Answer:

The solutions to the equation are [tex]x = \frac{1}{5}[/tex] and [tex]x = -4[/tex]

Step-by-step explanation:

The factors of the quadratic function g(x) are (5x – 1) and (x + 4).

This means that:

[tex]g(x) = 0[/tex]

[tex](5x - 1)(x + 4) = 0[/tex]

So

[tex]5x - 1 = 0[/tex]

[tex]5x = 1[/tex]

[tex]x = \frac{1}{5}[/tex]

And

[tex]x + 4 = 0[/tex]

[tex]x = -4[/tex]

The solutions to the equation are [tex]x = \frac{1}{5}[/tex] and [tex]x = -4[/tex]

Answer:

Length of one side is 8 units

Step-by-step explanation:

Given

The centre of this square is positioned at the origin as visible form the four co-ordinates

All the four co-ordinates are such that they are 4 units along the x-axis and 4 units along the y-axis.

Let us take the following two co-ordinates - (4,4),(4,−4). The X value for these two co-ordinate points is 4 and the Y values are such that one point has y = 4 and the other has y = -4 i.e 8 units in between.  

Thus, length of one side is 8 units.  

Answer:

60 square units

Step-by-step explanation:

The  area of the trapezoid is 60 square units.

A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles.

The formula for finding the area of a trapezoid is expressed as:

A = 0.5(a+b)h

Given the following parameters

a = AD = √4² + 6²

AD = √16+36

AD = √52

For the length of BC

a = AD = √6² +10²

AD = √36+100

AD = √136

Calculate the height of the trapezium (10, 6) and (8, 12)

H = √6² +2²

H =  √40

A = 1/2(7.21+11.66)×6.33

A = 60 square units

Hence, the  area of the trapezoid is 60 square units

Answer:

The width of the frame is 2 inches

Step-by-step explanation:

The given dimensions of the picture = 7 inches by 7 inches

The area of the picture, A₁ = 7 in. × 7 in. = 49 in.²

The area of the given picture and the frame, A₂ = 81 square inches

Let 'w' represent the width of the frame and whereby the picture is a square, we have;

The area of the picture with the frame, A₂ = 81 in.² = (7 + w) × (7 + w)

A₂ = 81 = (7 + w) × (7 + w) = 49 + 14·w + w²

49 + 14·w + w² - 81 = 0

w² + 14·w - 32 = 0

(x + 16)·(x - 2) = 0

∴ x = -16 or x = 2

Given that 'x' is a natural number, we have;

The width of the frame, x = 2 inches.

Answer:

The area of the roof is 3.80 m².

Step-by-step explanation:

The lateral surface area of an octagonal pyramid is given by:

[tex]A = 2s(\sqrt{4h^{2} + 5.828s^{2}})[/tex]   (1)

Where:

s: is the length of the base edge = 0.5 m

h: is the height                                                                                                      

We can find the height from the slant height (S = 1.9 m):

[tex] S = \sqrt{h^{2} + 1.457s^{2}} [/tex]   (2)

By solving equation (2) for "h" we have:

[tex] h = \sqrt{S^{2} - 1.457s^{2}} = \sqrt{(1.9)^{2} - 1.457(0.5)^{2}} = 1.80 m [/tex]

Now, we can calculate the area of the roof (equation 1):

[tex]A = 2s(\sqrt{4h^{2} + 5.828s^{2}}) = 2*0.5(\sqrt{4(1.80)^{2} + 5.828(0.5)^{2}}) = 3.80 m^{2}[/tex]

Therefore, the area of the roof is 3.80 m².

Answer:

The southern lighthouse is 3.4 miles closer than the northern lighthouse

Step-by-step explanation:

From the figure we see that we need to find the distances AK and BK.

The measure of the third angle K is = 180- 25-35= 120 degrees

Using the sine ratios we can find the two distances

From the figure

The northern distance is given by

20/ sin 120 = kA/ sine 35

KA= 20 sine 35/ sine 120

KA= 13.25 miles

The southern distance is given by

20 /sine 120= KB / sine 25

20 sine 25/ sine 120 = KB

KB= 9.759=9.76 miles

Difference between the two miles =

13.25 miles - 9.76 miles = 3.49 miles

The southern lighthouse is 3.4 miles closer than the northern lighthouse

Randomized block design

Step-by-step explanation:

In the scenario described above, the subjects which are the different car types are grouped into fixed units of 4 called blocks with each unit then assigned randomly to a particular treatment condition, which are the 4 different types of tire. In the end, the mean mileage for each block is taken and compared to that of the other blocks. This type of research design improves the reliability of the result obtained as it also eliminates the occurrence of systematic error in the course of our experiment.

Answer: x^2 +9x+1

Step-by-step explanation: exponents go first (if there are more than 1, highest number to lowest), then x terms, then regular numbers

The polynomial 9x + 1 - x² is rewritten in the standard form and will be - x² + 9x + 1.

A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.

The quadratic polynomial is given as ax² + bx + c. Then the degree of the polynomial will be 2.

The quadratic polynomial is given as,

⇒ 9x + 1 - x²

The polynomial is rewritten in the form of standard form is given as,

⇒ 9x + 1 - x²

⇒ - x² + 9x + 1

The polynomial 9x + 1 - x² is rewritten in the standard form and will be - x² + 9x + 1.

Answer:

Use this to get the area of any circle A = π r²

Step-by-step explanation:

I guess the upper circle has a radio of 10.5 m, then you multiply it by itself and you get that 10.5^2=110.25, and to that you add "π", and the area would be this "110.25π m."

Answer:

The difference is 6.74 * 10^-3 centimeters

Step-by-step explanation:

Firstly, we need to write the numbers as they would occur normally

we have this as;

7.65 * 10^-3 = 0.00765

9.1 * 10^-4 = 0.00091

So by subtracting, we have it that we subtract the value of the diameter of the cell N from that of the cell M since it is a bigger number

we have this as;

0.00765 - 0.00091 = 0.00674 and in scientific form is 6.74 * 10^-3 centimeters
