Answer:

p = 923.2 millibar

Step-by-step explanation:

Given that,

The wind velocity can be described by the function as follows :

[tex]v(p)=5.7\sqrt{998-p}[/tex]

Where

p is the air pressure in millibar

Put v = 49.3 m/s in the above function.

[tex]49.3=5.7\sqrt{998-p}[/tex]

Squaring both sides,

[tex]49.3^2=(5.7\sqrt{998-p})^2\\\\2430.49=32.49(998-p)\\\\\dfrac{2430.49}{32.49}=(998-p)\\\\74.80=(998-p)\\\\p=998-74.80\\\\p=923.2\ mbar[/tex]

So, the required pressure is equal to 923.2 millibar.

Answer:

m(h+p) - p÷h + m

h = -1, m = 3, and p = 4

3(-1+4) - 4÷(-1) + 3

= 3(3) - (-4) + 3

= 9 + 4 + 3

Step-by-step explanation:

Answer:

A = x² + 11x + 30

Step-by-step explanation:

For a given rectangle

Length (l) = x + 5

Breadth (b) = x + 6

Now,

Area of rectangle

A = l × b

= (x + 5) × (x + 6)

= x² + 6x + 5x + 30

A = x² + 11x + 30

Thus, The area of rectangle in the form of polynomial is

x² + 11x + 30

Answer:

(a) The table

[tex]\begin{array}{cc}x & {f(x)} & {0} & {0} & {1} & {7}& {2} & {12} & {3} & {15} & {4} & {16} & {5} &{15} & {6} & {12} & {7} &{7} & {8} & {0}\ \end{array}[/tex]

(b) See attachment for graph

(c) He swapped the values of the x and y coordinates for one another

Step-by-step explanation:

Given

See attachment for complete question

Solving (a): Complete the table

[tex]f(x) = -x^2 + 8x[/tex]

[tex]x = 0[/tex]:   [tex]f(0) = -0^2 + 8*0 = 0 + 0 = 0[/tex]

[tex]x = 1[/tex]:   [tex]f(1) = -1^2 + 8*1 = -1 + 9 = 7[/tex]

[tex]x = 2[/tex]:   [tex]f(2) = -2^2 + 8 *2 = -4 + 16 = 12[/tex]

[tex]x = 3[/tex]:   [tex]f(3) = -3^2 + 8 *3 = -9 + 24 = 15[/tex]

[tex]x = 4[/tex]:  [tex]f(4) = -4^2 + 8 *4 = -16 + 32 = 16[/tex]

[tex]x = 5[/tex]:  [tex]f(5) = -5^2 + 8 *5 = -25 + 40 = 15[/tex]

[tex]x = 6[/tex]:  [tex]f(6) = -6^2 + 8 *6 = -36 + 48 = 12[/tex]

[tex]x= 7[/tex]:  [tex]f(7) = -7^2 + 8 *7 = -49 + 56 = 7[/tex]

[tex]x = 8[/tex]:  [tex]f(8) = -8^2 + 8 *8 = -64 + 64 = 0[/tex]

So, the complete table is:

[tex]\begin{array}{cc}x & {f(x)} & {0} & {0} & {1} & {7}& {2} & {12} & {3} & {15} & {4} & {16} & {5} &{15} & {6} & {12} & {7} &{7} & {8} & {0}\ \end{array}[/tex]

Solving (b): Plot the graph

See attachment 2 for graph

Solving (c): Why he was marked as incorrect

By comparing the new attached graph (in b) and the graph of the original question, one will notice that the values of the x and y coordinates are switched.

This is why he was marked as incorrect.

Answer:

50

Step-by-step explanation:

let the number be x

15% of x= 0.15x

0.15x=30

(divide both sides by 0.15)

x= 200

25% of 200 = 25/100 *200

= 50

Step-by-step explanation:

Three coordinates of a Rhombus is given to us. And the fourth coordinate is D(p,q) . Weneedtofind the value of p and q . We know that the diagonals of Rhombus bisect each other at right angles . So lets find the midpoint.

