have a good day friend :)
Which expression calculates the speed in meters per second of an object that travels a distance of 40 m every 10 s?
10÷40
or
40 + 10
or
40/10
or
40×10
Answer:
40/10 [4 meters/sec]
Step-by-step explanation:
Watch for what the units are telling us. The number that is being requested
is speed in units of meters/sec. We are given 40 meters and 10 seconds. If we divide 40 meters by 10 seconds (10 meters/10 seconds), we get 4 meters/sec, the correct dimension.

Find the measure of x.
Round your answer to the nearest hundredth.
Answer:
x=3.42
Step-by-step explanation:
[tex] \sin(20) = \frac{x}{10} [/tex]
[tex]x = 10 \sin(20) = 3.42[/tex]
Answer:
x = 3.420 (to the nearest hundredth)
Step-by-step explanation:
Trig ratios:
sin(x) = O/H
cos(x) = A/H
tan(x) = O/A
where x is the angle, O = side opposite the angle, A = side adjacent to the angle, H = hypotenuse
We have been given:
angle = 20°
opposite side to angle = x
hypotenuse = 10
Therefore, we should use sin(x) = O/H
Substituting the above values into the trig ratio:
⇒ sin(20) = x/10
⇒ x = 10 sin(20)
⇒ x = 3.420 (to the nearest hundredth)

Answer: f(x) = 3x^(2)-2x+1
f(x) = 3x^(2)-2x+1 = y-intercept (0, 1).
g(x) = -10x^(2)+50x = y-intercept (0, 0).
As we see, the first equation (f(x) = 3x^(2)-2x+1) has a y-intercept of (0, 1), while the other equation (g(x) = -10x^(2)+50x) has a y-intercept of (0, 0). This means that the quadratic equation that has the greatest y-intercept is f(x) = 3x^(2)-2x+1, which is (0, 1).

Answer:
inverse: [tex]f^{-1}(x) = \sqrt[5]{x^3 - 5}[/tex]
explanation:
Given: f(x) = [tex](x^5 +5)^{\frac{1}{3} }[/tex]
let f(x) be y
y = [tex](x^5 +5)^{\frac{1}{3} }[/tex]
To find inverse, make x the subject.
[tex]y^3 = x^5 + 5[/tex]
[tex]y^3 - 5 = x^5[/tex]
[tex]x = \sqrt[5]{y^3 - 5}[/tex]

O Subtraction Property of Equality
Commutative Property of Addition
o Associative Property of Addition
Addition Property of Equality
Answer:
Addition Property of Equality
Step-by-step explanation:
Addition Property of Equality.
The addition property of equality justifies the work done in Line 3. This is because it essentially states that if you add something to one side of an equation, you must add it to the other side as well. In this case, we are adding 22 to both sides of the equation, therefore we are making use of the Addition Property of Equality.

The area of a rectangular vegetable patch is 32 square meters. The perimeter is 24 meters.
What are the dimensions of the vegetable patch?
Please help
Answer:
When l = 4m , breadth is 8m
When l = 8m , breadth is 4m .
Step-by-step explanation:
Here it is given that the area of a rectangular patch is 32m² . If we assume length to be l and breadth to be b , then ;
[tex]\longrightarrow Area_{rectangle}=length\times breadth\\ [/tex]
[tex]\longrightarrow 32m^2 = lb \dots (i) [/tex]
Again , it's given that the perimeter is 24m .We know that perimeter of a rectangle is ,
[tex]\longrightarrow Perimeter = 2(l+b)\\ [/tex]
[tex]\longrightarrow 24 = 2( l +b)\\ [/tex]
[tex]\longrightarrow l + b = 12\dots (ii) [/tex]
From equation (i) and (ii) , we have ;
[tex]\longrightarrow l + \dfrac{32}{l}=12\\\\\longrightarrow \dfrac{l^2+32}{12}=1\\\\\longrightarrow l^2+32=12l \\\\\longrightarrow l^2-12l +32=0\\\\\longrightarrow l^2-4l -8l +32=0 \\\\\longrightarrow l( l -4) -8(l-4)=0\\\\\longrightarrow(l-4)(l-8)=0 \\\\\longrightarrow \underline{\underline{ l = 4,8}} [/tex]
Therefore , we can find breadth as,
[tex]\longrightarrow l + b =12\\\\\longrightarrow b = 12 - l \\\\\longrightarrow b = 12-8, 12-4\\\\\longrightarrow \underline{\underline{b = 4,8}}[/tex]

What is the distance between the points A(2,11) and B(−7,9) ? Round to the nearest tenth if necessary.
Step-by-step explanation:
the distance between 2 points is the Hypotenuse of a right-angled triangle with the legs being the x coordinate difference and the y coordinate difference.
so, Pythagoras applies.
c² = a² + b²
distance² = (2 - -7)² + (11 - 9)² = 9² + 2² = 81 + 4 = 85
distance = sqrt(85) = 9.219544457... ≈ 9.2
The distance between the points A(2,11) and B(−7,9) is d = √85.
What is Distance Formula?There are two points (a, b) and (c, d) then the distance between two points is
d= √(c -a)² + (d-b)²
We have the points A(2, 11) and B(-7, 9).
Using the Distance Formula
d = √(-7-2)² + (9-11)²
d= √(-9)² + (-2)²
d= √81 + 4
d = √85
Thus, the distance between points is √85 unit.
