Answer:

26

Step-by-step explanation:

Answer:

26

Step-by-step explanation:

Step 1:

Start by setting it up with the divisor 3 on the left side and the dividend 78 on the right side like this:

   3 ⟌ 7 8  

Step 2:

The divisor (3) goes into the first digit of the dividend (7), 2 time(s). Therefore, put 2 on top:

       2    

   3 ⟌ 7 8  

Step 3:

Multiply the divisor by the result in the previous step (3 x 2 = 6) and write that answer below the dividend.

       2    

   3 ⟌ 7 8  

       6    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (7 - 6 = 1) and write the answer below.

       2    

   3 ⟌ 7 8  

     - 6    

       1    

Step 5:

Move down the 2nd digit of the dividend (8) like this:

       2    

   3 ⟌ 7 8  

     - 6    

       1 8  

Step 6:

The divisor (3) goes into the bottom number (18), 6 time(s). Therefore, put 6 on top:

       2 6  

   3 ⟌ 7 8  

     - 6    

       1 8  

Step 7:

Multiply the divisor by the result in the previous step (3 x 6 = 18) and write that answer at the bottom:

       2 6  

   3 ⟌ 7 8  

     - 6    

       1 8  

      1 8  

Step 8:

Subtract the result in the previous step from the number written above it. (18 - 18 = 0) and write the answer at the bottom.

       2 6  

   3 ⟌ 7 8  

     - 6    

       1 8  

     - 1 8  

         0  

Answer:it may be the first one but I can’t see the lines on the graph clearly.

Step-by-step explanation:

2z² + z + C = A (z + 1)² + B (z + 1) + 4

Expand the right side completely and collect terms with the same power of z :

2z² + z + C = A (z² + 2z + 1) + B (z + 1) + 4

2z² + z + C = Az² + 2Az + A + Bz + B + 4

2z² + z + C = Az² + (2A + B)z + A + B + 4

Now match up terms on either side that have the same power of z. This gives

2 = A ................. (2nd power)

1 = 2A + B ......... (1st power)

C = A + B + 4 .... (0th power)

Solve for A, B, and C. The first equation gives A = 2 right away, so in the second equation we get

1 = 2*2 + B

B = -3

and in the third equation we get

C = 2 + (-3) + 4

C = 3

Answer:

15 3/4

Step-by-step explanation:

8+7=15

1/2+1/4= 3/4

15+3/4

Answer:

15 3/4

Step-by-step explanation:

You need to have like denominators before you add so you need to find the LCM (least common multiple) of the two numbers. Then you have to find how much you have to multiply each number by to get the multiple. Then you just have to remember that whatever you do to the bottom you do to the top.

1. 8 1/2 + 7 1/4     This is your equation.

2. 8 2/4 + 7 1/4      The LCM of 2 and 4 is 4. You multiply by two in the bottom to get 4 so you multiply by 2 at the top. (This is talking about the first fraction).

3. 15 3/4    Then you just add as you would normally add without changing the denominators an simplifying if you need to. (You don't need to simplify for this equation).

I hope this helped you.

f(-7) = 21

Answer:

The prize is p100,000.00, and we can define this as the 100%.

Now, we could say:

"Each member receives the same percentage of the price as the total percentage of the project that he/she did"

Then:

Member A did 25% of the total project.

Then he gets an amount X.

X = 25%

p100,000.00 = 100%

We can solve this system for X as:

X = (25%/100%)*p100,000.00 = p25,000.00

Now we can use the samme aproach for the other members:

Member B did 40% of the total project:

Then he gets an amount X.

X = 40%

p100,000.00 = 100%

X = (40%/100%)*p100,000.00 = p40,000.00

Member C did 25% of the total project.

Then he gets an amount X.

X = 25%

p100,000.00 = 100%

X = (25%/100%)*p100,000.00 = p25,000.00

Member D did 10% of the total project.

Then he gets an amount X.

