I am not sure how the answer is coming up as an "m+1+ or "m-1" I am a ... Factor: : 4m^2 -18m + 14. We can simplify this, factor out 2 2(2m^2 - 9m + 7) ... FOIL (5m+3)(m+1) : 15m^2 - 10m - 25. Factor out 5 5(3m^2 - 2m - 5) Factors to 3(3m - 5)(m + 1) FOIL this to confirm it : 50m^3 - 2m. Simplify, factor out 2m 2m(25m^2 - 1)

Find a standardized test statistic and use the t-distribution to find the p-value and make a conclusion using a 5% significance

Ne4ueva [31]

Answer:

1 μ = M μ ≠ M 2

2 μ > M μ < M 1

3 μ < M μ > M 1

If we use a 5% significance level, the p-value of 0.165 is not less than α = 0.05 so we would not

How do I solve this?

KengaRu [80]

Answer with Step-by-step explanation:

The given differential euation is

$\frac{dy}{dx}=(y-5)(y+5)\\\\\frac{dy}{(y-5)(y+5)}=dx\\\\(\frac{A}{y-5}+\frac{B}{y+5})dy=dx\\\\\frac{1}{100}\cdot (\frac{10}{y-5}-\frac{10}{y+5})dy=dx\\\\\frac{1}{100}\cdot \int (\frac{10}{y-5}-\frac{10}{y+5})dy=\int dx\\\\10[ln(y-5)-ln(y+5)]=100x+10c\\\\ln(\frac{y-5}{y+5})=10x+c\\\\\frac{y-5}{y+5}=ke^{10x}$

where

'k' is constant of integration whose value is obtained by the given condition that y(2)=0\\

$\frac{0-5}{0+5}=ke^{20}\\\\k=\frac{-1}{e^{20}}\\\\\therefore k=-e^{-20}$

Thus the solution of the differential becomes

$\frac{y-5}{y+5}=e^{10x-20}$

Each side of a square is increasing at a rate of 5 cm/s. At what rate is the area of the square increasing when the area of the

icang [17]

Answer:

Step-by-step explanation:

Area of a square with side of length L is expressed as A = L². The rate at which the area is increasing will be expressed as dA/dt.

dA/dt = dA/dL * dL/dt where

dL/dt is the rate at which each side of the square is increasing.

Since dA/dL = 2L, dA/dt = 2L dL/dt

Given dL/dt = 5cm/s and the Area of the square = 49 cm²

49 = L²

L = √49

L = 7cm

dA/dt = 2(7) * 5

dA/dt = 14*5

dA/dt = 70cm/s

The rate at which the area of the square is increasing is 70cm/s

ABC and XYZ are similar. Find the missing side length.

valina [46]

Answer:

Step-by-step explanation:

The easiest way to solve this is by cross multiplying. We can make an equation to find the answer of this by simply taking a side from each triangle and then the variable and equal side on the other triangle, shown below.

$let \: \: ? = x$

$\frac{7}{49} = \frac{8}{x}$

Now we solve with cross multiplication

$7 x = 392 \\ x = 56$

Now we know the mystery number is 56
