Step-by-step explanation:
under a reflection in the x- axis
a point (x, y ) → (x, - y ) , then
(3, 4 ) → (3, - 4 )
(3, 1 ) → (3, - 1 )
(5, 1 ) → (5, - 1 )
Answer:
Points would be (3,-1) (5,-1) (3,-4)
Step-by-step explanation:
So its asking for a reflection on the x-axis, which means you simply take the shape and move the points to the same spot on the other side of the boldest horrizontal line, or in other words, you can just add a negative to the y variable in the points, because the rule is (x,-y).

Which of the Question A & B?
Answers
Answer:
A) 50 households are randomly selected from the town; 14 own a dog
B) 98
Step-by-step explanation:
A) The first choice is the most logical because it doesn’t factor in the accommodations that the other two do.
B) There are 14 households that own dogs per 50 houses, so multiply by 7 to find how many dogs are in the whole town:
50 x 7 = 350 houses
14 x 7 = 98 households

V = 1/2BHLSolving
V = 1/2 x 7 x 8 x 10V = 7 x 10 x 4V = 280 m³Answer:
280
Step-by-step explanation:
So first lets establish the formula for a Triangular Prism :
1/2 * b * h * l
now lets use the mesurements given to substitute into the formula :
1/2 * 7 * 8 * 10
now lets solve it by first multiplying all the whole numbers together!
7 * 8 = 56
56 * 10 = 560
Finally lets multiply 560 by 1/2 or in other words, divide 560 by 2 :
560/2 = 280
In order to qualify for a role in a play, an actor must be taller than 64 inches but shorter than 68 inches. The inequality 64 < x < 68, where x represents height, can be used to represent the height range. Which is another way of writing the inequality?
x > 64 and x < 68
x > 64 or x < 68
x < 64 and x < 68
x < 64 or x < 68
Answers
Answer: x > 64 and x < 68 is another way of rewriting inequality.
Step-by-step explanation:
To qualify for a role in a play, an actor must be taller than 64 inches but shorter than 68 inches.
⇒The inequality 64 < x < 68, where x represents height,gives the range of height.
⇒In other words range of height can be x > 64 and x < 68 , such that both conditions are applied to single actor.

Answer:

Step-by-step explanation:
The TOTAL amount in the account in 3 years will be

subtract the orignal 40 deposit to get the interest =6.31
[tex]~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$40\\ r=rate\to 5\%\to \frac{5}{100}\dotfill &0.05\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{annually, thus once} \end{array}\dotfill &1\\ t=years\dotfill &3 \end{cases}[/tex]

Frank needs to pay R60 000,00 towards his son’s university fees in three years’ time. If he has R46 150,30 now, at what interest rate per year compounded monthly, must he invest his money?
Answers
Using compound interest, it is found that he must invest his money at a rate of 8.78% a year.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year.In this problem, the parameters are as follows:
t = 3, A(t) = 60000, P = 46150.3, n = 12.
Hence:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]60000 = 46150.3\left(1 + \frac{r}{12}\right)^{12 \times 3}[/tex]
[tex]\left(1 + \frac{r}{12}\right)^{36} = 1.3[/tex]
[tex]\sqrt[36]{\left(1 + \frac{r}{12}\right)^{36}} = \sqrt[36]{1.3}[/tex]
[tex]1 + \frac{r}{12} = (1.3)^{\frac{1}{36}}[/tex]
[tex]1 + \frac{r}{12} = 1.00731451758[/tex]
[tex]\frac{r}{12} = 0.00731451758[/tex]
r = 12 x 0.00731451758
r = 0.0878.
He must invest his money at a rate of 8.78% a year.

A builder wants to install a triangular window with the angles shown in the illustration. What angles will he have to cut to make the window fit? (Hint: The sum of the angles in a triangle equals 180°.)
x° =
°
(x + 30)° =
°
Answers
Answer:
X=40°
Step-by-step explanation:
40+30=70
40+30=70
70+70=140
140+40=180
The angles will builder has to cut to make the window fit is 40°, 70° and 70°.
Given that, the measures of the three angles of a triangle are x°, (x+30)° and (x+30)°.
What is the angle sum property of a triangle?The sum of all internal angles of a triangle is always equal to 180°. This is called the angle sum property of a triangle.
Now, x°+(x+30)°+(x+30)°= 180°
⇒3x+60°=180°
⇒3x=180°-60°
⇒3x=120°
⇒x=40°
So, x°=40°, (x+30)°= 70°
Therefore, the angles will builder has to cut to make the window fit is 40°, 70° and 70°.

Compute the value of the discriminant and give the number of real solutions of the quadratic equation. -9x to the second power-6x-1=0
Answers
discriminant=0
Number of real solutions=1
Step-by-step explanation:
Given the equation:
-9x^2-6x-1=0
Let a: coefficient of x^2
Let b: coefficient of x
Let c: constant
a=-9
b=-6
c=-1
The formula of the discriminant is given by:
discriminant= b^2 - 4ac
discriminant= (-6)^2 - 4(-9)(-1)
= 36 - 36 = 0
We know that:
If discriminant<0 then the equation has no real root
If discriminant=0 the equation has one real root
If discriminant>0 the equation has 2 real roots
Here we got discriminant=0 so the quadratic equation has 1 real root.
