Step-by-step explanation:
At an ice cream shop, the profit, P(c), is modeled by the function ;
P(c) = 0.87c. An appropriate domain for this function is an integer [tex]\geq[/tex] 0.
What is a function?A function is defined as a relation between the set of inputs having exactly one output each.
All the points (and only those points) which lie on the graph of the function satisfy its equation.
Thus, if a point lies on the graph of a function, then it must also satisfy the function.

4. You sketch a right triangle that has a
hypotenuse of 12 centimeters, and one leg
that is 7 centimeters. How many centimeters
Is the other leg?
Answers
Answer:
√95 cm
Step-by-step explanation:
To solve, you need to use the pythagorean theorem, or a^2 + b^2 = c^2
The hypotenuse is the c and let one leg be b. You can write:
a^2 + 7^2 = 12^2
a^2 + 49 = 144
Now, you need to solve for a:
a^2 = 144 - 49
a^2 = 95
a = √95 cm, or about 9.75cm

What is Theorem?A statement that has been proven true or that can be proven is known as a theorem in mathematics. A logical argument is used to prove a theorem by using the deductive system's inference rules to show that the theorem follows logically from the axioms and other theorems that have already been proven.
Guessing and Conjecture is just striking some ideas without any definite conclusion.
A claim that is accepted as true without evidence, also referred to as an axiom. Lemmas and theorems are deduced from postulates, which serve as their fundamental building block.

For the function above is the discriminate, positive, negative, or zero?
Answers
Answer:
0
Step-by-step explanation:
When there is one x-intercept, the discriminant is zero.
__
The discriminant is used to compute the difference between the roots. When it is positive, the real roots are different, so there are two x-intercepts.
When the discriminant is zero, there is no difference between the roots, so there is one x-intercept (as here).
When the discriminant is negative, there are no x-intercepts and the two roots are complex.
What is the equation, in slope-intercept form, of the line that is perpendicular to the line
y-4 = (x – 6) and passes through the point (-2, -2)?
Answers
Answer:
y=x
Step-by-step explanation:
slope intercept form:
y= mx +c, where m is the gradient and c is the y-intercept.
Let's rewrite the given equation in the form of y=mx+c, so that we can determine the gradient of the line.
y-4= x-6
y= x -6 +4
y= x -2
Thus, the gradient of the given line is 1.
the product of the gradients of perpendicular lines is -1.
(gradient of line)(1)= -1
gradient of line= 1
Thus, m=1.
y= 1x +c
y= x +c
To find c, substitute a coordinate.
When x= -2, y= -2,
-2= -2 +c
c= -2 +2
c=0.
Thus the equation of the line is y=x.

Answer:
A coordinate plane showing Falling Leaf, Time in seconds on the x-axis and Height in feet on the y-axis. A line is passing through (0, 12), (8, 10), and (16, 8).
Step-by-step explanation:
The y-intercept of the graph is the height of the leaf at the beginning, that is, 12 ft. This means that point (0, 12) is on the line.
The leaf falls to the ground at a rate of 0.25 feet per second, this means that after 8 seconds, the leaf travel 8*0.25 = 2 ft. Given that it started at 12 ft, its height is 12 - 2 = 10 ft. In other words, the point (8, 10) is on the line. Similarly, its height after 16 seconds is 12 - 16*0.25 = 8 ft, that is, the point (16, 8) is on the line.

Angle COD is 60 degrees

Because angle DOE is vertically opposite to angle boa, it is also 40 degrees. we know that angle DOF is 120, so angle FOE is 120-40 = 80 degree, and angle BOC is vertically opposite do it is 80 degrees.
since angle COD lies on a straight line it adds up to 180 degrees, so 180- 120 = 60 degrees

Answer:
D or x≥4
Step-by-step explanation:
The number has to be 4, since the dot lies on it, so that excludes A and B.
It is greater, because the arrow is pointing right instead of left.
Since the circle is closed, then it means that it includes 4.
So, C would not be the answer, because it is read as " x is greater than 4"
it should be D, which is " x is greater than or equal to 4" (since the circle is closed).
Thus, D is the answer

In the diagram, point O is the center of the circle and m∠ADB = 43°. If m∠AOB = m∠BOC, what is m∠BDC?
Answers
Answer:
B - 43
Step-by-step explanation:
The required measure of the angle m∠BDC is 43°.
Given that,
In the diagram, point O is the center of the circle, and m∠ADB = 43°. If m∠AOB = m∠BOC, what is m∠BDC is to be determined.
The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
where h, k is the coordinate of the center of the circle on the coordinate plane and r is the radius of the circle.
Property of circle -
"The angle subtended by an arc of the circle to the center point of the circle is double the angle subtended by the same arc on any point the circumference of the circle."
So,
From the above property,
Angle subtended by Arc AB at center or m∠AOB is 2 * 43 = 86°
From given m∠AOB = m∠BOC,
Implies
m∠BOC = 86°
Angel subtended by arc BC at D is m∠BDC = m∠BOC /2
= 86 /2
= 43°
Thus, the required measure of the angle m∠BDC is 43°.

Luke is flying a kite and realizes that 400 feet of string are out. The angle of the stream with the ground is 50°. How high is Luke’s kite above the ground
Answers
Answer:
Luke's kite is 306.4 feet high above the ground
Step-by-step explanation:
To find the height of Luke's kite above the ground, we will follow the steps below:
We can solve the problem using trigonometric ratio;
that is;
SOH CAH TOA
sinФ = opposite/hypotenuse
cosФ= adjacent/hypotenuse
tanФ=opposite/adjacent
From the diagram below:
opposite = x where x represents the height of Luke's kite above the ground
hypotenuse = 400
Ф = 50
The best trig ratio to use is sin
sinФ = opposite / hypotenuse
sin 50° = [tex]\frac{X}{400}[/tex]
cross-multiply
x = 400 sin 50°
x≈306 .4 feet
Luke's kite is 306.4 feet high above the ground