X = 10%

p100,000.00 = 100%

X = (10%/100%)*p100,000.00 = p10,000.00

Now, we also could divide the price evenly between the four members:

p100,000.00/4 = p25,000.00

So they all get the same amount, but i think that the actual solution to this problem is the other one.

Answer:

Definamos:

A = Ancho

L = Largo.

Sabemos que el área es rectangular, y para un rectángulo de ancho A y largo L, el área es:

Área = A*L.

Y sabemos que L = 2*A.

a) Una imagen se encuentra abajo.

b) Como podemos escribir la variable L en términos de la variable A, podemos escribir:

Área = A*L = A*(2*A) = 2*A^2

Entonces la variable que usamos es el ancho.  

Ahora podemos resolver el problema:

52m^2 = 2*A^2

52m^2/2 = 26m^2 = A^2

A = √(26m^2) = 5.1 m

Entonces el largo es:

L = 2*A = 2*5.1m = 10.2 m

b=-8

Step-by-step explanation:

Sorry I don't have time to show work right now and write it down but this is the answer.

Answer:

b=8

Step-by-step explanation:

1.1     Pull out like factors :

-8 - b  =   -1 • (b + 8)  

Solving a Single Variable Equation

2.1      Solve  :    -b-8 = 0  

Add  8  to both sides of the equation :  

                     -b = 8

Multiply both sides of the equation by (-1) :  b = -8

The required simplified form of the expression 1/2 x 3/5 x 4/9 is 12/90.

Given that, to determine the simplified form of the expression 1/2 x 3/5 x 4/9.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
= 1/2 x 3/5 x 4/9
Simplifying,
= [1×3×4] / [2×5×9]

= [12]/[90]
= 12 / 90

Thus, the required simplified form of the expression 1/2 x 3/5 x 4/9 is 12/90.

Answer:

Step-by-step explanation:

The x-term has even degree so is never negative. The x-term is subtracted from 12, so the maximum value of the function will be found where x=0. That value is 12 -0 = 12.

  f(0) = 12 . . . . absolute maximum

Answer:

The function [tex]f(x)=12-6x^4[/tex] has an absolute maximum value of [tex]12[/tex] and this occurs at [tex]x $\ equals 0.[/tex]

Step-by-step explanation:

The maximum value of this function is at 12, because if you rewrite this function:

The +12 is the k-value (the graph of this function is a parabola) of the vertex form of a quadratic. Just a reminder:

Vertex form of a parabola:

You can see the 12 is the k-value. The k-value of the vertex form is the vertical shift of the parabola, meaning that this parabola is shifted 12 units upwards.

Since the parabola opens down (you can tell by the negative a-value [tex]-6[/tex]), there is a maximum value at the k-value, i.e. the vertical shift.

[tex]f(x)=-6x^4+12[/tex] has an absolute maximum value of [tex]12[/tex].

To find where the maximum value occurs at, the formula:

Tells us the x-value of the vertex of the parabola, whose y-value is the maximum value.

Using our rearranged equation, the a, b, and c-values are:

Plug in the a and c values into the formula to find the x-value of the maximum point:

Therefore, the absolute maximum value of 12 occurs at x = 0.

have an amazing day luv

Answer:

10 students would pay for lunch with $30.

Step-by-step explanation:

This is how I know $30 is the correct answer:

1. To figure out how much money it would cost for 1 student I would take the $12 the four students paid for lunch and divide it by 4 so we would know the exact cost for one students lunch (12/4=3 or $3)

2. Now we know $3 is the cost for 1 student. We can now multiply the $3 by 10 (students) so we can get the cost for 10 lunches (3(10)=30 or $30)

3. We got our final answer of $30=10 students lunches.

A. The parent function reflect across x-axis.

A relation between set of inputs & set of outputs is called function. In a function, for each element of input set there is exactly one element of the set of outputs.

The simplest form of a family of functions is called the parent function. A family of functions always share same highest degree & shape.

If a function has an algebraic expression in absolute value symbols, then the function is called absolute value function.

The parent function y = |x| always go downwards & hence the curve opened upward.

So, The parent function y = |x| reflect across x-axis.
