Answer: x = 3

Step-by-step explanation:

if two triangles are congruent, that means thy have the same sides and angles.

6x + 8 = 9x - 1

-6x +1.    -6x +1

9 = 3x

divide both sides by 3 to get x by itself

x = 3

The anti-derivative of f(x) will be:

[tex]\int \:10x^4+12.5dx=2x^5+12.5x+C[/tex]

Step-by-step explanation:

Given the function

[tex]\:f\left(x\right)=10x^4\:+\:12.5[/tex]

Taking the anti-derivative of f(x)

[tex]\int \left(10x^4\:+\:12.5\right)\:dx\:[/tex]

[tex]\mathrm{Apply\:the\:Sum\:Rule}:\quad \int f\left(x\right)\pm g\left(x\right)dx=\int f\left(x\right)dx\pm \int g\left(x\right)dx[/tex]

[tex]\int \left(10x^4\:+\:12.5\right)\:dx\:=\int \:10x^4dx+\int \:12.5dx[/tex]

Solving

[tex]\int 10x^4dx[/tex]

[tex]\mathrm{Take\:the\:constant\:out}:\quad \int a\cdot f\left(x\right)dx=a\cdot \int f\left(x\right)dx[/tex]

[tex]=10\cdot \int \:x^4dx[/tex]

[tex]\mathrm{Apply\:the\:Power\:Rule}:\quad \int x^adx=\frac{x^{a+1}}{a+1},\:\quad \:a\ne -1[/tex]

[tex]=2x^5[/tex]

similarly,

[tex]\int 12.5dx[/tex]

[tex]\mathrm{Integral\:of\:a\:constant}:\quad \int adx=ax[/tex]

[tex]=12.5x[/tex]

so substituting these values

[tex]\int \left(10x^4\:+\:12.5\right)\:dx\:=\int \:10x^4dx+\int \:12.5dx[/tex]

                                [tex]=2x^5+12.5x[/tex]

                               [tex]=2x^5+12.5x+C[/tex]   ∵ Add constant to the solution

Therefore, the anti-derivative of f(x) will be:

[tex]\int \:10x^4+12.5dx=2x^5+12.5x+C[/tex]

The required correct answer is (a) x-intercept is (-8,0) and the y-intercept is (0,8).

In the context of a linear equation, an intercept is a point where the graph of the equation crosses or intersects with one of the axes in a coordinate system. There are two types of intercepts:

Here,
To find the x-intercept, we set y = 0 in the equation y = x + 8 and solve for x:

0 = x + 8

x = -8

Therefore, the x-intercept is (-8, 0).

To find the y-intercept, we set x = 0 in the equation y = x + 8 and solve for y:

y = 0 + 8

y = 8

Therefore, the y-intercept is (0, 8).

So the correct answer is (a) the x-intercept is (-8,0) and the y-intercept is (0,8).

Step-by-step explanation:

2.20

Answer:

Markdown is a reduction in the price of a product, made either by a commercial promotion, by a limited-time offer, by a discount due to a failure in the product, or any other situation that implies the realization of said reduction in the final price of the product for sale.

Thus, if the original price of the product is $282, and it has a markdown of 10%, to determine the discounted amount and the final price of the product, the following calculation must be made:

282 x 0.10 = X

28.2 = X

Thus, the discount on the original price is $ 28.20. Therefore, the final sale price will be $ 253.80 (since 282 - 28.20 is equal to that number).

Step-by-step explanation:

Step-by-step explanation:

The Taylor series expansion is:

Tₙ(x) = ∑ f⁽ⁿ⁾(a) (x − a)ⁿ / n!

f(x) = 1/x, a = 4, and n = 3.

First, find the derivatives.

f⁽⁰⁾(4) = 1/4

f⁽¹⁾(4) = -1/(4)² = -1/16

f⁽²⁾(4) = 2/(4)³ = 1/32

f⁽³⁾(4) = -6/(4)⁴ = -3/128

Therefore:

T₃(x) = 1/4 (x − 4)⁰ / 0! − 1/16 (x − 4)¹ / 1! + 1/32 (x − 4)² / 2! − 3/128 (x − 4)³ / 3!

