Answers
Answer:
Step-by-step explanation:
To simplify the expression:
4(3x+2) - 2
The first step is to open the brackets
= 4 * 3x + 4* 2 - 2
= 12x + 8 - 2
= 12x - 6
Factor out the above expression, we get;
= 6(2x - 1)
To factor out the expression:
20b - 16
the factor that can be divided by 20 and 16 without remainder is 4;
So, we have:
= 4(5b - 4)

FIND THE AREA OF THE SEGMENT AYB. IF RADIUS OF THE CIRCLE IS 21cm AND ANGLE AOB= 120 DEGREE ( use pie= 22/7)
PLZ answer very urgent
Answers
Answer:
The area of the segment AYB is 271.0413985 cm²
Step-by-step explanation:
The rule of the area of a sector is A = [tex]\frac{\alpha }{360}[/tex] × π r², where
α is the central angle of the sectorr is the radius of the circleThe area of a triangle is A = [tex]\frac{1}{2}[/tex] × s1 × s2 × sinФ
s1 and s2 are two sides of the triangleФ is the included angle between s1 and s2∵ Area of the segment AYB = Area the sector AOB - Area ΔAOB
∵ The radius of the circle is 21 cm
∴ r = 21 cm
∵ The central angle of the sector is 120°
∴ α = 120°
∵ π = [tex]\frac{22}{7}[/tex]
→ Substitute them in the rule of the area of the sector to find it
∵ Area sector AOB = [tex]\frac{120}{360}[/tex] × [tex]\frac{22}{7}[/tex] × (21)²
∴ Area of sector AOB = 462 cm²
∵ OA and OB are the radii of the circle
∴ s1 = OA and s2 = OB
∴ s1 = s2 = 21 cm
∵ The angle included between them is 120°
∴ Ф = 120°
→ Substitute them in the rule of the area of the triangle to find it
∵ Area of the Δ = [tex]\frac{1}{2}[/tex] × 21 × 21 × sin(120)
∴ Area of the Δ = 110.25√3 cm²
∵ Area of the segment AYB = Area the sector AOB - Area ΔAOB
∴ Area of the segment AYB = 462 - 110.25√3
∴ Area of the segment AYB = 271.0413985 cm²

the graph shows the height of a thrown ball x seconds after it is thrown. based on the situation, are there any constraints on the domain of the function
Answers
Answer:
The time can not be negative. Thus, the domain of the given graph function must have the interval [0, ∞].
In other words, t ≥ 0.
Step-by-step explanation:
We know that the domain of a function is the set of input or argument values for which the function is real and is defined.
Given that the graph is showing the height of a thrown ball x seconds after it is thrown.
We must check that the time can not be negative. Thus, the domain of the given graph function must have the interval [0, ∞].
In other words, t ≥ 0.

Step-by-step explanation:

The answers to each part is given below.
What is percentage?In mathematics →
a percentage is a number or ratio expressed as a fraction of 100.it is often denoted using the percent sign "%".Given is that you buy a watch for $60.
{a} -Total cost of watch -
{C} = ${60 + (6% of 60)}
{C} = ${60 + (6/100 x 60)}
{C} = $(60 + 3.6}
{C} = $63.6
{b} -New sale price -
{D} = 60 - (15% of 60)
{D} = 60 - (15/100 x 60)
{D} = 60 - 9
{D} = $51
{c} -Total cost of watch including tax -
{CT} = 51 + (6% of 51)
{CT} = 51 + 3.06
{CT} = 54.06

write the linear equation from the given information in slope intercept form (-1,3); slope=-3
Answers
Answer:
y = -3xStep-by-step explanation:
The standard expression of equation of a line in slope-intercept form is expressed as;
y = mx+c
m is the slope
c is the intercept
Given
slope m = -3
Point (x, y) = (-1, 3)
x = -1 and y = 3
Get the intercept
To get the intercept c, we will substitute the given values into the equation above to have;
y = mx+c
3 = -3(-1)+c
3 = 3 + c
c = 3-3
c = 0
Substitute m = -3 and c = 0 into the equation above;
y = mx+c
y = -3x+0
y = -3x
Hence the required linear equation is y = -3x
On a town map, each unit of the coordinate plane represents 1 mile. Three branches of a bank are located at A(−3, 1), B(2, 3), and C(4, −1). A bank employee drives from Branch A to Branch B and then drives halfway to Branch C before getting stuck in traffic. What is the minimum total distance the employee may have driven before getting stuck in traffic? Round to the nearest tenth of a mile if necessary.
The minimum total distance the employee may have driven before getting stuck in traffic is
miles.
Answers
Answer:
7.6 miles
Step-by-step explanation:
Given the coordinate points :
A(−3, 1), B(2, 3), and C(4, −1)
Distance (d) between A and B:
x1 = - 3 ; x2 = 2 ; y1 = 1 ; y2 = 3
d = √(x2 - x1)² + (y2 - y1)²
d = √(2 - (-3))² + (3 - 1)²
d = √25 + 4
d = 5.385 miles
BC :
d = √(x2 - x1)² + (y2 - y1)²
d = √(4 - 2)² + (-1 - 3)²
d = √2² + (-4²)
d = √4 + 16
d2 = 4.4721359 miles
(1/2) of d2 = 1/2 * 4.4721359 = 2.236 miles
Total distance = (5.385 + 2.236) miles
Total distance driven before getting stuck in traffic = 7.6 miles
Jordan is using a six-sided number cube to predict whether people shopping in the mall arrive by car or by bus. Based on data gathered in a survey, Jordan decided that a roll of 1 or 2 would represent a person having taken the bus, while any other outcome would represent arriving by car.
Answers
Answer:
1/3 of the people come by bus
2/3 of the people come by car
Step-by-step explanation:
The probability of getting a 1 or 2 by rolling the six sided number cube is
P ( 1or 2) = 1/6 + 1/6= 2/6= 1/3
The total probability is always 1 so to get the probability of people arriving by car we subtract the probability of people arriving by bus from 1.
P ( not getting 1 or 2) = 1- P ( 1or 2)
= 1- 1/3= 2/3
The probability of people arriving by bus is 1/3 and the probability of people arriving by car is 2/6or 2/3.
