What is the value of the expression below written in scientific notation? and explain

Step-by-step explanation:

area of quadrilateral = sum of area of triangles

area of triangle ADC = .5 * b * h

= .5 * 12 * 5 = 30 km^2

area of ∆ABC = .5 * sinx* ab* ac

= .5 * sin 30 * 3* 13 = 39/4 = 9.75 km^2

area of quadrilateral = 39.75 km^2

total cost =$ 397.5 million

The possible value of x is 2, and the possible dimensions are 8 ft by 11 ft

The equation is given as:

(6 + x) * (9 + x) = 88

Express 88 as a product of two factors

(6 + x) * (9 + x) = 8 * 11

Express 8 and 11 as a sum

(6 + x) * (9 + x) = (6 + 2) * (9 + 2)

By comparison, we have:

6 + x = 6 + 2

9 + x = 9 + 2

This means that

x = 2

So, we have:

The possible value of x is 2, and the possible dimensions are 8 ft by 11 ft

Answer:

c x=8.7

Step-by-step explanation:

length of the 2 shortest sides squared and the length of the longest side square would be x^2+25=100

x^2=75

which would be x=8.7

16 > i - 4

16+4 > i-4+4

20 > i

i < 20

In the second step, I added 4 to both sides to undo the -4

In the last step, I swapped both sides and I flipped the inequality sign.

If you want to graph this on a number line, then plot an open hole at 20. Then shade to the left to represent all the values smaller than 20.

The model in which the lateral surface meets the base at right angle is : Model 1.

The lateral surface of an object is all surfaces  of that object excluding its base and top.

Analysis:

To know the exact model, we check for the models in which their dimensions form a Pythagorean triplet otherwise a right-angled triangle.

For Pythagorean triplet, the square of the diagonal must be equal to the sum of squares of the other two sides.

Model 1

Diagonal = 50cm, radius = 14cm, lateral height = 48cm

[tex](50)^{2}[/tex] = [tex](14)^{2}[/tex] + [tex](48)^{2}[/tex]

2500 = 196 + 2304

2500 = 2500. Forms Pythagorean triplet

Model 2

Diagonal= 37cm, radius = 6cm  lateral height = 35cm

[tex](37)^{2}[/tex] = [tex](35)^{2}[/tex]+ [tex](6)^{2}[/tex]

1369 = 1225 +36

1369 [tex]\neq[/tex] 1261

Model 3

Diagonal = 60cm, radius = 20cm  lateral height = 40cm

[tex](60)^{2}[/tex] = [tex](20)^{2}[/tex] + [tex](40)^{2}[/tex]

3600 = 400 + 1600

3600 [tex]\neq[/tex] 2000

Model 4

Diagonal = 30cm, radius = 24cm, lateral height = 9cm

[tex](30)^{2}[/tex] = [tex](24)^{2}[/tex] + [tex](9)^{2}[/tex]

900 = 576 + 81

900 [tex]\neq[/tex] 657

Therefore the lateral surface model 1 meets the base at right angle

In conclusion,  the lateral surface of model 1 meets the base at right angles as the dimensions form a right-angled triangle.

Answer:

the answer is B have an amazing day

Step-by-step explanation:

A) factor f(x) are 3/5 and -1.

B) x-intercepts of the graph of f(x)  are (3/5, 0) and (-1, 0).

C)  The end behavior is explained by vertex of the graph which is (-0.2, -3.2)

D) The graph is symmetrical about x = -0.2. shown below

Factorizing is a way of writing an expression as a product of its factors using brackets.

Given function is : 5x² + 2x − 3

A)5x² + 2x − 3

= 5x² + 5x-3x − 3

= 5x(x+1)-3(x+1)

=(5x-3)(x+1)

So, factors will be 3/5 and -1.

B) f(x)= 5x² + 2x − 3

The x-intercepts are when f(x) = 0.

So, x-intercepts are (3/5, 0) and (-1, 0).

C) The x-coordinate of the vertex is the midpoint of the zeros.

 midpoint= (3/5-1)/2

                =-0.2

To find the y-coordinate of the vertex, substitute the found value of x into the given equation:

f(-0.2)= 5(-0.2)² + 2(-0.2) − 3

=-3.2

So, the end behavior is explained by vertex of the graph which is (-0.2, -3.2)

D) By plotting the zeroes and the vertex of the f(x).

The axis of symmetry is the x value of the vertex.

Thus,   the graph is symmetrical about x = -0.2.

Answer:

0.0833

Step-by-step explanation:

1 out of 12 can be written as a fraction 1/12

Now we convert the fraction to a decimal with division. Using long division the 12 goes outside the division symbol and 1 on the side. 12 doesn't go into 1 so we add a decimal to the answer and a 0 after the 1. 12 doesn't go into 10 so we add another 0. 12 goes into 100 8 times. 8 goes on top after 0.08 and then we finish the long division. We would have 4 remaining. Add another 0. 12 goes into 40 3 times. This is then where the division becomes repetitive. With more threes. Depending on where youryou're supposed to Round to the answer is 0.0833

The value of A+B is 16

To solve it, we will: divide the number after the equality, by the total number of variables (letters) that have.

A + B + A + D = 32

32 ÷ 4 = 8

< We know that the value of each variable is 8. So, to find the value of A + B, let's just add their respective values.

A + B

8 + 8 = 16

So, the value of A + B will be 16

The median is also known as the middle of the data set when it has already been sorted.  So the first thing that we need to do is make sure that our data set is fully sorted.

[tex]19, 19, 20, 21, 23, 24, 25, 26, 27, 29, 33[/tex]

Now that we have our data set sorted, we can located the middle.  Since this data set has 11 numbers that means number 6 is going to be our median.  Counting from the left we get that our median is 24.

Hope this helps!  Let me know if you have any questions

Answer: The answer is 24.

Step-by-step explanation: To find the median, you put all your data in order from least to greatest, which would look like:

19, 19, 20, 21, 23, 24, 25, 26, 27, 29, 33

Then, cross out the numbers from front to back until you find your middle number.

19, 19, 20, 21, 23, 24, 25, 26, 27, 29, 33

This leaves 24 left, which is the answer!

The simplified value of the exponential expression is 2.

Here we need to simplify the expression:

[tex]16^{1/4}[/tex]

First, you need to remember that:

[tex]\sqrt[n]{x} = x^{1/n}[/tex]

Then we can just write:

[tex]16^{1/4} = \sqrt[4]{16}[/tex]

And now, you can remember that:

2*2 = 4

Then:

2*2*2*2 = 4*4 = 16

From this, we can conclude that:

[tex]2^4 = 16\\\\\sqrt[4]{16} = 2[/tex]

Step-by-step explanation:

We can define ratio a to b as 12:3. If we are finding the value of A when B is 3, we go to the ratio. The ratio says that when B is 3, A is 12. Therefore, A is 12.

Answer:

A = 12

Explanation:

Given:

A ∝ B

set "k" constant

A = k(B)

Find "k"

12 = k(3)

k = 4
