Find the equation of the line through the points (-8,3) and (-4,5).
Answer:
[tex]2y - x = 14[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (-8,3)[/tex]
[tex](x_2,y_2) = (-4,5)[/tex]
Required
The line equation
First, calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{5 - 3}{-4 - (-8)}[/tex]
[tex]m = \frac{2}{4}[/tex]
[tex]m = \frac{1}{2}[/tex]
The equation is then calculated as:
[tex]y = m(x - x_1) + y_1[/tex]
[tex]y = \frac{1}{2}(x - (-8)) +3[/tex]
[tex]y = \frac{1}{2}(x +8) +3[/tex]
Open bracket
[tex]y = \frac{1}{2}x +4 +3[/tex]
[tex]y = \frac{1}{2}x +7[/tex]
Multiply through by 2
[tex]2y = x + 14[/tex]
[tex]2y - x = 14[/tex]
Need the answer been stuck on this
Answer:
19 cm³
Step-by-step explanation:
The figure cam be decomposed into two cuboid.
✔️Dimension of cuboid 1:
L = 2 cm
W = 1 cm
H = 8 - 3 = 5 cm
Volume = L * W * H
Volume = 2*1*5 = 10 cm³
✔️Dimension of cuboid 2:
L = 3 cm
W = 1 cm
H = 3 cm
Volume = L*W*H = 3*1*3
Volume = 9 cm³
✅Volume of the irregular figure = 10 + 9 = 19 cm³

The population of a city has been increasing by 2% annually. In 2000, the population was 315,000. Predict the population of the city in 2020. Round your answer to the nearest thousand.
Answer:
In 2020 there will be 468,073 people.
Step-by-step explanation:
Giving the following information:
Growth rate (g)= 2% = 0.02
Population 2,000= 315,000
Number of periods (n)= 20 years
To calculate the population in 2020, we need to use the following formula:
FV= PV*(1+g)^n
FV= 315,000*(1.02^20)
FV= 468,073
In 2020 there will be 468,073 people.

Find the area of this figure around your answer to the nearest 100. use 3.14 to approximate 3.14 as pi
Answer:
Area = 49.12 ft²
Step-by-step explanation:
The area of the figure = area of triangle + area of half of a circle
= ½*bh + ½(πr²)
b = 6 ft
h = 8 ft
r = ½ of 8 ft = 4 ft
π = 3.14
Plug in the values
Area of the figure = ½*6*8 + ½(3.14*4²)
Area = 24 + 25.12
Area = 49.12 ft²
Answer:
49.12

If lines r and s are parallel, what would be the measurement of angle 6 if angle 1 was 2x+4 and angle 2 was 6x+8?
Answer: 134
Step-by-step explanation:
Angle 1 and 2 are supplementary and Angle 2 is congruent to Angle 6
Thus, first solve for x
8x+12=180
x = 21
Then solve for angle 2 which is congruent to angle 6
6(21) + 8 = 134

Which polynomial represents the difference below? 10x^8 + 11x^6 - 2x + 5 - (8x8 + 6x7 - 5)
Answer:
[tex]2x^8-6x^7+11x^6-2x+10[/tex]
Step-by-step explanation:
To find: [tex]10x^8+11x^6-2x+5-(8x^8+6x^7-5)[/tex]
Solution:
Like terms refer to terms with same variables and same powers.
Two like terms can be added or subtracted.
Consider the following expression:
[tex]10x^8+11x^6-2x+5-(8x^8+6x^7-5)=10x^8+11x^6-2x+5-8x^8-6x^7+5\\=(10-8)x^8-6x^7+11x^6-2x+(5+5)\\=2x^8-6x^7+11x^6-2x+10[/tex]
(Here, like terms are added or subtracted)
Find the slope of BG, and HL using the coordinates; B(-4, 3), G(-2, 4), H(1, -2), L(-1, -3). then determine if the lines are parallel.

Every morning, Jim goes for a morning walk. His normal walking speed is 3 1/2 km per hour, and he walks a total distance of 10 km every day. How much time does he take to cover one km?
Hint 1 Notice the unit of Speed.
Hint 2 Can you figure out the distance covered in one hour
Answer:
Jim's walking speed = 312kmph
covered distance = 10km
time taken for one hour = ?
we know that: Distance =speed × time
=>Time = Distance/speed
=> Time = 10/312=5/156 hours
= Time = (5×60)/156=300/156=75/39=1.9 minutes