T₃(x) = 1/4 − 1/16 (x − 4) + 1/64 (x − 4)² − 1/256 (x − 4)³

f(x) = 1/x has a vertical asymptote at x=0 and a horizontal asymptote at y=0.  So we can eliminate the top left option.  That leaves the other three options, where f(x) is the blue line.

Now we have to determine which green line is T₃(x).  The simplest way is to notice that f(x) and T₃(x) intersect at x=4 (which makes sense, since T₃(x) is the Taylor series centered at x=4).

The bottom right graph is the only correct option.

Answer:

150 degrees

Step-by-step explanation:

(Sorry, I know you don't want one but I posted this and then started editing it so hopefully you saw the answer already and I'm not delaying you or anything)

The interior of a quadrilateral always adds up to 360 degrees. y+80 = 180 degrees since they're on a straight line.

We have 3 angles: y = 100, 50, and 60.

360 - (100+50+60)

= 360 - 210

Answer:

64 people

Step-by-step explanation:

in the morning, 4 people are called. Those 4 people call 4 more people, which brings it to 16 people called. Those 16 people then each call 4 others, which is 16 x 4. Giving you the answer of 64 people for the evening.

FYI, if the question asked how many people were called in total, you would add the 4 people from the morning, 16 people from the afternoon, and 64 people in the evening to get a total of 84 people called.

Hope this helps!

This question is incomplete, the complete question is;

A 90% confidence interval for the mean height of a population is 65.7 < μ < 67.3

This result is based on a sample of size 169.

Construct a 99%confidence interval.

Answer: at 99%, confidence interval is [ 65.2, 67.8 ]

Step-by-step explanation:

Given that;

confidence level = 90%

∝ = 1 - 90% = 1 - 0.9 = 0.1

the mean height of a population is 65.7 < μ < 67.3

so

x" - t_∝/2, n-1{standard Error] = 65.7  ----let this be equation 1

x" + t_∝/2, n-1{standard Error] = 67.3 -----let this be equation 2

where t∝/2, n-1 = t_0.1/2, 169 - 1 = t_0.05, 168 = 1.654    (t table)

now we add equation one and equation two

2x" = 65.7 + 67.3 = 133

x" = 66.5

next we subtract equation one from equation two

(x" + t_∝/2, n-1{standard Error]) - (x" - t_∝/2, n-1{standard Error])

= 67.3 - 65.7 = 1.6

so

2 × t_∝/2,n-1 × standard Error  = 1.6

standard Error = 1.6 / (2 × t_∝/2,n-1)

we substitute

Standard Error = 1.6 / ( 2 × 1.654 ) = 1.6 / 3.308 = 0.48367

Now 99% confidence interval for μ is given as;

∝ = 1 - 0.99 = 0.01

x" ± t_∝/2, n-1{standard Error]

(x" ± t_0.01/2, 169-1 [standard Error])

where t_0.005, 168 = 2.6054  (t table)

now for Lower Bound: (x" - t_0.005, 168 [standard Error])

Lower Bound : ( 66.5 - (2.6054 × 0.48367))

= 66.5 - 1.26015 = 65.2398

Upper Bound : ( 66.5 + (2.6054 × 0.48367))

= 66.5 + 1.26015 = 67.7602

Therefore at 99%, confidence interval is [ 65.2, 67.8 ]

Answer:

y = 125x + 75

Step-by-step explanation:

Let x represents the week and

Let y represent the balance

When x = 2, y = 325.

This means

(x1,y1) = (2,325)

When x = 5, y = 700

This means

(x2,y2) = (5,700)

Required

Determine the equation

First, we need to solve for m, the slope

m = ∆y/∆x

i.e.

m = (y2 - y1)/(x2 - x1)

Substitute values for x and y

m = (700 - 325)/(5 - 2)

m = 375/3

m = 125

Next, we calculate the equation in slope intercept form using

y - y1 = m(x - x1)

Substitute values for m, x1 and y1

y - 325 = 125(x - 2)

y - 325 = 125x - 250

Collect like terms

y = 125x - 250 + 325

y = 125x + 75

Hence, the equation is:

y = 125x + 75

Answer: x=-125+950

Step-by-step explanation:

The value went from 700 to 325 in 3 weeks

700-325= 375 /3 =125

0=950

1=825

2=700

3=575

4=450