• Midpoint of AC :-

[tex]\tt\to Midpoint_{(AC)}= \bigg(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\bigg)\\\\\tt\to Midpoint_{(AC)}= \bigg( \dfrac{1+7}{2},\dfrac{2+0}{2}\bigg)\\\\\tt\to Midpoint_{(AC)}= \bigg(\dfrac{8}{2},\dfrac{2}{2}\bigg)\\\\\tt\to \boxed{\orange{\tt Midpoint_{(AC)}= (4,1)}}[/tex]

_______________________________

• Midpoint of BD :-

[tex]\tt\to Midpoint_{(BD)}= \bigg(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\bigg)\\\\\tt\to \boxed{\orange{\tt Midpoint_{(BD)}= \bigg( \dfrac{2+p}{2},\dfrac{q-5}{2}\bigg)}}[/tex]

_______________________________

Now since these two coordinates must be equal, therefore ,

[tex]\tt\to \bigg( \dfrac{2+p}{2},\dfrac{q-5}{2}\bigg)= (4,1)\\\\\tt\to \dfrac{2+p}{2}=4 \qquad and \qquad \dfrac{q-5}{2}=1 \\\\\tt\to 2 + p = 8 \qquad and \qquad q-5 = 2 \\\\\tt\to p = 8 -2 \qquad and \qquad q = 2 +5 \\\\\tt\to\boxed{\orange{\tt (p,q) = (6,7) }}[/tex]

Given:

A rectangle has dimensions 8ft x 12ft.

After dilatation the new dimensions of 32 ft x 48 ft.

To find:

The scale factor of the dilation.

Solution:

We know that,

[tex]\text{Scale factor}=\dfrac{\text{Side length of new figure}}{\text{Corresponding side length of original figure}}[/tex]

Dimensions of original rectangle are 8ft x 12ft and dimensions of the new rectangle are  32 ft x 48 ft.  Corresponding side of 8ft is 32 ft and corresponding side of 12 ft is 48 ft.

[tex]\text{Scale factor}=\dfrac{32}{8}[/tex]

[tex]\text{Scale factor}=4[/tex]

Therefore, the scale factor is 4.

Answer:

We have the formula for pyramid volume V = (B.h)/3 => B = 3V / h

=> B = (216 . 3)/8 = 81 m2

the base area of a square pyramid : 81 m2

Step-by-step explanation:

Answer:

81cm2

Step-by-step explanation:

Volume = 1/3Base area * height

216 =1/3x * 8

3/8*216 =8/3x *3/8

x=81cm2

= 2x² + 7/x

Step-by-step explanation:

2x³ + 7/x

= 2 • x • x • x + 7/x

= 2 • x • x • x/x + 7/x

= 2 • x • x + 7/x

= 2x² + 7/x

Here, that would be V = (10 in)(8 in)(3 in)= 240 in^3

Answer:

Volume is 240 inches

Step-by-step explanation:

Volume = Length x Width x Height

 L    W   H       V

Answer:

b, c, d.

Step-by-step explanation:

Statements 2) Line SW has an undefined slope, 3)Line TV has a slope of 0, and 4) Lines RS and TV are parallel are correct.

It is given that there are three lines RS, TV, and SW.

Line RS goes through (-8, 6) and (2, 6).

Line TV goes through (-6, -4) and (8, -4).

Line SW goes through (2, 6) and (2,-8).

It is required to find true statements.

Statements are:

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]m=\frac{y_{2}-y_{1}}{{x_{2}-x_{1}}}[/tex]

Where [tex](x_{1}, y_{1}) and (x_{2}, y_{2})[/tex] are points lie on the line.

1. Finding line RS slope by using the above formula:

   [tex]m=\frac{6-6}{2-(-8)}[/tex]

   [tex]m=0[/tex]

2. similarly finding line SW slope:

   [tex]m=[/tex] ∞

3. similarly finding line TV slope:

   [tex]m=0[/tex]

4. If the two lines are parallel then their slope will be equal.

   The slope of RS = The slope of TV.

   Hence RS and TV are parallel.

5. If two lines are perpendicular then their product of slope will be -1.

   Here we can see the product of the slope of SW and RS is not defined.

   Hence these two lines aren't perpendicular.

Therefore, statements 2, 3, and 4 are correct.
