Answer:
y = 9/2 (fraction)
Step-by-step explanation:
y = mx+c
m = slope
c =y -intercept
Therefore, the required equation is:
y = 2x + c
Putting the point (0,4) in it as it lies on a line, we get:
4 = -1/2 + c
Therefore:
c = 9/2
So, y = 9/2

(Help please, Subject: Properties of exponents) Organisms A and B start out with the same population size.
Organism A's population doubles every day. After 5 days, the population stops
growing and a virus cuts it in half every day for 3 days.
Organism B's population grows at the same rate but is not infected with the virus.
After 8 days, how much larger is organism B's population than organism A's
population? Answer the questions td find out.
1. By what factor does organism A's population grow in the first five days? Express
your answer as an exponential expression.
Write your answer in the space below.
Answer:
1. 252N = ( x x )N
2. Factor =
Step-by-step explanation:
Let the starting population size for organisms A and B be represented by N.
For organism A;
Day 0: N
Day 1: 2N
Day 2: N
Day 3: N
Day 4: N
Day 5: N
Day 6: N
Day 7: N
Day 8: N
For organism B;
Day 0: N
Day 1: 2N
Day 2: N
Day 3: N
Day 4: N
Day 5: N
Day 6: N
Day 7: N
Day 8: N
1. After the eight days, organism B's population is larger than organism A's population by;
N - N = 256N - 4N
= 252N
= ( x x )N
2. Organism A's population grows by .
Pls answer it urgent pls I couldn't find answers for this anywhere Pls give answer with formulas and steps 4/9 ÷ -5/7
Answer:
-28/45
Step-by-step explanation:
Here, we want to find the result of a division
What we have to do here is to flip the fraction on the right hand side , then change the sign from division to multiplication
We have this as;
4/9 * -7/5
= -28/45
solve for a, geometry work
Answer:
a = 45 degrees
Step-by-step explanation:
Since both angles are a, they are equal to each other
Also, we know that the right angle means it measures 90 degrees
So, (180-90)/2 = a
a = 45 degrees

How do you find the base in the Pythagorean theorem, c=18, a=9, what is b?
Answer:
b = 15.59
Step-by-step explanation:
a^2 + b^2 = c^2
9^2 + b^2 = 18^2
81 + b^2 = 324
-81 -81
b^2 = 243
b = 15.59
Pythagorean Theorem -
[tex]a^{2} + b^{2} = c^{2} [/tex]
1 - Input the values!
[tex] 9^{2} + x^{2} = 18^{2} [/tex]
2. Find the exponents!
[tex]81 + x^{2} = 324[/tex]
3. Multi step Equations!
[tex]81 - 81 = 0 \\ 324 - 81 = 243[/tex]
4. Use square roots to find x!
[tex]x = \sqrt{243}[/tex]
Answer: X=The Square Root Of 243

If the sidewall of a cubic structure have length 7m , then find the total surface area.
is this jhit right?
Answer:
Surface area of the cube = 294 m²
Step-by-step explanation:
Sidewall of a cube measures in length = 7 m
Formula for the surface area of a cube = Sum of the areas of all six sides of the cube
= 6 × (Side)²
= 6 × (7)²
= 6 × 49
= 294 m²
Therefore, surface area of the cube is 294 m².

So when finding probabilities we want to find how many even numbers there are and divide that by the amount of numbers
we see that there are 3 even number ( 2, 16 and 8) and there are 8 numbers in total
So in one spin the probability of it landing on an even number is 3/8
Now to find the probability it will land on an even number in 120 spin we multiply 3/8 and 120
[tex]\frac{3}{8} x 120=45[/tex]
So the reasonable prediction of it landing on an even number out of 120 spins is 45

can anyone help? im a lil lost
Answer:
So they just want you to solve the equation if x= -4
d(-4) = -(-4) + -4
y = 4 - 4
The solution would be 0.
Isaac and Albert spot a hot air balloon flying at a low altitude. They decide to calculate its height by standing 400 feet apart on a level surface and measuring the angle of elevation to the balloon. From
Albert, the balloon was at an angle of elevation of 62°and from Issac its was 48º. Determine the height of
the balloon above the ground to the nearest foot.
Answer:
144 feet to nearest foot.
Step-by-step explanation:
Let the distance between Albert and the point on the ground that the balloon is directly above be x feet Then for Isaac the distance is 400 - x feet
So we have 2 right angled triangles and:
tan 62 = h/x
tan 48 = h / (400- x) where h is the height of the balloon.
From the first equation x = h / tan 62 so plugging this into the second one:
tan 48 = h / ( 400 - h/tan 62)
h = 400 tan 48 - h tan 48 tan 62
h + h tan 48 tan 62 = 400 tan 48
h ( 1 + tan48 tan62) = 400 tan48
h = 400 tan 48 / (1 + tan 48 tan 62)
= 143.8 feet.
What is the explicit rule for the sequence:
11, 22, 44, 88...
Answer:
Geometric Progression is the explicit rule for the given sequence: 11, 22, 44, 88...
First term (a) = 11
Common ratio (r) = 22/11 = 44/22 = 88/44 = 2
Formula used in Geometric Progression is :---
[tex]\boxed{a_n = a {r}^{(n - 1)}}✓\\ [/tex]
where, 'n' is the required term

a)5 students
C)25 students
B)14 students
D)30 students
Answer:
D
Step-by-step explanation:
the number of students who plays sport are 1/7 of 35 that means that there are 35/7 students play sport so there is only 5 of 35 students play sport
so number of students thatn dont play sport are 35 - 5 = 30

Total interior angle of pentagon: 540 degrees
(3x + 23) + (9x - 6) + 95 + 90 + (7x - 4) = 540
19x + 23 - 6 + 95 + 90 - 4 = 540
19x + 17 + 95 + 90 - 4 = 540
19x + 13 + 185 = 540
19x + 198 = 540
19x = 342
x = 18
