Georgina has a total of $5000 invested in a savings account that receives 0.6% APY and a CD that receives 0.9% APY. How much does she have invested in each account if her total annual interest earned is $37.50?

The percentage of students that use other means to travel school is  24%

Percentage is the ratio of  the number for which you want to find  percentage to the total number with which you want to compare or out of and multiply this ratio with 100.

percentage = (part / whole) ×100

Given that a school has 825 total students.

Percentage of students travelling by car = 20%

Percentage of students travelling by bus = 48%

Percentage of students travelling by bicycle = 8%

Number of students travelling by car = 20% of 825 = (20/100)×825 = 165

Number of students travelling by bus = 48% of 825

= (48/100)×825 = 396

Number of students travelling by bus  = 8% of 825 = (8/100)×825 = 66

Number of students travelling by other means = 825-165-396-66 = 198

Therefore, the Percentage of students travelling by other means  = (198/825) ×100 = 24%

Answer:

D

Step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 1) and (x₂, y₂ ) = (1, 7) ← 2 points on the line

m = [tex]\frac{7-1}{1-(-2)}[/tex] = [tex]\frac{6}{1+2}[/tex] = [tex]\frac{6}{3}[/tex] = 2

use either of the 2 points on the line

using (- 2, 1 ) , then

y - 1 = 2(x - (- 2) ) , that is

y - 1 = 2(x + 2) ← equation in point- slope form

Answer:

Step-by-step explanation:

slope = rise/run = (difference in y)/(difference in x)

First, we find a difference in y.

Subtract any two values of y.

For example: 35 - 14 = 21

Now we find the corresponding difference in x.

Now subtract the x values corresponding to those y values in the same order.

-1 in x corresponds to 35 in y.

-4 in x corresponds to 14 in y.

That means your difference in x is the subtraction -1 - (-4) = -1 + 4 = 3

The difference in y is 21.

The difference in x is 3.

slope = (difference in y)/(difference in x) = 21/3 = 7

The set of the value for which the curve and line have no common point are is k ∈ (0 , 4).

The value for which the line is a tangent is k = 4.

The coordinates of the point where the line touches the curves is point of tangency = ( 1/2 , 2).

What is tangent?

Tangents in geometry are lines or planes that contact curves or surfaces at points where they are closer to the curve than any other lines or planes drawn through those points.

Given equations in the question:

y = kx² + 1  

y = kx

Equating y

kx² + 1   = kx

kx² -kx  + 1 =  0

This is Quadratic equation is of the form ax²+bx+c=0  where a  , b and c are real also  a≠0.

D =  b²-4ac is called discriminant.

and we know that,

D >0 roots are real and distinct

D =0 roots are real and equal

D < 0 roots are imaginary ( not real ) and different

For no common solution  D < 0

For tangent  D = 0

so,

kx² -kx  + 1 =  0

D = (-k)² - 4k  = k² - 4k = k(k - 4)

k(k - 4) < 0

if  0 < k < 4

Hence values of k for which the curve and the line have no common points is k ∈ (0 , 4).

for tangent

k(k - 4)  = 0

k is non zero

Hence k = 4

After putting the value of k, given equations are:

y = 4x² + 1  

y = 4x

solving these equations to get value of x and y:

4x² + 1   = 4x

4x² - 4x + 1 = 0

(2x - 1)² = 0

x = 1/2

y = 2

Point of tangency = ( 1/2 , 2)

The equation which is useful to find the amount in gallons of water to the number of minutes since filling started is 25 + 11x therefore, it takes 5 minutes to have 80 gallons of water.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

The amount of water initially in the trough = 25 gallons.

The rate of adding water = 11 gallons per minute

Therefore, the total amount (A) of water in x minutes will be,

A = 25 + 11x

The number of minutes to have 80 gallons of water is,

80 = 25 + 11x

11x = 55

x = 5 minutes.

They are similar because they have the same slope the equation is

y = -2/3x + 531

What is in slope-intercept form?

changing 2x+3y=1470 to slope intercept form is solving for y

minus 2x both sides and divide by 3

y = -2/3x + 490

the slope is -2/3

the y intercept is y=490 or the point (0,490)

to graph it, I would start at the origin and go up 490 units on the y axis and put a point there

then go -2 units up (2 down) and 3 to the right and put a point there

then connect the 2 points with a line

in function notation, replace y with f(x) to get

Assume √2 is rational, so

√2 = p/q

for some relatively prime integers p,q - meaning we can't reduce p/q any further - and q ≠ 0.

Then

p = √2 q

and squaring both sides gives

p² = 2q²

This tells us that p² is even, so 2 divides p². But if 2 divides p², it must also divide p, since p is a square number. So p = 2r for some integer r, and we have

(2r)² = 2q²

4r² = 2q²

2r² = q²

We're in the same situation as before - 2 divides q², so 2 divides q. Both p and q are thus divisible by 2, but this contradicts our assumption that p and q are relatively prime, which means √2 cannot be expressed as a rational number p/q. Therefore √2 is irrational.

What you've written in your proof is technically correct, but it doesn't help in the irrationality proof.

The value of x is approximately 5.4 when x^3 -10x = 100

How to solve the equation?

The equation is given as:

x^3 -10x = 100

Using trial by error, we keep testing for the value of x that is true for x^3 -10x = 100

After several attempts, we have:

x = 5.4 (approximately)

Substitute 5.4 for x in x^3 -10x = 100

5.4^3 -10 * 5.4 = 100

Evaluate

103.5 = 100

The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.

It is known that x% of something y is given as,

x% of y = (x/100)y

Given that discount of 20% of y

20% of y = (20/100)y

20% of y = 0.20y

Now the final price = initial price - discount

Final price (P) = y - 0.20y

She next walks 1.2 meters to the opposite side of the mirror, where she can easily see the top of the goalpost depicted in the X. Her partner determines that the distance between her eyes and the ground is 1.35 meters.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

As per the given information, the figure has been attached below.

Set up the proportional and solve for x

1.2 : 13.45 = 1.35 : x
