[tex] \sec(x) - \tan(x) [/tex]Sarah stated that given the following information,
she can prove that the lines 1 and m are not parallel.
Is Sarah correct?
Explain your reasoning.
Answer:
Sarah is correct: lines l and m are not parallel.
Step-by-step explanation:
Given that m < 1 = 130°, and m < 7 = 45°,
Sarah is correct, that lines l and m are not parallel.
If lines l and m were parallel cut by the transversal, n, then its exterior angles < 1 and < 7 that lie on the same side of the transversal should be supplementary. In other words, m < 1 and m < 7 should have a sum of 180°
Since according to the given prompt that m < 1 = 130°, and m < 7 = 45°, the sum of their measure add up to 175°, and not 180°.
Therefore, lines l and m are not parallel.

Answer:
13.896 kg
Step-by-step explanation:
Volume of Gold Bar = Area of [Trapezium x Length of Bar]
Length of Bar = 16 cm
Area of Trapezium = 2 × Area of Triangle + Area of Rectangle
Area of Triangle = 0.5 × 5 × 3 = 7.5 cm²
2 × Area of Triangle = 2 × 7.5 = 15 cm²
Area of Rectangle = 6 × 5 = 30 cm²
Area of Trapezium = 15 + 30 = 45 cm²
Volume of Gold Bar = 45 × 16 = 720 cm³
Density of Gold = 19.3 g/cm³
Mass of Gold Bar = 720 × 19.3 = 13896 g = 13.896 kg
Mass of Gold Bar = 13.896 kg
Therefore the mass of the Gold Bar is: 13.896 kg (kilograms).
Answer:
13.896kg
Step-by-step explanation:
First, find the volume of the trapezium.
Volume = area of cross-sectional area times the length (16cm)
[(a+b)/2] times height
(6+12)/2 x 5
(18/2) x 5
9 x 5
= 45 <-- area of cross section
45 x 16 = 720 cm^3 <-- volume
To find the mass, multiply volume times density
720 x 19.3 = 13 896g = 13.896kg

- 0.2 ( 25x + 5 ) - 5 = 4
Answer:
x= -2
Step-by-step explanation:
-0.2(25x+5)-5 = 4
We move all terms to the left:
-0.2(25x+5)-5-(4) = 0
We add all the numbers together, and all the variables
-0.2(25x+5)-9 = 0
We multiply parentheses
-5x-1-9 = 0
We add all the numbers together, and all the variables
-5x-10 = 0
We move all terms containing x to the left, all other terms to the right
-5x= 10
x= 10/-5
x= -2
Answer:
x=-2
Step-by-step explanation:
step 1 -5x-1-5=4
step 2 -5x-6=4
step 3 -5x=10 cause you add 6 on both sides
step 4 and then divide both sides by -5 to get x=-2

Tim drives at an average speed of 80 km per hour for 2 hours 45 minutes.
Work out how many kilometres Tim drives.
Answer:
220km
Step-by-step explanation:
Time taken (t) = 2hrs 45 min
= 2.75 hrs
AV =80km/hrs
Displacement or Distance (d) =?
We have,
AV = d÷t
80 = d÷2.75
80 × 2.75 = d
d = 220km

What is the ratio of the area of a circle with an 8 m diameter to a
circle with an 8 m radius?
Answer:
8d : 8r = Ratio = 1 : 4
Step-by-step explanation:
Area of 8cm diameter = 4cm radius = formula pi x 4^2
= 50.2654825
= 50.27 m^2 rounded to 2dp as meters
Area of 8cm radius = formula pi x 8^2
=201.06193
= 201.06,^2 rounded to 2dp as meters
201.06193 / 50.2654825 = 4
4 x 50.265 = 201.061
= 1 : 4
8d : 8r = Ratio = 1 : 4
The ratio of the area of circle with an 8m diameter to a circle with an 8m radius is 1:4.
What is ratio?A term that is used to compare two or more numbers and to indicate how big or small a quantity is when compared to another is called ratio.
What is area of circle?Area of a circle is the region covered or enclosed within its boundary.
What is the formula for the area of circle?The formula for the area of circle is give by
[tex]Area = \pi r^{2}[/tex]
Where,
r is the radius of the circle
According to the given question.
We have two circle.
One with the diameter 8m.
⇒ Radius, [tex]r_{1} = \frac{8}{2} =4m[/tex]
Therefore,
the area of circle with 4m radius
= [tex](4)^{2} \pi[/tex]
[tex]=16\pi[/tex]
Also, another circle with the radius 8m.
Therefore,
The area of the circle with the radius 8m
[tex]\pi (8)^{2} \\= 64\pi[/tex]
So,
the ratio of the area of circle with an 8m diameter to a circle with an 8m radius = [tex]\frac{16\pi }{64\pi } =\frac{1}{4}[/tex]
Hence, the ratio of the area of circle with an 8m diameter to a circle with an 8m radius is 1:4.

Answer:
- The graph is decreasing over its entire domain
- The graph is symmetrical about the origin
Step-by-step explanation:
The graph has an unremovable discontinuity at X=0, therefore all continuity answers are incorrect.
The graph is neither symmetrical about the x-axis nor y-axis, but if it were to be rotated around the origin, it would be symmetric.
On both sides of the graph, the slope is decreasing.
Therefore:
- The graph is decreasing over its entire domain
- The graph is symmetrical about the origin

If the directrix is y = 4 and the focus is at
(3,0), the value of p is:
Using the equation of an parabola, it is found that the value of p is 0.5.
The equation of a parabola that is concave to the left or to the right, that is, that has directrix y = k, and vertex (h,k), is given by:
[tex](y - k)^2 = 4p(x - h)[/tex]
The focus is at: (h, k + p).
The directrix is at: y = k - p
For this problem, we have that:
Focus at (0,3), thus [tex]k + p = 3 \rightarrow k = 3 - p[/tex].Directrix at y = 4, thus [tex]k - p = 4[/tex]Since [tex]k = 3 - p[/tex]:
[tex]3 - p - p = 4[/tex]
[tex]2p = 1[/tex]
[tex]p = \frac{1}{2}[/tex]
[tex]p = 0.5[/tex]

what is the slope of the line that passes through (-3,-3) and (-9,5)
The question gives us two points, (-3,-3) and (-9,5), from which we can find the slope and later the equation of the line.
Finding the Slope
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (5 -(-3)) ÷ (-9 -(-3))
= (5 + 3) ÷ (-9 + 3)
= - ⁴/₃
Checking my answer visually:
Finding the Equation
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line. Once we have that equation, we can graph it to see if it passes through the two points. If it does, then we calculated the slope correctly.
⇒ y - (-3) = - ⁴/₃ (x - (-3) [ using the point (-3, -3)]
y + 3 = - ⁴/₃ (x + 3)
