Answer:
(-1, 1)
Step-by-step explanation:
Find the differences between an f(x) value and the previous one
3 -18 = -15
0 -3 = -3
3 -0 = 3
6 -3 = 3
3 -6 = -3
Where the differences are positive, the function is increasing on the interval. Here, it is increasing on the intervals (-1, 0) and (0, 1). Then the longest increasing x-interval is (-1, 1).

what is the value of s in the equation 3r=10+5s when r= 10
Answer:
3×10=10+5s
30=10+5s
30-10=5s
20=5s
5s=20
s=20/5
s=4 ans.
I hope this will help you
Answer:
s= 4
Step-by-step explanation:
solution,
3×10= 10 + 5s
30 = 10+ 5s
30 - 10 = 5s
20 = 5s
20 ÷ 5 = s
4 = s
Therefore, the value of s is 4.
How many solutions does-3x = -x – 2x have?
Answer:
infinite solutions
Step-by-step explanation:
-3x = -x – 2x
Combine like terms
-3x = -3x
Add 3x to each side
-3x+3x = -3x+3x
0 =0
This is always true so there are infinite solutions

Answer:
[tex] \displaystyle B) {x} = \log_{6} 118[/tex]
Step-by-step explanation:
we would like to solve the following exponential equation:
[tex] \displaystyle 2 \cdot {6}^{x} = 236[/tex]
to do so divide both sides by 2 which yields:
[tex] \displaystyle {6}^{x} = 118[/tex]
take log of base 6 in both sides so that we can solve the equation for x by using [tex]\log_ab^c=c\log_ab[/tex] and that yields:
[tex] \displaystyle \log_{6} {6}^{x} = \log_{6} 118[/tex]
use the formula:
[tex] \displaystyle {x} = \log_{6} 118[/tex]
hence,
our answer is B)
Answer:
[tex]\boxed{\sf Option \ B }[/tex]
Step-by-step explanation:
A equation is given to us and we need to find out the value of x . The given equation is ,
[tex]\sf\dashrightarrow 2 \times 6^x = 236 [/tex]
Transpose 2 to RHS , we have ,
[tex]\sf\dashrightarrow 6^x = \dfrac{236}{2} [/tex]
Simplify ,
[tex]\sf\dashrightarrow 6^x =118 [/tex]
Use log both sides with base "6"
[tex]\sf\dashrightarrow log_6 ( 6^x) = log_6 118 [/tex]
Using the property of log ,
[tex]\sf\longmapsto \bigg\lgroup \red{\bf log_p q^r = r log_p q}\bigg\rgroup[/tex]
[tex]\sf\dashrightarrow x \ log_6 6 = log_6 118 [/tex]
Again we know that ,
[tex]\sf\longmapsto \bigg\lgroup \red{\bf log_p p= 1}\bigg\rgroup[/tex]
We have ,
[tex]\sf\dashrightarrow x \times 1 = log_6 118 [/tex]
Therefore ,
[tex]\sf\dashrightarrow\boxed{\blue{\sf x = log_6 118 }} [/tex]
Hence option B is correct .

MN = x+3 = 1+3 = 4
The measurement of MN side is 4
What are the properties of Triangle?The properties of the triangle are:
1. The sum of all the angles of a triangle (of all types) is equal to 180°.
2. The sum of the length of the two sides of a triangle is greater than the length of the third side.
3. In the same way, the difference between the two sides of a triangle is less than the length of the third side.
Since the base angles are the same, the side have to be the same
ML = MN
4x = x+3
Subtract x from each side
4x-x = x+3-x
3x= 3
Divide by 3
3x/3 = 3/3
x = 1
We want the length of MN
MN = x+3 = 1+3 = 4

Answer:
θ = 60.34
Step-by-step explanation:
[tex]\frac{\left(12.8\cdot \:sin\left(90\right)\right)}{sin\left(52.3\right)}[/tex] = 16.177
[tex]\frac{\left(16.177\cdot \:sin\left(90\right)\right)}{18.6}[/tex] = θ = .869
[tex]arcsin\left(.869\right)[/tex] = 60.34
Answer:
60.4°
Step-by-step explanation:
There are two right triangles.
One right triangle (on the left side) has an acute angle measuring 52.3°.
Its opposite leg measures 12.8 cm.
We can find the length of its hypotenuse, x.
sin 52.3° = opp/hyp
sin 52.3° = 12.8 cm/x
x * sin 52.3° = 12.8 cm
x = 12.8 cm/sin 52.3°
x = 16.2 cm
Now we use the hypotenuse of the left side triangle which is a leg of the right side triangle.
For the right side triangle, we are looking for angle Θ. We know the opposite leg, 16.2 cm and the hypotenuse, 18.6 cm.
sin Θ = opp/hyp
sin Θ = 16.2/18.6
sin Θ = 0.8698
Θ = sin^-1 0.8698
Θ = 60.4°

Ramu has to pay 12.5% sales tax in addition to the price of a video player. if he pays 1350, then the price of the video player is________
Answer:
$1200
Step-by-step explanation:
We can use an equation to solve the problem
Given x the price of the the video player :
x + 0.125x = 1350
1.125x = 1350
x = 1350/1.125 = 1200
A biased 3-coloured spinner was spun 240 times. It landed on Red n times, on Orange 3n times and on Yellow 8n times.
If you spin this spinner 1000 times, how many times do you expect it to land on Red?
(Hint: Find n first)
Answer:
83 times.
Step-by-step explanation:
n + 3n + 8n = 240
12n = 240
n = 20.
So we have 20 reds in 240 spins
So by proportion the number expected in 1000 spins
= 20 * 1000/240
= 1000/12
= 83 1/3
So its 83 reds.

the answer is point G
It is found that Point G is the midpoint of AB.
What does a midpoint mean?Midpoint, as the word suggests, means the point which lies in the middle of something. Midpoint of a line segment means a point which lies in the mid of the given line segment.
We are Given two points A and B which are located at -6 and 8 on the number line. We need to find the midpoint of AB.
First we have to calculate the distance between AB which can be calculated as;
8-(-6)=14 units
Now, to find the midpoint we have to divide the total distance by 2.
Hence, the mid point of AB is 7 units apart from both points A and B then G.

ahmed is sitting on a dock watching a float plane in a harbour. At a certain time, the plane is 350 m above the water and 470 m from Ahmed. Determine the angle of elevation of the plane measured from Ahmed, to the nearest degree
Answer:
The angle of elevation of the plane measured from Ahmed is approximately 36.67°
Step-by-step explanation:
The given parameters of the float plane are;
The height of the float plane above the water, y = 350 m
The horizontal distance of the float plane from Ahmed, x = 470 m
Given that Ahmed is sitting on the dock, by the water, by trigonometric ratios, we have;
The height of the float plane, the distance of the plane from Ahmed and the line of sight forming the angle of elevation of the plane measured from Ahmed, form a right triangle
[tex]tan\angle X = \dfrac{Opposite \ leg \ length}{Adjacent \ Leg\ length}[/tex]
Therefore
[tex]tan(\theta) = \dfrac{y}{x}[/tex]
Where;
θ = The angle of elevation of the plane measured from Ahmed
y = The leg of the right triangle opposite the reference angle
x = The leg of the right adjacent to reference angle
Therefore;
θ = arctan(y/x) which gives;
θ = arctan(350/470) ≈ 36.67°
The angle of elevation of the plane measured from Ahmed, θ ≈ 36.67°.
