The point-slope form:
m - slope
(x₁, y₁) - the point
The formula of a slope:
We have the points (5, 4) and (2, -2). Substitute:
- <em>point-slope form</em>
<em>add 4 to both sides</em>
- <em>slope-intercept form</em>
<em>subtract 2x from both sides</em>
<em>change the signs</em>
- <em>standard form</em>
-------------------------------------------------------------------
From the table we have two points (1, 3) and (2, 7). SubstituteL
- <em>point-slope form</em>
<em>add 3 to both sides</em>
- <em>slope-intercept form</em>
<em>subtract 4x from both sides</em>
<em>change the signs</em>
- <em>standard form</em>
Answer:
5 + 2.5 > 4 feets
4 + 5 > 2.5 feets
2.5 + 4 > 5 feets
Step-by-step explanation:
The triangle states that :
The sum of any 2 sides of a triangle must be greater than the third side
Side Given are :
5feets ; 2.5 feets ; 4 feets
In other to obey the triangle rule :
5 + 2.5 > 4 feets
4 + 5 > 2.5 feets
2.5 + 4 > 5 feets
The value of f(h(2)) =2 and h(f(16))= 14
<h3>What is function?</h3>
Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input . Mapping or transformation is used to denote a function in math. These functions are usually denoted by letters . The domain is defined as the set of all the values that the function can input while it can be defined. The range is all the values that come out as the output of the function involved.
given:
f(x)= √x-1 , h(x)= x² + 5
Now,
f(h(2))= f( (2)² +5 )
=f(4+5)
=f(9)
=√9-1
= 3-1
=2
h(f(16)) = h( √16-1)
=h( 4-1)
=h(3)
=3² + 5
=9+5
=14

Answer:
The correct option are;
1) Could not
2) Is
Step-by-step explanation:
The parameters given are;
The survival rate of drivers using seat-belt = 67%
The survival rate of drivers not using seat-belt = 41.5%
The chance of getting the survival rate results without a correlation with the use of seat-belt < 0.0001
Given that the chance of obtaining the given survival rates without the seat-belt having an effect on survival rate is less than 0.01 percent we have;
The probability shows that the sample results <u>could not</u> have occurred by chance. It appears that there <u>is</u> sufficient evidence to conclude that seat-belts do have an effect on survival rate.
