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

- 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

A basket contains dog toys and dog bones. If six-eights of the items in the basket are dog bones, what is the percent of dog toys in the basket?
Answer:
[tex]\dfrac{2}{8}=25\%[/tex]
Answer: 2/8 (1/4 simplified.) 0.25(decimal form)
Step-by-step explanation:
If 6/8 are dog bones, then we subtract 8/8-6/8. We get 2/8. If the fraction needs to be simplified, then we get 1/4. If a decimal is needed, then we divide 2 by 8. We get 0.25.

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]
The value of p is 0.5.

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.

Step-by-step explanation:
Substitute the given values into the expression

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
Ive tried everything and still dont understand can you help?
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

What is the area of shape b
Answer:
312.5 cm²
Step-by-step explanation:
Since the figures are similar , then
ratio of heights = a : b
ratio of areas = a² : b²
Here linear ratio = 12 : 15 = 4 : 5 , then
ratio of areas = 4² : 5² = 16 : 25
let x be the area of B , the using proportion
[tex]\frac{200}{16}[/tex] = [tex]\frac{x}{25}[/tex] ( cross- multiply )
16x = 5000 ( divide both sides by 16 )
x = 312.5
Area of shape B is 312.5 cm²
