What are similar triangles?
If two triangles' corresponding angles and sides are identical and their corresponding sides are proportional, or if the ratios between the lengths of the corresponding sides are comparable, then two triangles are said to be similar.
Similar triangles are triangles with the same shape but different sizes. Examples of related objects are all equilateral triangles and squares with any side length.
The triangles ONP and LNM are similar triangles.
So, the following is true.
(ON/LN)=(NP)/(NM)
(3.6/6)=(6)/(NM) ( LN=LO+ON=2.4+3.6=6 )
3.6 NM=6*6 =36
NM=36/3.6 = 10
So, the length of NM is 10 units

The value of a and b in the function f(x) = √ x+2 and g(x) = ax + b , is a = 0 and b = 2 .
In the question ,
it is given that ,
the function f(x) = √(x+2) and the function g(x) = ax + b
also given that
fog(1) = 2
f(g(1)) = 2
f(a + b) = 2 .... because g(1) = a + b
√(a + b +2) = 2

Consider the following linear equation.
y=2+34x
Step 1 of 2 : Determine the slope and the y-intercept (entered as an ordered pair) of the equation above. Reduce all fractions to lowest terms.
Answers
The slope of the function y = 2 + 34x is 34 and the y-intercept of the function y = 2 + 34x is 2.
First, let us understand the slope intercept form;
The slope intercept form is simply a way of writing a line's equation so that the slope (steepness) and y-intercept (where the line crosses the vertical y-axis) are obvious.
We know that the slope intercept form of a line is y = mx + c where m is the slope of the line and b is the y-intercept of the line.
We are given:
y = 2 + 34x
y = 34x + 2
Compare with y = mx + c, we will get;
m = 34
b = 2
So, the slope is 34 and the y-intercept is 2.
Thus, the slope of the function y = 2 + 34x is 34 and the y-intercept of the function y = 2 + 34x is 2.

Answers
The solution of the given system of equations is (-1, -2).
Explain the method of substitution?Three steps make up the substitution technique: For each of the variables, solve one equation. Put this expression (or plug it in) into the other equation, then solve it. To identify the corresponding variable, rewrite the value's original equation.We are aware that a linear system of equations can be solved using a substitution method.
The intersection of the two lines represents the system's solution.
The given equations are-
y = 3x+1 ...eq 1
y = -2x-4 ...eq 2
Put the value of eq 1 in eq2 .
3x+1 = -2x-4
3x + 2x = -4 - 1
5x = -5
x = -5/5
x = -1
Put the x in eq 1.
y = 3(-1)+1
y = -2

Write an equation in point-slope form
using the point (8, -4).
-
y + 4 = [?] (x −
Enter
Answers
Answer:
y + 4 = -(x - 8)
Step-by-step explanation:
The point-slope form equation is y - y1 = m(x - x1)
Since we're given m and since they use the 4 from (8, -4) as y - (-4) = y+4, we simply need to plug in 8 into the RHS of the equation and you can check the math.
If you substitute 8 and -4 for y and x, you have:
-4 + 4 = -1(8 - 8)
0 = -1 * 0
0 = 0
You'd get -2 on both sides if you used -6 and 10, but having an equal equation means our math is true/accurate.

One year consumers spent an average of $23 on a meal at a restaurant. Assume that the amount spent on a restaurant meal is normally distributed and that the standard deviation is $5.
A) What is the probability that a randomly selected person spent more than $25?
B) What is the probability that a randomly selected person spent between $12 and $21?
C) Between what two values, symmetrically distributed around the mean, will the middle 95% of the amounts of cash spent fall?
Answers
Using the normal distribution, it is found that:
a) The probability that a randomly selected person spent more than $25 is of 0.3446 = 34.46%.
b) The probability that a randomly selected person spent between $12 and $21 is of 0.3307 = 33.07%.
c) The middle 95% of the amounts are between $13.2 and $32.8.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The mean and the standard deviation for the costs of the meal are given as follows:
[tex]\mu = 23, \sigma = 5[/tex]
The probability that a randomly selected person spent more than $25 is one subtracted by the p-value of Z when X = 25, hence:
Z = (25 - 23)/5
Z = 0.4
Z = 0.4 has a p-value of 0.6554.
1 - 0.6554 = 0.3446 = 34.46%.
The probability that a randomly selected person spent between $12 and $21 is the p-value of Z when X = 21 subtracted by the p-value of Z when X = 12, hence:
X = 21:
Z = (21 - 23)/5
Z = -0.4
Z = -0.4 has a p-value of 0.3446.
X = 12:
Z = (12 - 23)/5
Z = -2.2
Z = -2.2 has a p-value of 0.0139.
0.3446 - 0.0139 = 0.3307 = 33.07%.
The normal distribution is symmetric, meaning that the bounds of the middle 95% of values are given as follows:
2.5th percentile: X when Z = -1.96.97.5th percentile: X when Z = 1.96.-1.96 = (X - 23)/5
X - 23 = -1.96 x 5
X = $13.2
1.96 = (X - 23)/5
X - 23 = 1.96 x 5
X = $32.8

The graph shows the cost of grapes at a grocery store. What is the slope of the line?
Answers
The slope of the line shown in the graph is 4.5 .
In the question ,
it is given that ,
the amount of grapes is represented on x axis . and
the cost for that grape in the grocery store is represented on y axis .
to find the slope we need two points on the line ,
from the graph we can take two points as (1 , 4.5) and (2 , 9) ,
the slope can be calculated using the formula
slope = (change in y coordinate)/(change in x coordinate)
slope = (9 - 4.5)/(2 - 1)
slope = 4.5/1
slope = 4.5 .
