899

Step-by-step explanation:

h[f(10)]=h(30)

=(30)^2-1=900-1=899

The measure of the angle θ in the graph as described in the task content is; 135⁰.

From the task content, it follows that we are required to determine the measure of angle θ in the graph as described.

Since, angle θ transverses the first quarter in the counterclockwise direction, it follows that the measure of angle θ by convention is; 90+45 = 135⁰.

Answer:

V = 945.7 cm^3

Step-by-step explanation:

I'm assuming the carton is a rectangular prism/has right angles. The volume formula for a rectangular prism is V = lwh, where l = length, w = width, h = height.

Substitute known values into this formula:

V = 7 × 7 × 19.3

V = 945.7 cm^3

The rate of change of function 1 is 2

A line is a one-dimensional figure, which has length but no width. A line is made of a set of points which is extended in opposite directions infinitely.

Given function: y = 2x + 7.

As the graph of function 1 is not given.

the rate of change of function 2 : y = 2x + 7.

As the the value of m or rate of change of above equation is 2

m=2.

as,  the horizontal line passes, the rate of change is 0

Hence, rate of change is 2.

Answer (if the number is 10 3/8):

83/8

Step-by-step explanation:

to find out we multiply the whole number (10) by the denominator (x/8) as shown below

10 * 8 = 80

then we just add the product to the numerator (3/y)

3 + 80 = 83

usually we would simplify the new expresion given -wich is 83/8- by finding the least common denominator, however this improper fraction is already in simplest form

Cost of laying sand on this path = Rs. 1372 at the rate of Rs. 7 per sq. m

Step-by-step explanation:

[ refer to attachment ]

Area of field + path = L × B

=> 35 × 18

=> 630 m² -------------(1)

Area of field = L× B

=> 31 × 14

=> 434 m² --------------- (2)

Area of path = area 1 - area 2

=> 630 - 434

=> 196 m²

Given Rate = Rs. 7/ m²

If cost of 1m² = Rs. 7

Cost of 196m² = 7×196

=> Rs. 1372

If the sample is biased, then it does not represent the population. A biased sample favors one or more groups over others.

For example, if the sample consisted of only men, then the sample is biased toward men and leaves out women from the group. Hence, this sample does not represent everyone.

Answer:

See below.

Step-by-step explanation:

To find the surface area, find the area of the square base and add it to the area of each triangle face. Find the area of the base by multiplying base length by base length. Find the area of each triangle face by multiplying 1/2 * b*h.

Example:

For a base which is 12 by 12. The area is 12 x 12 = 144.

For the triangle face, the area is 1/2 * 12 * 15 = 90. Since there are 4 faces, the total area is 4 * 90 = 360.

Together the surface area is 360 + 144 = 504.

Answer:

120 cubes

Step-by-step explanation:

We can find the number of smaller cubes that will fit into larger rectangular prism by dividing the volume of prism by the volume of cube.

  Rectangular prism:

       [tex]\sf l = 2\dfrac{1}{2} =\dfrac{5}{2} \ inches\\\\w = 4 \ inches\\\\h =1\dfrac{1}{2}=\dfrac{3}{2} \ inches\\[/tex]

            [tex]\sf \boxed{\text{\bf Volume of rectangular prism= l * w * h}}[/tex]

                                                                 [tex]\sf =\dfrac{5}{2}*4*\dfrac{3}{2}\\\\= 5*1*3\\\\= 15 \ in^3[/tex]

Cube:

       [tex]\sf side = \dfrac{1}{2} \ inches\\[/tex]

                [tex]\sf \boxed{\text{ \bf Volume of cube = side * side *side}}[/tex]

                                                [tex]\sf =\dfrac{1}{2}*\dfrac{1}{2}*\dfrac{1}{2}\\\\ =\dfrac{1}{8} \ in^3[/tex]

Number of cubes = Volume of prism ÷ volume of a cube

                              [tex]\sf = 15 \div \ \dfrac{1}{8}\\\\=15 *\dfrac{8}{1}\\\\= 120[/tex]

Answer:

3(x -1) / (x + 1)(x + 2).

Step-by-step explanation:

(x-1)/(x^2-2x-3)].[(3x-9)/(x+2)

Factoring the denominator  and 3x - 9:

= (x - 1) / (x + 1)(x - 3)  *  3(x - 3) / (x + 2)

The (x - 3)'s  cancel out, so we have:

(x - 1)/(x + 1) * 3 / (x + 2)

= 3(x -1) / (x + 1)(x + 2).

Answer:

x = 2 and x = 3

Step by step explanation:

[tex]~~~~~~x = 2 +\sqrt{x-2}\\\\\implies x -2 =\sqrt{x-2}\\\\\implies (x-2)^2 = x-2 ~~~~~~~~~~~~~~~;[\text{Square both sides}]\\\\\implies x^2 -4x+4-x +2 = 0\\\\\implies x^2-5x+6 = 0\\\\\implies x^2-3x-2x+6=0\\\\\implies x(x-3)-2(x-3) = 0\\\\\implies (x-2)(x-3) = 0\\\\\implies x =2,~~x = 3\\\\\textbf{Verifying solutions:}\\\\\text{For x =2,}\\\\2= 2+\sqrt{2-2} \implies 2 = 2~ \\\\ \text{So, x = 2 is a solution.}\\\\\text{For x =3,}\\\\3 = 2+\sqrt{3-2}\implies 3=2+1 \implies 3=3\\ \\[/tex]

The maximum number of sales will be equal to 37.

A function in mathematics set up a relationship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.

Given function is:-

The maximum value of d = 3

s(d)  =  d³   +  10

s(d)  = (3)³  +  10

s(d)  = 27  +   10

s(d)  =  37

Using proportions, it is found that Bob will be 90 feet from the surface of the water after 2 minutes.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, every half-minute, he ascends 15 feet. Hence in 2 minutes = 4 half-minutes, he will have ascended 15 x 4 = 60 feet.

He is 150 feet below the surface of the water, hence after 2 minutes he will be 150 - 60 = 90 feet from the surface of the water.
