The expression (Ux²+x-T) (2x-1) can be written in the form (2x-1)²(x+S) where U, T and S are constant. Find the values of U, T and S....... Please help me solve this polynomial
Answer:
U=2, S=1, T=1
Step-by-step explanation:
(Ux²+x-T) (2x-1)=(2x-1)²(x+S)
(Ux²+x-T)=(2x-1)(x+S)=2x²+(2S-1)x-S
U=2
2S-1=1 --> S=1
T=S=1

HELP ME PLS!! Here’s a picture that i uploaded for the question.
there is no picture :(
If x^(y)=5^(x-y) then dy/dx=
First, rewrite
[tex]x^y=e^{\ln x^y}=e^{y\ln x}[/tex]
[tex]5^{x-y}=e^{\ln5^{x-y}} = e^{\ln(5)(x-y)}[/tex]
Now, differentiate both sides using the chain rule:
[tex]\dfrac{\mathrm d\left(e^{y\ln x}\right)}{\mathrm dx}=\dfrac{\mathrm d\left(e^{\ln(5)(x-y)}\right)}{\mathrm dx}[/tex]
[tex]e^{y\ln x}\dfrac{\mathrm d(y\ln x)}{\mathrm dx}=e^{\ln(5)(x-y)}\dfrac{\mathrm d(\ln(5)(x-y))}{\mathrm dx}[/tex]
[tex]x^y\left(\dfrac{\mathrm dy}{\mathrm dx}\ln x+y\dfrac{\mathrm d(\ln x)}{\mathrm dx}\right)=\ln(5)5^{x-y}\left(\dfrac{\mathrm d(x)}{\mathrm dx}-\dfrac{\mathrm dy}{\mathrm dx}\right)[/tex]
[tex]x^y\left(\ln x\dfrac{\mathrm dy}{\mathrm dx}+\dfrac yx\right)=\ln(5)5^{x-y}\left(1-\dfrac{\mathrm dy}{\mathrm dx}\right)[/tex]
[tex]\left(x^y\ln x+\ln(5)5^{x-y}\right)\dfrac{\mathrm dy}{\mathrm dx}=\ln(5)5^{x-y}-yx^{y-1}[/tex]
[tex]\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\ln(5)5^{x-y}-yx^{y-1}}{x^y\ln x+\ln(5)5^{x-y}}[/tex]
Write the equation of a line that passes through the point (-2, 1) and has a slope of 4. A. y = 4x − 7 B. y = 4x + 1 C. y = 4x + 3 D. y = 4x + 9
Answer: D. y = 4x + 9
Step-by-step explanation:
Substitute the values of y and x from the given coordinate into the slope-intercept form using the given slope. Then solve for b
y = mx + b Given: Slope = 4 Coordinate (-2, 1)
1 = 4(-2) + b
1 = -8 + b add +8 to both sides, "cancels" -8 on right
1+ 8 = b
9 = b Rewrite equation using original slope and calculated b
y = 4x + 9

What is the perimeter, in units, of polygon EFGHJK?
Answer:
38 units.
Step-by-step explanation:
Perimeter of the polygon EFGHJK = 38 unit
What is perimeter?Perimeter of a shape is defined as the total length of its boundary. The perimeter of a shape is determined by adding the length of all the sides and edges enclosing the shape. It is measured in linear units of measurement like centimeters, meters, inches, or feet.
Given,
In graph of polygon EFGHJK
EF = 2 unit
FG = 10 unit
GH = 9 unit
HJ = 8 unit
JK = 7 unit
KE = 2 unit
Perimeter of EFGHJK = EF + FG + GH + HJ + JK + KE
= 2 + 10 + 9 + 8 + 7 + 2
= 38 unit
Hence, 38 unit is the measure of perimeter of polygon EFGHJK.

Given that BD is an angle bisector
Solve for m
Answer:
24 degrees
Step-by-step explanation:
since BD is an angle bisector, the given numbers are equal to each other
this means that you can write the equation as: 6x = x + 20
subtract x from both sides to move the variable to one side, this leaves you with: 5x = 20
then divide both sides by 5 to find x: x = 4
now substitute this into the value given for angle ABD: 6(4)
this gives you 24 degrees
divide 72 in ratio 3:4:5
The number who needs to be separated into a ratio = 72
Total number of parts = 3 + 4 + 5
= 12 parts
Each part = 72 ÷ 12
= 6
Then 3 parts = 3 × 6 = 18
4 parts = 4 × 6 = 24
5 parts = 5 × 6 = 30
Then , the ratio will be , 18 : 24 : 30
Therefore , 72 in the ratio 3:4:5 will be = 18 : 24 : 30 .

Complete Question
You want to test whether salaries for male doctors are different from salaries for female doctors, using a random sample of 100 male and 100 female doctors. The statistical test you should use is
a. t-Test: Two-Sample Assuming Equal Variances
b. t-Test: Two-Sample Assuming Unequal Variances
c. z-Test: Two Sample for Means
d. t-Test: Paired Two Sample for Means
Answer:
The correct option is C
Step-by-step explanation:
From the question we can see that
The salaries for male doctors is independent of The salaries for female doctors
Hence the samples obtained from both populations are independent
Also both of the random samples are sufficiently large.
So given that the samples are independent and sufficiently large then the best statistical test to use is z-Test: Two Sample for Means
