A population of 100 frogs has a growth rate of 1.25% each month. At this growth rate,
the function f(x) = 100(1.25)* gives the population in x months. In how many months
will the population first reach 500?
Answer: 7.2 months
Step-by-step explanation:
Hi, to answer this question we have to substitute f(x) =500 in the equation given:
f(x) = 100(1.25)^x
500= 100(1.25)^x
Solving for x (number of months)
500/100 = 1.25^x
5 = 1.25^x
log 5 =log 1.25^x
log 5 =x (log 1.25)
log 5 /log 1.25 =x
x = 7.2 months

Prove that the difference of the squares of 2 consecutive numbers is always the sum of the 2 numbers
Answer:
see explanation
Step-by-step explanation:
let the 2 consecutive numbers be n and n + 1
sum = n + n + 1 = 2n + 1
and
(n + 1)² - n² ← difference of the squares
= n² + 2n + 1 - n²
= 2n + 1 = sum of 2 numbers

What is the value of X
Answer:
x=28
Step-by-step explanation:
The interior angles of a triangle must add to 180 degrees.
Therefore,
x+95+57=180
Add 95 and 57
x+152=180
We are trying to find x. In order to do this, we must get x by itself. 152 is being added to x. The opposite of addition is subtraction. So subtract 152 from both sides.
x+152-152=180-152
x=180-152
x=28
Let’s check our answer. Add all the angles together, to be sure they add to 180 degrees.
x+95+57=180
Substitute 28 for x
28+95+57=180
180=180
The equation above is true, so we know that x is equal to 28.
____________________________________
Hey!!
Solution:
X+95+57=180 (sum of angle in triangle)
or,X+152=180
or,X=180-152
X=28 degree.
The value of X is 28 degree.
Hope it helps..
Good luck on your assignment..

PLZ HELP ON THIS AH its another trigonometry question:
An airplane flies 55 degrees east of north from city A to city B, a distance of 470 miles. Another airplane flies 7 degrees north of east from city A to city C, a distance of 890 miles. What is the distance between cities B and C?
Answer:
523.8 miles
Step-by-step explanation:
The drawing attached represents the question. We create a triangle with the distances from each pair of cities, and we call the distance from B to C by 'd'.
First, we need to find the angle BAC:
55° + BAC + 7° = 90°
BAC = 28°
Then, we can use the law of cosines to find the value of d:
d^2 = 470^2 + 890^2 - 2*470*890*cos(BAC)
d^2 = 470^2 + 890^2 - 2*470*890*0.8829
d^2 = 274365.86
d = 523.8 miles

how long will it take for ball to hit the ground with the equation h=-t^2+10t+22
Answer:
about 11.856 time units
Step-by-step explanation:
We have to assume the equation has something to do with the path of the ball relative to the ground. Perhaps it represents height, with t representing time. The height (h) will be zero for the values of t that satisfy ...
0 = -t^2 +10t +22
Using the quadratic formula, we can find the values of t that satisfy this equation:
t = (-10 ±√(10² -4(-1)(22)))/(2(-1)) = (-10 ±√188)/-2 = 5±√47
The value of h is zero for t ≈ 11.856.
_____
About the quadratic formula
The quadratic formula tells you the solution to ...
ax^2 +bx +c = 0
is given by ...
x = (-b ±√(b^2 -4ac))/(2a)
Matching this form to the given equation, we see a=-1, b=10, c=22. The variable used in the given equation is t, instead of x.
What is the volume of the cylinder shown below?
Answer:
Option A
radius = 13 units
height = 20 units
Volume of the cylinder = πr²h
= π (13)² ×20
=3380π cu. units
The volume of the cylinder will be 3380 π cubic units. Then the correct option is A.
What is the volume of a right circular cylinder?Let r be the radius and h be the height of the cylinder.
Then the volume of the cylinder will be
V = π r²h cubic units
The radius is 13 and height is 20.
Then the volume of the cylinder will be
V = π (13)² x 20
V = 3380 π cubic units
Then the correct option is A.

