What do the a b and c stand for in the pythagorean theorem?
Answer:
A, B, and C are labeled for each side of a right triangle.
Step-by-step explanation:
A and B are used to label the legs while C is used to label the hypotenuse(AKA the long side of a right triangle and the side opposite of the 90° angle.) The B side is the opposite side of the hypotenuse or the side C. The A is the bottom leg that is in between sides B and C.
One customer paid $12 for 14 postcards and 5 large envelopes. Another customer paid $24.80 for 10 postcards and 15 large envelopes. What was the cost in dollars of each large envelope?
Answer:
$1.42
Step-by-step explanation:
Since, The first customer paid $12 for 14 postcards and 5 large envelopes.
That is, 14 x + 5 y = 12 ------ (1)
And, The second customer paid $24.80 for 10 postcards and 15 large envelopes.
That is, 10 x + 15 y = 24.80 -------(2)
3 × equation (1),
We get, 42 x + 15 y = 36 ---------(3)
Equation (3) - Equation (2)
32 x = 11.20
⇒ x = 11.20/32
⇒ x = 0.35
By putting the value of x in equation (1),
We get, 14 × 0.35 + 5 y = 12
⇒ 4.9 + 5 y = 12
⇒ 5 y = 7.1
⇒ y = 1.42
Thus, the cost of one postcard = $ 0.35
And, the cost of each large envelope = $ 1.42

The position of an object at time t is given by s(t) = -9 - 3t. Find the instantaneous velocity (by using the limit) at t = 8 by finding the derivative
Answer: [tex]v=-3[/tex]
Step-by-step explanation:
Given
The position of a particle is [tex]s(t)=-9-3t[/tex]
Velocity is given by the derivative of position with respect to time
[tex]\Rightarrow v=\dfrac{ds}{dt}\\\Rightarrow v=-3[/tex]
So, velocity is constant at any point in time.
At t=8, it is [tex]v=-3[/tex]

A golf ball is hit in not the air represented by the equation y= -3x^2+18x+45. The maximum height the ball will reach is____ feet
Answer:
72 ft
Step-by-step explanation:
Here, we want to get the maximum height the ball will reach
the maximum height the ball will reach is equal to the y-coordinate of the vertex of the equation
So we need firstly, the vertex of the given quadratic equation
The vertex can be obtained by the use of plot of the graph
By doing this, we have it that the vertex is at the point (3,72)
Thus, we can conclude that the maximum height the ball can reach is 72 ft

The length of a rectangle is 3 inches longer than twice its width, where w is the width of th
rectangle. The area of the rectangle is 90 square inches. *
Answer:
6 in and 15 inStep-by-step explanation:
Given:
l = 2w + 3A = 90 in²w = ?l = ?Area formula:
A = lwSubstitute values and solve for w:
(2w+3)w = 902w² + 3w = 902w² + 3w - 90 = 0w = (-3 ± [tex]\sqrt{3^2 - 4*2*(-90)}[/tex])/2*2w = (-3 ± √729)/4w = (-3 ± 27)/4w = 6 (positive root only)The width is 6 in, find the length:
l = 2*6 + 3 = 15 inwidth be x
Length be 2x+3Now
area=Length×Breadthx(2x+3)=902x²+3x=902x²+3x-90=0On solving we will get
x=6[Take positive]Now
Length=2(6)=3=15in

Rewrite the quadratic expression in faceted format: f left parenthesis x right parenthesis equals negative x squared minus 4 x plus 21
Answer:
[tex]f(x)=-x^2-4x+21[/tex]
Step-by-step explanation:
The given equation is :
f left parenthesis x right parenthesis equals negative x squared minus 4 x plus 21.
We need to rewrite this equation in faceted format.
The general form of a quadratic equation is given by :
[tex]f(x)=ax^2+bx+c[/tex]
We have,
a = -1, b = -4 and c = 21
Substitute all the values,
[tex]f(x)=-x^2-4x+21[/tex]
So, the required equation is equal to [tex]f(x)=-x^2-4x+21[/tex].
Why do equivalent ratios form a straight line when graphed?
Answer:
The y-values of equivalent ratios increase at the same rate as their x-values. The vertical distance between points is constant, and the horizontal distance between points is constant. This forms a straight line.

Answer:
B) 4.52cm²
Step-by-step explanation:
If the shaded area represents 1/4 the area of a circle, then given a diameter of 4.8cm, the area of the entire circle is A=πr²=π(4.8/2)²=π(2.4)²=5.76π=5.76(3.14)=18.0864cm²
Since we're finding 1/4 the area of the circle, then 1/4*18.0864=4.5216cm²
So the shaded area is 4.5216cm², making the closest choice B) 4.52cm²
please help me out, thank youuu !
The image shows a circle centered at point O. Angle AOB measures 50 degrees. What is the measure of angle ACB?
Answer:
b) ∠ACB = 25 degrees
Step-by-step explanation:
arc BA = 50° because central angle AOB = 50°
∠ACB is inscribed angle of 50°, so it is (1/2)(50) = 25°
The measure of angle ACB is 25°. The correct option is a. 25 degrees
Circle GeometryFrom the question, we are to determine the measure of angle ACB
From one of the Circle theorems, we have that
The angle at the center of a circle is twice the angle at any part of the circumference.
That is, in the given circle
<AOB = 2 × <ACB
Then,
<ACB = 1/2(<AOB)
<ACB = 1/2 × 50°
<ACB = 25°
Hence, the measure of angle ACB is 25°. The correct option is a. 25 degrees
