Please help! How are you supposed to fill in something that isnt there? If you took the derviative of x wouldn't it be one?
Answer:
f'(5) = 1
Step-by-step explanation:
You are right. The derivative of f(x) = f'(x) = 1 a constant
If you plot y = f'(x) = 1 it will be a vertical line passing through x = 1 (See graph)
This means f'(x) is constant and equal to 1 for all values of y
So whether it is f'(5) or f'(100) the value = 1
f'(5) = 1
A map is drawn to a scale of 28 miles per inch.
inches: 0.5 miles: 14
inches: 1 mile 28
inches: 1.5 miles 42
The British imperial and American customary systems of measurement both use the inch as their standard unit of length (symbolized as in or ′′). It is equivalent to 1/36 of a yard or 1/ 12 of a foot. The term inch, which is often used to translate comparable units in other measurement systems and is derived from the Roman uncia ("twelfth"), is generally considered to refer to the breadth of the human thumb.
Since the international yard was adopted in the 1950s and 1960s, standards for the precise length of an inch have varied, but the inch is now based on the metric system and is defined as precisely 25.4 mm.

Ruben is driving along a highway that passes through Barstow. His distance d, in miles, from Barstow is given by the equation
d = |210 − 60t|,
where t is the time, in hours, since the start of his trip and
0 ≤ t ≤ 5.
When will Ruben be exactly 90 miles from Barstow?
Answer:
after 2 hours, andafter 5 hoursStep-by-step explanation:
Given that Ruben's distance from Barstow is d = |210 -60t|, you want to know the time t when he is exactly 90 miles from Barstow.
SetupThe absolute value will be 90 when the argument of the function is either -90 or +90.
The question resolves to two equations:
210 -60t = -90210 -60t = 90SolutionThese two-step linear equations can be solved in the usual way:
-60t = -300 . . . . subtract 210-60t = -120Then ...
t = -300/-60 = 5 . . . . divide by the coefficient of tt = -120/-60 = 2Ruben is 90 miles from Barstow after driving 2 hours, and again after driving 5 hours.

on a map, two cities are 5 1/2 inches apart. the map uses a scale of 2 inches =75 miles
what is the actual distance between the two cities?
Answer:
187.5 miles
Step-by-step explanation:
We can use the rationing method to solve for this problem.
2 inches on map = 75 miles actual distance
1 inch on map = (75 ÷ 2) = 37.5 miles actual distance
5.5 inches on map = (37.5 × 5) = 187.5 miles actual distance

The length of a shadow of a building is 10 m. The distance from the top of the building to the tip of the shadow is 26 m. Find the height of the building
Answer:
The height of the building is 24m
Step-by-step explanation:
This can be solved using the Pythagorean theorem
which states that the three sides of a right triangle are related by the equation
[tex]c^2 = a^{2} + b^{2}[/tex] (see figure)
where c is the hypotenuse and a, b are the other two sides
Here we have c = the distance from the top of the building to the tip of the shadow = 26m
One side, the length of the shadow ie b = 10 m
So we have
[tex]26^2 = a^2 + 10^2[/tex] where a is the height of the building
Switch sides to get
[tex]a^2 + 10^2 = 26^2[/tex]
[tex]a^2 + 100 = 676[/tex]
Subtract 100 from both sides
[tex]a^2 = 676 - 100 = 576[/tex]
[tex]a = \sqrt{576}[/tex]
a = 24
The height of the building is 24m
A plastic boulder was launched from a second-floor window, using a catapult. The function below represents the height of the
plastic boulder from the ground, h(t), in feet, over time, t, in seconds.
h(t) = -2x² + 2x + 40
How many seconds did it take for the plastic boulder to hit the ground?
Answer:
5 seconds
Step-by-step explanation:
Given the height function h(t) = -2x² + 2x + 40, you want the positive value of t such that h(t) = 0.
SolutionThe given function can be factored as ...
h(t) = -2(x -5)(x +4)
This will be zero when the factors are zero:
x -5 = 0 ⇒ x = 5
x +4 = 0 ⇒ x = -4
The positive value of t for which the height is zero is t = 5.
It took 5 seconds for the plastic boulder to hit the ground.
__
Additional comment
There are several methods available for factoring the equation. One is to factor out the leading coefficient, then factor the remaining quadratic.
-2(x² -x -20)
To factor this, you're looking for factor pairs of -20 that have a sum of -1.
-20 = -20(1) = -10(2) = -5(4)
The last of these, {-5, 4} has a sum of -1. These are the constants that go into the binomial factors.
A package of 88 batteries costs $ 4 . 724.72 .
What is the cost per battery?
We get that the cost of the battery is $ 8.24 per battery.
We are given that the cost of 88 batteries = $ 724.72
We need to find the cost of one battery.
We will do this by diving the cost of 88 batteries by 88.
Using division, we get that:
cost of one battery = $ 724.72 ÷ 88
Simplifying the expression, we get that:
cost of one battery = $ 8.24 per battery.
Therefore, we get that the cost of the battery is $ 8.24 per battery.