What is the sum of the interior angles in this shape?
Answer:
540°
Step-by-step explanation:
The sum of all the interior angles in a pentagon with 5 sides is 540°.
Answer:
540°
Step-by-step explanation:
Using the formula for finding the sum of interior angles of polygons
(n-2)×180
Where n is no. Of sides
For pentagon (5 sides) it will be

In a quadrilateral A B C D angle d is
equal to 150° and angle a = angle b=angle c
Eind angle A, angle b, and angle c
Answer:
Step-by-step explanation:
Let ∠A = x
Therefore, ∠A = ∠B = ∠C = x
The sum of all angles of a quadrilateral is 360
∠D + ∠A + ∠B + ∠C =360
150 +x + x + x =360
150 + 3x = 360
3x = 360 - 150
3x = 210
x = 210/3
x = 70
∠A = ∠B = ∠C = x = 70°
At a zoo, youth tickets cost $5 and adult tickets cost $9. A group that purchased x youth tickets and y adult tickets spent $90 on tickets. What is the domain of the relationship
Answer:
0 ≤ x ≤ 18
Step-by-step explanation:
Let 'x' be the number of youth tickets purchased at the zoo and 'y' be the number of adult tickets purchased at the zoo.
At a zoo, youth tickets cost $5 and adult tickets cost $9. A group spent a total of $90 on tickets. We can write as
5x + 9y = 90
to find x we divide both side by 5
x = (90-9y)/5 => 90/5 - 9y/5
x = 18 - 9y/5
The domain of the relationship is the possible set of values of x and y that satisfies the equation. The domain of this relationship is
0 ≤ x ≤ 18
At x = 0, it means only adult tickets were purchased.
At x = 18, it means only youth tickets were purchased.
Answer:
0 ≤ x ≤ 18

Kwame must earn more than 16 1616 gold pieces per day to afford living in the City of Gold. Write an inequality that describes G GG, the number of gold pieces Kwame must earn per day to afford living in the City of Gold.
Answer:
G > 16
Step-by-step explanation:
The expression "more than" 16 gold pieces per day means that the number of gold pieces Kwame earns each day (G) must be greater than 16. In order to represent that as an inequality, we should use the greater-than sign: >.
The inequality that describes the number of gold pieces Kwame must earn per day is G > 16.

(c-d)/5 - 2 = 0
c-6d=0
Given the equations, what is the value of c/d?
PLZ HELP WILL MARK BRAINLIEST
Answer:
On the first equation, which is (c-d)/5 - 2 = 0 Let's start by solving c.
First, you need to add 1/5d to both sides:
1/5 c + -1/5 d - 2 + 1/5 d = 0 + 1/5 d
1/5 c - 2 = 1/5 d
Next, add 2 to both sides:
1/5 c - 2 + 2 = 1/5 d + 2
1/5 c = 1/5 d + 2
Now, divide both sides by 1/5:
1/5 c/ 1/5 = 1/5 d + 2/ 1/5
c = d + 10
so, therefore, your answer is c = d + 10
____________________________________________________________
Now we are going to do the 2nd equation, which is c-6d=0 Lets solve c.
The only thing you need to do is you need to add 6d to both sides:
c − 6d + 6d = 0 + 6d
c = 6d
So, therefore, your answer is c = 6d

What could be the length of the side that
corresponds with AD on the scaled copy of the
quadrilateral?
Choose 3 answers:
A 4 units
B 6.5 units
© 12 units
D 32 units

Answer:
Options (A), (B) and (C)
Step-by-step explanation:
In the given figure,
Length of side AD = 16 units
If this side is scaled by a factor = k
Then the length of the corresponding side will be = 16k
If 0 < k < 1,
Then length of the corresponding side will be less than 16.
