Answer:
432 square centimeters
Step-by-step explanation:
Given :
The circumference of a hub cap is = 73.66 cm
The circumference of a circle is given as = 2πr, where r is the radius of the circular hubcap.
So , 2πr = 73.66
⇒ [tex]$r=\frac{73.66}{2 \times \pi}$[/tex]
⇒ [tex]$r=\frac{73.66}{2 \times 3.14}$[/tex] (Using, π = 3.14)
⇒ r = 11.73 cm
Therefore the area of the hub cap is given by A = [tex]$\pi r^2$[/tex]
A = [tex]$3.14 \times 11.73 \times 11.73$[/tex]
= 432 [tex]$cm^2$[/tex]
If the circumference of the hubcap were smaller, the area of the hubcap would be smaller too, since the circumference of the hubcap is proportional to the radius which is proportional to the area too.
Find the area for this problem
Answer:
494 cm^2
Step-by-step explanation:
Find area od the rectangle:
14 x 26 = 364
Find area of the triangle:
10 x 26 = 260
260/2 = 130
Add the areas together:
364 + 130 = 494

What is the equation for a line with a slope of
4/5 and a y-intercept of (0,7)?
Answer:
y = 4/5x + 7
Step-by-step explanation:
Use the slope intercept form, y = mx + b, where m is the slope and b is the y intercept
Plug in the slope and y intercept value of 7 to create the equation
y = mx + b
y = 4/5x + 7
So, the equation of the line is y = 4/5x + 7

Answer:
-23
Step-by-step explanation:
Using the absolute rule,
[tex]\left|-a\right|=a[/tex].
Therefore,
[tex]-|-23|=-23[/tex]
(It becomes 23 first, but then you stick the negative sign after)
André e Bruno foram a uma lanchonete e compraram lanches e sorvetes iguais. Bruno comprou 2 lanches e 1 sorvete e pagou R$21,00. Já André comprou 3 lanches e 2 sorvetes, pagando R$33,00. Qual era o preço, em reais, de cada lanche que André e Bruno compraram nessa lanchonete? R$5,00. R$9,00. R$10,50. R$10,70.
Answer:
the price of each snack be R $9.00
Step-by-step explanation:
Let us assume the snack be x
And, the ice cream be y
Now according to the question
2x + y = $21
And,
3x + 2y = $33
Now multiply by 2 in equation 1
So,
4x + 2y = $42
3x + 2y = $33
x = 9
Hence, the price of each snack be R $9.00

Step-by-step explanation:
Answer: 5(5x+11)
Step-by-step explanation:
What multiplies to be 25x, 5 and 5 x is the answer, 5 goes on the left because of the next step which is what times what equals 55. 5 times 11 equals 55. So 11 is on the top while 5 is on the left,

Put the quadratic equation y=4x^2-24x+5 into vertex form by completing the square then state the coordinates of the vertex.
Answer:
(3, -31)
Step-by-step explanation:
Factor 4 out of the first two terms:
y=4x^2-24x+5 becomes y=4(x^2 - 6x) +5
Next, complete the square of (x^2 - 6x): It is x^2 - 6x + 9 - 9
Insert this into y=4(x^2 - 6x) +5 in place of x^2 - 6x:
y=4(x^2 - 6x) +5 => y=4(x^2 - 6x + 9 - 9) +5, or
y=4( (x - 3)^2 - 9 ) + 5, or
y = 4(x - 3)^2 - 36 + 5, or:
y = 4(x - 3)^2 - 31
Compare this to: y = a(x - h)^2 + k
We see that the coordinates of the vertex (h, k) are (3, -31), and that a = 4.

Jillian and Josie are trying to find the value of the function, 8x^4-12x^3+3x^2-7x+4 at x=-1. Jillian says the only way to find the answer is to plug in -1. Josie says, no, there is another way. Who is right? Justify your answer.
Answer:
Josie is correct.
Step-by-step explanation:
There are other ways of finding the value of the function at x = 1.
For example, one way would be graphing or using a graphing device to graph the function. Once graphed, looking for the y-value where x = 1 would also provide the answer.

The scatter plot shows the amount of sleep Aria got the night before a test and her test scores. Use the y-intercept, (0, 62), and the point (6, 80) from the line on the scatter plot. What is the equation of the trend line? (*Note: Enter your response as an equation in y=mx+b form. Enter no spaces & use only lower-case letters. Ex: y=10x+5 ) *
Answer:
y = 3x + 62
Step-by-step explanation:
Trend line equation in the form :
y = mx + b
m = slope
b = intercept
Using the points :
(0, 62) ; (6, 80)
Slope, m = Rise / Run = (y2-y1) / (x2 - x1)
y2 = 80 ; y1= 62 ; x2 = 6 ; x1 = 0
m = (80 - 62) / (6 - 0)
m = 18 / 6
m = 3
Intercept, b = value of y when x = 0
(0, 62) ; hence, b = 62
y = 3x + b
y = 3x + 62
