Given that the four points A(1,2), B(2, -5), C(7,0) and D(p,q) are the vertices of the rhombus ABCD
calculate
a) the value of p and of q
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]

What is the base area of a square pyramid of volume 216 cm3 and height 8 cm?
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

A rectangle has dimensions 8ft x 12ft. It is dilated by a scale factor and has new dimensions of 32 ft x 48 ft. What was the scale factor?
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.

The width of a rectangle is 33 centimeters. The perimeter is at least 776 centimeters.
a. Write and solve an inequality to find the length of the rectangle.
b. Write an inequality to find the area of the rectangle in square centimeters.
A. 2(33) + 2ℓ ≤ 776; ℓ ≤ 355; A ≤ 33(355)
B. 2(33) + 2ℓ ≥ 776; ℓ ≥ 335; A ≥ 33 + 335
C. 33 + ℓ ≥ 776; ℓ ≥ 743; A ≥ 33(743)
D. 2(33) + 2ℓ ≥ 776; ℓ ≥ 355; A ≥ 33(355)
Answer:
D. 2(33) + 2ℓ ≥ 776; ℓ ≥ 355; A ≥ 33(355)
Step-by-step explanation:
Answer:
Width of the rectangle is given to be 33 centimeters
Let the Length of the rectangle be x centimeters
So, Perimeter of rectangle is given by formula : Perimeter = 2 × (Length + Width)
⇒ Perimeter = 2 × (x + 33)
⇒ Perimeter = 2x + 66
Now, The perimeter of the rectangle is at least 776 centimeters
⇒ Perimeter > 2x + 66
⇒ 776 > 2x + 66
⇒ 2x < 710
⇒ x < 355
So, The length of the rectangle must be less than 355 cm
⇒ Area of the rectangle < 355 × 33
⇒ Area of the rectangle < 11715 cm²

Solving inequalities by multiplication and division
1. -8 < 8w
Answer:
w > -1
Step-by-step explanation:
Hello There!
We want to simplify this expression to be more specific we want to isolate the variable (w) using inverse operations
So we want to get rid of the 8 in 8w
8w is the same as 8 times w (multiplication)
The inverse of multiplication is division so to get rid of the 8 we want to divide by 8 but remember whatever we do to one side we want to do to the other side. So we divide each side by 8
-8/8 = - 1
8w/8=w
we're left with w > -1
[tex]\huge\text{Hey there!}[/tex]
[tex]\mathsf{-8 < 8w}[/tex]
[tex]\large\text{TURN/FLIP the given EQUATION around}[/tex]
[tex]\mathsf{8w > -8}[/tex]
[tex]\large\text{DIVIDE 8 to BOTH SIDES}[/tex]
[tex]\mathsf{\dfrac{8w}{8}>\dfrac{-8}{8}}[/tex]
[tex]\large\text{Cancel out: }\mathsf{\dfrac{8}{8}}\large\text{ because that gives you 1}[/tex]
[tex]\large\text{Keep: } \mathsf{\dfrac{-8}{8}}\large\text{ because that helps you compare to the w-value}[/tex]
[tex]\large\text{New equation: } \mathsf{w>\dfrac{-8}{8}}[/tex]

Answer:
What does the question look like in the image below it.
Step-by-step explanation:
Pierre was plotting the quadratic function f(x) = - x ^ 2 + 8x for an exit ticket His work is shown below .
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.

3. In a thunderstorm, the wind velocity in meters per second can be described by the function
v(p)=5.7998−p‾‾‾‾‾‾‾√,
where
p
is the air pressure in millibars. What is the air pressure of a thunderstorm in which the wind velocity is 49.3 meters per second? Round your answer to the nearest tenth of a millibar.
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.
Lines RS, TV, and SW are shown. On a coordinate plane, 3 lines are shown. Line R S goes through (negative 8, 6) and (2, 6). Line T V goes through (negative 6, negative 4) and (8, negative 4). Line S W goes through (2, 6) and (2, negative 8). Which statements are true about these lines? Select three options. Line RS has a slope of 6. Line SW has an undefined slope. Line TV has a slope of 0. Lines RS and TV are parallel. Line SW is perpendicular to line RS, but not to line
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:
Line RS has a slope of 6.Line SW has an undefined slope.Line TV has a slope of 0.Lines RS and TV are parallel.Line SW is perpendicular to line RS, but not to line TV.What is a straight line?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.
