Answer:

R = [tex]\frac{U}{I}[/tex]

Step-by-step explanation:

Given

I = [tex]\frac{U}{R}[/tex] ( multiply both sides by R to clear the fraction )

R × I = U ( isolate R by dividing both sides by I )

R = [tex]\frac{U}{I}[/tex]

Answer:

331/100 or 3 31/100

Step-by-step explanation:

We have;

One - hundredth of 25 = 1/100 × 25 = 1/4

One-tenth of 30 = 1/10 × 30= 30/10 =3

One-thousandth of 60= 1/1000 × 60= 60/1000= 3/50

So we have:

1/4 + 3 + 3/50 = 331/100 or 3 31/100

Answer:

m = 1[tex]\frac{1}{7}[/tex], y = 1[tex]\frac{1}{7}[/tex]x + 10

Step-by-step explanation:

The equation of a line is y = mx + c where m is the slope and c is the y-intercept. I will be calculating the slope using the points (7, 2) and (0, 10)

m = [tex]\frac{rise}{run}[/tex]

   = [tex]\frac{2-10}{7-0}[/tex]

   = [tex]\frac{8}{7}[/tex]

   = 1[tex]\frac{1}{7}[/tex]

Based on the graph, the y-intercept is 10. Thus, the equation of the line is 1[tex]\frac{1}{7}[/tex]x + 10.

Answer:

Factored Form: f(x) = (x-7)(x-4)

Roots: x=7, x=4

Step-by-step explanation:

What  we can do here is break the given expression into groups;

x^2-11x+28 ---> break the expression into groups

(x^2-4x) +(-7x+ 28) ---> factor out x from x^2-4x

x(x-4) + (-7x +28) ---> factor - 7 from -7x +28

x(x-4) -7(x-4) ---> combine

(x-7)(x-4)

so if f(x) = (x-7)(x-4) then the roots would be x=7 and x=4

Final Answer: [tex]d = -\frac{1}{4}[/tex]

Steps/Reasons/Explanation:

Question: Equations with variables on both sides: decimals & fractions, [tex]6d - \frac{11}{2} = 2d - \frac{13}{2}[/tex].

Step 1: Subtract [tex]2d[/tex] from both sides.

[tex]6d - \frac{11}{2} - 2d = -\frac{13}{2}[/tex]

Step 2: Simplify [tex]6d - \frac{11}{2} - 2d[/tex] to [tex]4d - \frac{11}{2}[/tex].

[tex]4d - \frac{11}{2} = -\frac{13}{2}[/tex]

Step 3: Add [tex]\frac{11}{2}[/tex] to both sides.

[tex]4d = -\frac{13}{2} + \frac{11}{2}[/tex]

Step 4: Simplify [tex]-\frac{13}{2} + \frac{11}{2}[/tex] to [tex]-1[/tex].

[tex]4d = -1[/tex]

Step 5: Divide both sides by [tex]4[/tex].

[tex]d = -\frac{1}{4}[/tex]

Answer:

The missing dimension of the prism is (x-4)

Step-by-step explanation:

Here, we want to find the missing dimensions of the prism

To get the volume, we are to multiply three dimensions since we are talking about volume

Mathematically, to find the third dimension, we need to divide the original polynomial by the product of the two other dimensions

The product of the two other dimensions is;

(x-1)(x-9) = x^2-9x-x + 9

= x^2-10x+ 9

So we divide;

(x^3-14x^2+49x-36)/(x^2-10x+ 9)

We can use long division to get this

using long division, the answer here is x-4

The volume of a prism is the product of its dimensions.

The missing dimension of the prism is x - 4

The volume function is given as:

[tex]\mathbf{V(x) = x^3 - 14x^2 + 49x - 36}[/tex]

Let the missing dimension of the prism be y.

So, the volume is calculated using:

[tex]\mathbf{V(x) = y \times (x - 9) \times (x -1)}[/tex]

Multiply the factors

[tex]\mathbf{V(x) = y \times ( x^2-9x-x + 9)}[/tex]

[tex]\mathbf{V(x) = y \times ( x^2-10x + 9)}[/tex]

Equate both expressions of volume

[tex]\mathbf{y \times ( x^2-10x + 9) = x^3 - 14x^2 + 49x - 36}[/tex]

Make y the subject

[tex]\mathbf{y = \frac{x^3 - 14x^2 + 49x - 36}{x^2-10x + 9 }}[/tex]

Factor the numerator

[tex]\mathbf{y = \frac{(x - 4)(x^2-10x + 9 )}{x^2-10x + 9 }}[/tex]

Cancel out common factors

[tex]\mathbf{y = x - 4}[/tex]

Hence, the missing dimension of the prism is x - 4

Answer:

26.55°C

Step-by-step explanation:

21.85 + 4.7

Average maximum daily temperature = 21.85°C

Average minimum temperature = - 4.7°C

The average daily maximum temperature is x°C higher than the average daily minimum temperature ;

x = (maximum temperature - minimum temperature)

x = (21.85 - (-4.7))°C

x = (21.85 + 4.7)°C

x = 26.55°C

Hence, The average daily maximum temperature is 26.55°C higher than the average daily minimum temperature

Answer:  x > -9     and x [tex]\leq[/tex] -1

Step-by-step explanation:

-5 < x + 4[tex]\leq[/tex] 3   To solve the inequality, subtract 4 from both sides or u can divide the whole thing into two inequalities like, -5 < x + 4    and x + 4 [tex]\leq[/tex] 3  and solve for each other.

-5 < x + 4 [tex]\leq[/tex] 3

-4         -4    -4
