Write a quadratic equation with 7 and as its roots. Write the equation in the form ax^2+ bx + C = 0,
where a, b, and c are integers.

Answers

Answer 1
x^2 - 37/5x + 14/5
.
Answer 2

The equation in the form ax² + bx + c of the quadratic equation with 7 and 2/5 as it root is x² - 33 / 5 x + 14 / 5

The root of the quadratic equation are 7 and 2/5 .

The equation should be written in the form

ax² + bx + c

where

a, b and c are integers.

Therefore,

x - (7) and x - 2/5

(x - 7)(x - 2/5)

open the bracket

x² - 2/5x - 7x + 14 / 5

x² - 33 / 5 x + 14 / 5

where

a = 1

b = -33 / 5

c = 14 / 5

Answer:

20

Step-by-step explanation:

The slope formula is y= mx+b

m= slope

x= x (the variable)

b= y-intercept

Li deposited $17,500 into a bank account that earned simple interest each year. After 2 years, he had earned $2975 in interest.

No money was deposited into or withdrawn from the account.

What was the annual interest rate?

Enter your answer in the box.

Answers

Answer:  8.5%

Step-by-step explanation:

Formula : Simple interest = (Principal) x (annual interest rate) x (Time)    (i)

Given: Principal : P = $ 17,500

Time : 2 years

Simple interest : I = $ 2975

Let r = annual

[tex]2975=17500\times(r)\times(2)[/tex]

[tex]\Rightarrow\ r=\dfrac{2975}{17500\times2}\\\\\Rightarrow\ r=0.085\\\\\Rightarrow\ r=0.085\times100\\\\\Rightarrow\ r=8.5\%[/tex]

Hence, The annual interest rate was 8.5%.

0.3

Write how u solved it
​

Answers

Answer:

0.3

Step-by-step explanation:

Answer:

3.0

Step-by-step explanation:

Here we have a rectangle split into ten parts with 7/10 shaded in blue. The question asks what decimal represents the portion, alright, let's go down the list.

0.003 is also known as 3 thousandths, meaning that we would need a thousand little squares as our figure. Clearly this isn't the case, so 0.003 is wrong.

0.03 is also known as 3 hundredths, meaning  that we would need a hundred little squares as our figure, this also isn't the case, so 0.03 is wrong.

0.3 is known as 3 tenths, yes this could represent our figure, but it doesn't represent the finished portion, which would be 1.0, this means that only one part will be shaded in the figure we have now, leaving it to be wrong.

This leaves us with 3.0

You are trying to make it so that the one of the (  )= 0.

An example is (x+15) or (2x+3)

the first l one would be x= -15 since -15+15 would equal 0.

The second one is -3/2 since it would be -3+3 which would equal 0.

also since the equation starts with x( or -x it doesn't really matter) one of the zeros would also be 0.

In training for a swim meet, Logan swam 750 meters in \large \frac {1}{3} 3 1 ​ of an hour. His swimming partner, Mila, swam \frac {2}{3} 3 2 ​ of Logan's distance in \frac {1}{4} 4 1 ​ of an hour. what is milas average speed

Answers

Answer:

2 km/hr

Step-by-step explanation:

Distance traveled by Logan = 750 m = 0.75 km = [tex]\frac{3}{4}\ km[/tex]

Time taken by Logan = [tex]\frac{1}{3}\ hours[/tex]

To calculate the speed using time and distance, following formula is used:

[tex]\text{Average Speed =} \dfrac{\text{Total Distance}}{\text{Total Time}}[/tex]

Speed of Logan :

[tex]\dfrac{\frac{3}{4}}{\frac{1}{3}}\\\Rightarrow \dfrac{9}4\ km/hr[/tex]

Distance traveled by Mila = [tex]\frac{2}{3}[/tex] of Logan's distance:

[tex]\frac{2}{3}\times \frac{3}{4} = \frac{1}{2}\ km[/tex]

Time taken by Mila = [tex]\frac{1}{4}\ hr[/tex]

As per formula above:

Average Speed of Mila is given as:

[tex]\dfrac{\frac{1}{2}}{\frac{1}{4}}\\\Rightarrow \dfrac{4}{2}\\\Rightarrow \bold{2 km/hr}[/tex]

Matthew invested $2,000 in a compound interest account for 3 years. The interest rate was 5%. How much money would it be in the end of third year in Mattew's account?

Answers

Answer:

$2,315.25

Step-by-step explanation:

2000 x 0.05 = 100

2000 + 100 = 2100

After year one: 2100

2100 x 0.05 = 105

2100 + 105 = 2205

After year two: 2205

2205 x 0.05 = 110.25

2205 + 110.25 = 2315.25

After year three: 2315.25

Find each amount:



3.8% of 25

Answers

Answer:

0.95

Step-by-step explanation:

3.8 % of 25 is equal to 0.95.

To find 3.8 % of 25, we can calculate it using the following formula : Amount = ( Percentage / 100 ) * Base.

In this case, the percentage is 3.8 and the base is 25.

Using the formula , we have : Amount = ( 3.8 / 100 ) * 25.

First, we divide 3.8 by 100, which gives us 0.038. Then, we multiply 0.038 by 25 to find the amount.

Calculating, we have : Amount = 0.038 * 25 = 0.95.

Therefore, The value of 3.8 % of 25 is equal to 0.95.
