex]a^{(3m)[/tex] + 144[tex]a^{(2m)[/tex] + 108[tex]a^m[/tex] + 27

Expand the second term (1/16[tex]a^{(1-m)[/tex])²

(1/16[tex]a^{(1-m)[/tex])² = (1/16[tex]a^{(1-m)[/tex]) (1/16[tex]a^{(1-m)[/tex])

Simplify the square of a fraction by squaring the numerator and denominator separately:

(1/16[tex]a^{(1-m)[/tex])² = (1²)/(16²) × ([tex]a^{(1-m)[/tex])²

= 1/(256) × [tex]a^{(2(1-m))[/tex]

=[tex]a^{(2-2m)[/tex]/256

Now, let's multiply both simplified terms:

(4[tex]a^m[/tex] + 3)³ ×(1/16[tex]a^{(1-m)[/tex])²

= (64[tex]a^{(3m)[/tex] + 144[tex]a^{(2m)[/tex]+ 108[tex]a^m[/tex]+ 27)  ([tex]a^{(2-2m)[/tex]/256)

Now, combine the terms with similar exponents:

= (64[tex]a^{(3m)[/tex]  [tex]a^{(2-2m)[/tex] + 144[tex]a^{(2m)[/tex] [tex]a^{(2-2m)[/tex]+ 108[tex]a^m[/tex]  [tex]a^{(2-2m)[/tex] + 27 × [tex]a^{(2-2m)[/tex])/256

Using the property [tex]a^m \times a^n = a^{(m+n):[/tex]

= (64[tex]a^{(3m + 2 - 2m)[/tex]+ 144[tex]a^{(2m + 2 - 2m)[/tex] + 108[tex]a^{(m + 2 - 2m)[/tex]+ 27[tex]a^{(2-2m)[/tex])/256

Simplify the exponents,

= (64a² + 144a² + 108a² + 27[tex]a^{(2-2m)[/tex])/256

Now, combine the like terms:

= (336a² + 27[tex]a^{(2-2m)[/tex])/256

Therefore,  the simplified expression is equal to (336a² + 27[tex]a^{(2-2m)[/tex])/256.

if y=27 when x= 8 find y when x =11

Answers

Answer:

37 1/8

Step-by-step explanation:

The problem probably assumes direct variation

y=kx

IF so, then plug in the values and solve for k

27=k(8)

k = 27/8

y= (27/8)x.  Now let x = 11

y = (27/8)11 = 27(11)/8 = 37.125 = 37 1/8

y = 37 1/8

the problem is making some assumption about the relation between x and y.  The simplest assumption that's likely is direct variation,  that x and y are linearly related.  The graph is a straight line through the origin with slope = 27/8