maths geometry
Step-by-step explanation:
trapezium means especially
AD || BC
AC = BC tells us that ABC is an isoceles triangle (both legs are identically long, which makes also their angles with their baseline AB equal).
therefore, A1 = B = 80°.
and because the sum of all angles in a triangle is always 180°, we get
180 = 80 + 80 + C1
C1 = 20°
(e)(1)
because of the law of a line intersecting parallel lines with the same angles, and AC is intersecting the parallel lines AD and BC, we know that
C1 = A2 = 20°
(e)(2)
because also the sum of all angles around a single point on one side of a line is 180°, we know D1 + D2 = 180°.
we also know that D2 is an angle in an equilateral triangle (that means all 3 sides are equally long, and therefore all 3 angles are equal too = 180/3 = 60°) and therefore
D2 = 60°.
therefore, D1 = 180 - 60 = 120°.
so, for the triangle ACD we have
180 = A2 + D1 + C2 = 20 + 120 + C2
C2 = 40° = 2×20 = 2×C1
(f)(1)
a kite is a quadrilateral, and as such the sum of all angles is 360°.
again remember the symmetry of a kite, so the angles at H and at F must be equal.
H = F = x
so, we have
360 = 110 + 50 + H + F = 110 + 50 + 2x
200 = 2x
x = 100°
(f)(2)
after drawing EG we see that this line splits the kite into 2 equal (ahem, congruent) triangles due to the symmetry of a kite exactly along that line.
and that splits both angles E and G in half for each of the triangles.
again, the sum of all angles in a triangle is 180°, so
180 = 110/2 + 50/2 + x = 55 + 25 + x = 80 + x
x = 100°

mr keon spent 5/8 of his salary of
2 416.00 on food,rent,clothes and transport how mush money did he spend
The salary Mr. Keon spent 1510 on food, rent, clothes, and transport.
The term "linear function" in mathematics applies to two different but related ideas: A polynomial function of degree zero or one that has a straight line as its graph is referred to as a linear function in calculus and related fields.
If y is the amount of money Mr. Keon spent on food and clothes and x is Mr. Keon's salary.
Then the linear function for the relation between x and y is:
y = ( 5/8) × (x)
y = (5/8)x
The salary of Mr. Keon is 2416.
Now, Mr. Keon spent 5/8 of his salary on food, rent, clothes, and transport.
Let x be the money she spent.
Then,
x = 5/8 of Mr. Keon's salary
x = ( 5/8 ) × 2416
x = ( 2416 × 5 ) / 8
x = 12080 / 8

find the perimeter or circumference and area of each figure if each unit on the graph measure 1 centimeter. round answers to the nearest tenets, if necessary
The circumference of the circle = 17.8 units
The area of the circle = 25.1 square unit
Given,
the points are A(2,3) and B(4,1)
Formula to get the circumference of a circle = 2πr
Where r = radius of the circle
Radius of the given circle = Distance between the points A(2, 3) and
B(4, 1)
r = √(2 - 4)² + (3 -1)²
r = √(-2)² + (2)²
r = √4+4
r = √8
r = √2(4)
r = 2√2
Therefore the circumference is = 2π(2√2)
= 17.77
≈ 17.8 units
Area of the circle = πr²
= π(2√2)²
= 8π
= 25.13
