Answer:
∠ AFE = 35°
Step-by-step explanation:
∠ EFD = ∠ BFC = 55° ( vertically opposite angles )
Since BD is a straight line , then
∠ EFD + ∠ AFE + AFB = 180°, that is
55° + ∠ AFE + 90° = 180
∠ AFE + 145° = 180° ( subtract 145° from both sides )
∠ AFE = 35°

Given a quadratic equation px^2 + 8x + 2 does not have real roots. Determine the range of the values of p.
[4 marks]
Step-by-step explanation:
For a quadratic equation to have no real roots, the discriminant b² - 4ac must be negative.
For px² + 8x + 2 = 0,
We have a = p, b = 8 and c = 2.
=> (8)² - 4(p)(2) < 0
=> 64 - 8p < 0
=> 8p > 64
=> p > 8
Hence the range for p is p > 8.

-3x-8>19?I have to solve for x
Answer:
x < -9
Step-by-step explanation:
Add 8 to both sides:
-3x - 8 > 19
-3x > 27
Divide each side by -3:
-3x > 27
Dividing by a negative number on each side switches the inequality:
x < -9
So, the answer is x < -9
Answer:
[tex] \huge \: x < - 9[/tex]

Answer:
Part A
Scale factor

Step-by-step explanation:
Justin is working with a microscope that magnifies objects to 175 times their actual size.
Part A
Enter a number in each box to determine the scale factor for the microscope.
= 1 : 175
Part B
The diameter of an amoeba cell is 0.30 millimeter. How big will the cell appear to Justin under the microscope?
Scale factor =
1 : 175
Diameter of the Amoeba cell = 0.3mm
1mm = 175 mm
0.3mm = x
Cross Multiply
x = 0.3 × 175
x = 52.5 mm
Part C
What is the percent increase of the area of the amoeba cell under the microscope?
Increase = 52.5 mm - 0.3mm
= 52.2 mm
Percent increase
= 52.2/52.5 × 100
= 99.4%
Solve 7+2x over 3 = 5
Please and thank you! x
Answer:
x = 4
Step-by-step explanation:
(7 + 2x) / 3 = 5
Cross product
7 + 2x = 5 * 3
7 + 2x = 15
Subtract 7 from both sides
2x = 15 - 7
2x = 8
Divide both sides by 2
x = 8/2
x = 4

The side length of the base of a square pyramid is 30 centimeters. The height of the pyramid is 45 centimeters.
What is the volume of the pyramid in cubic centimeters?
Answer:
volume = 13500 [tex]cm^{3}[/tex]
Step-by-step explanation:
For a given pyramid, its volume can be determined by:
volume of pyramid = [tex]\frac{lwh}{3}[/tex]
Where: l is the base length, w is the base width and h id the height of the pyramid.
For the given question, l 30 cm, w = 30 cm and h = 45 cm.
So that,
volume = [tex]\frac{30*30*45}{3}[/tex]
= [tex]\frac{40500}{3}[/tex]
= 13500
volume = 13500 [tex]cm^{3}[/tex]
The volume of the pyramid is 13500 [tex]cm^{3}[/tex].
The volume of the square-based pyramid is [tex]13500cm^3[/tex]
The volume of a pyramid is given by
[tex]V=\dfrac{Ah}{3}[/tex]
where
[tex]A=\text{area of the square base}\\h=\text{perpendicular height}[/tex]
The area of the square base, [tex]A[/tex], is calculated as follows
[tex]A=side^2\\=(30cm)^2\\=900cm^2[/tex]
substitute the value of [tex]A[/tex], and [tex]h[/tex] ([tex]45cm[/tex]) into the volume formula to calculate the pyramid's volume
[tex]V=\dfrac{Ah}{3}\\\\=\dfrac{900\times 45}{3}\\\\=13500cm^3[/tex]
Therefore, the volume of the pyramid is [tex]13500cm^3[/tex]

SOLVE USING SUBSITUTION

Answer:
( 1, 5 )
x = 1
y = 1
Step-by-step explanation:
y = x + 4
2x + 3y = 17
Since they gave us the value of "y" we can use that and substitute it into the equation to find what "x" is.
2x + 3y = 17
2x + 3 ( x + 4 ) = 17
Distributive Property
2x + 3 * x + 3 * 4 = 17
2x + 3x + 12 = 17
Combine Like Terms ( 2x and 3x)
5x + 12 = 17
Subtract 12 on both sides of the equation
5x + 12 - 12 = 17 - 12
5x = 5
Divide by 5 on both sides to isolate the variable
5x/5 = 5/5
x = 1
Now that we have what "x" is, we can substitute that into one of the equations to get the value of "y"
y = x + 4
y = 1 + 4
y = 5
x = 1
y = 5
( x, y )
