Step-by-step explanation:
Since three sides of the triangle are same , the triangle is equilateral.
Again every equilateral triangle is also an isosceles triangle.
The angles of an equilateral triangle are the same and is 60°. Therefore it is acute ( < 90°)

Monique’s group will design a float for the I love my city parade. They plan to highlight the city’s train system by making a float of the MetroPass.
*SEE PICTURES FOR ACTUAL MEASURES*
The actual MetroPass is 2.1 inches wide and 3.4 inches long. Moniques group wants the MetroPass float to be 74.8 ft long. Her group needs to find the width of the MetroPass float.
How wide, in feet, will the MetroPass float be? Round you answer to the nearest tenth. Show your work.
*WILL BE MARKED BRAINLIEST*
Answer:
Width = 64.4 feet
Step-by-step explanation:
A scale is a representative faction that can be used to either increase or decrease the dimension of a given object.
scale = [tex]\frac{nem length}{actual length}[/tex]
But,
1 feet = 12 inches
For the actual MetroPass;
length = 3.4 inches = 0.2033 feet
width = 2.1 inches = 0.175 feet
The MetroPass float has a length of 74.8 feet.
scale = [tex]\frac{74.8}{0.2033}[/tex]
= 367.93
So that;
the width of the MetroPass float = 0.175 x 367.93
= 64.388
Therefore, the width of the MetroPass float is 64.4 feet.

If you apply the changes below to the quadratio parent function, f(x) = x2
what is the equation of the new function?
• Shift 1 unit right.
• Vertically stretch by a factor of 5.
• Reflect over the x-axis.
Answer:
[tex]f(x) = -5(x+1)^2[/tex]
Step-by-step explanation:
We are given the following function:
[tex]f(x) = x^2[/tex]
Shift 1 unit right.
Shifting a function a units to the right is finding f(x+a). So
To shift one unit right:
[tex](x+1)^2[/tex]
Vertically stretch by a factor of 5.
To vertically stretch by a factor of 5, we multiply the function by 5. So
[tex]5(x+1)^2[/tex]
Reflect over the x-axis.
To reflect over the x-axis we multiply the function by -1. So
[tex]f(x) = -5(x+1)^2[/tex]

Answer:
5196
Step-by-step explanation:
So it's 5040+(-156)
We have to find the absolute value
|-156|=156
5040+156=5196
Answer:
5196 m
Step-by-step explanation:
The sea is level = 0
If Punack Jaya, is 5040 m above sea level then it would be = + 5040 m
If Lake Assal is 156 m below sea level then it would be = - 156 m
The difference between the two elevations:
= 5040 - (-156)
= 5040 + 156 --> two negatives create a positive
= 5196 m

What is the value of log27 165
The solution of the logarithmic function log₂₇165 found using logarithmic properties is :
(1 + log ₃55)/3.
What is a logarithmic function?
The logarithm is exponentiation's opposite function in mathematics. This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b. The usage of logarithmic functions makes it simple to determine some of the non-integral exponent values. The common logarithmic function, which has a base of 10, is identified by the symbols log₁₀ or log.
We are asked to solve the following logarithmic function.
log₂₇165
Here the base of the log is 27.
According to logarithmic properties, we can write the above functions as:
log₂₇165 = log 165 / log 27
If we are dividing the numerator and denominator by log 3, then the new base will become 3.
(log 165 / log 3) / (log 27/log3) = log ₃165 / log₃ 27
Now we can solve as follows,
log ₃165 / log₃ 27 = log ₃(3*55) / log₃ (3³) = [log ₃(3)+log ₃(55)] / 3log₃3
= (1 + log ₃55)/3
Therefore the solution of the logarithmic function log₂₇165 is
(1 + log ₃55)/3.

A (0,3) (-3,-3)
B (0,6) (-3,0)
C (0,-3) (-3,-9)
D (3,3) (0,-3)
Answer:
A (0,3) (-3,-3)
Step-by-step explanation:
A graph will match the equation if both the coordinates points replaced in the equation generate a identity.
When x = -3
[tex]y + 3 = 2(x + 3)[/tex]
[tex]y + 3 = 2(-3 + 3)[/tex]
[tex]y + 3 = 0[/tex]
[tex]y = -3[/tex]
So (-3,-3) is part of the graph.
When x = 0
[tex]y + 3 = 2(x + 3)[/tex]
[tex]y + 3 = 2(0 + 3)[/tex]
[tex]y + 3 = 6[/tex]
[tex]y = 3[/tex]
So (0,3) is part of the solution.
(-3,-3) and (0,3), so option A.
If a quadratic equation is given to you in vertex form, what is the vertex?
If for example, you were given y = 2(x-3)^2 + 5, then the vertex is (3,5)
As another example, the equation y = 7(x+1)^2 + 10 has the vertex (-1,10)
The general vertex form is y = a(x-h)^2 + k with the vertex (h,k)
Answer:
(-h,k)
Step-by-step explanation:
vertex form:
y＝a(x-h)^2+k
switch sign of h and you get the x
keep sign of k and you get y
ex- 3(x-5)+7
vertex＝（5,7）

I work at a restaurant and earn tips each night.On a busy Saturday night,I predict that i will earn $200 in tips for the night.When i get hom and i count up my total tips,I realize that the percent error is less than 10%.Select all of the following that could represent the amount I earned in tips?
$160
$180
$200
$220
$240
Ok.
You predicted that your tip will be $200.
You realised that you were wrong by less than 10%.
So,
10% of $200
= (10/100) × $200
= $20
So, your actual tip can be less or more by less than $20.
$160 (less than $200 by $40, so error = 20%)
$180 (less than $200 by $20, so error = 10%)
$200 (equal to $200, so error = 0%)
$220 (more than $200 by $20, so error = 10%)
$240 (more than $200 by $40, so error = 20%)
So, your possible actual tips can be:
$200 (equal to $200, so error = 0%)

A meteorologist reports that there is a 30% chance the temperature will fall below freezing tomorrow. On any given day, the bus has a 60% chance of being late.
Assuming the bus travels independently of temperature, what is the probability that a passenger would be waiting for a late bus in freezing weather?
===========================================================
Explanation:
Convert each percentage to decimal form
30% converts to 0.3060% converts to 0.60Then multiply the decimal values
0.30*0.60 = 0.18
That converts to 18%
So there's an 18% chance that both events happen at the same time. In other words, there's an 18% chance of the temperature falling below zero and the bus being late.

Answer:
(x, y) = (-7, 5)
Step-by-step explanation:
I find a graphing calculator to be useful for solving equations by graphing. The graph shows the solution to be ...
(x, y) = (-7, 5)
__
In these equations, the y-coefficients are the same, so we can eliminate y by subtracting the first equation from the second.
(4x -6y) -(-2x -6y) = (-58) -(-16)
6x = -42 . . . . . . . . . simplify
x = -7 . . . . . . . . divide by 6
Substituting into the first equation gives ...
-2(-7) -6y = -16
6y = 30 . . . . . . . . . . add 16+6y to both sides
y = 5 . . . . . . . . .divide by 6
The solution is (x, y) = (-7, 5).
