Answer:
Step-by-step explanation:
We can immediately assume that the answer is either the first or third one based off of the second statement. A product is the result of multiplication, and if you see a number and letter together like in the first and third answers, it means they are to be multiplied. For example, 2a = 2 x a. With the first statement, there are 2 terms in all of the equations so that's no help, but the word sum is the result of addition. In which all two terms are added, so . . . also no help. :( Now the last statement. The thing that will conclude all of your questions. A quotient is the result of division, and it's supposed to be between b and 4. As we can see, in the third equation, they subtract b and 4. That's not division! So that leaves us with one answer. The first equation. . .

Solve the quadratic equation by completing the square. 0 = x2 – 6x + 4 –4 = x2 – 6x –4 + 9 = (x2 – 6x + 9) 5 = (x – 3)2
Answers
Answer:
x = 3±√5
Step-by-step explanation:
Given the quadratic equation;
0 = x² – 6x + 4
Swap sides
x² – 6x + 4= 0
Subtract 4 from both sides
x² – 6x + 4 - 4= 0 - 4
x² – 6x = -4
Complete the square;
Add the square of half of coefficient of x to both sides
Coefficient of x = -6
Half of Coefficient of x = -6/2 = -3
square of the half of Coefficient of x = (-3)²
Add (-3)² to both sides
x² – 6x + (-3)² = -4 + (-3)²
(x-3)² = -4 + 9
(x-3)² = 5
Take the square root of both sides
x - 3 = ±√5
x = 3±√5
This gives the solution to the equation

3400 km is decreasing at a rate of 6.5% each year so after 7 years how much is left
Answers
Answer:
1547 km
Step-by-step explanation:
1547 km remain due to consistent decrease in the rate of 3400 km. As stated 6.5% decreases each year, and you are wanting to see the amount left after 7 years. So I said 0.065 x 7 = 0.455 (Because you want to move the decimal two places to the right in this case when plugging in the percentage into an equation.) So, now since I'm left with0.455 for the 7 years I simply multiplied that by 3400 km to get my answer. Which gave me the value 1547 km.
What is the product of 7.1 * 10^3 and 5.8 * 10^2 expressed in scientific notation?
Answers
Answer:
4.118 * 10^6
Step-by-step explanation:
When you multiply exponents, you just add the exponents together, so 10^2 * 10^3 is 10^5. Then you just multiply the 7.1 and the 5.8, which is 41.18. However, scientific notation should have only 1 digit above the decimal spot, so you make the number smaller from 41.18 to 4.118, so you add 1 exponent to the 10^5.
41.18*10^5 = 4,118*10^6
(EDIT, THE GUY WHO COMMENTED IS CORRECT, SCIENTIFIC NOTATION IS WHEN THE DIGIT IS GREATER THAN 1 OR LESS THAN 10, SO IT WOULD BE 4.118*10^6)
Answer:
411.8 · [tex]10^{4}[/tex]
Step-by-step explanation:
7.1 · 10³ × 5.8 · 10²
7.1 × 5.8 = 41.18
10³ + 10² = [tex]10^{5}[/tex]
41.18 · [tex]10^{5}[/tex]
Scientific notation can only have one digit after the decimal.
411.8 · [tex]10^{4}[/tex]

12) There are two rectangular doors that are similar. The smaller door has a height of 3 ft. and a width of 2 ft. The bigger door has a width of 8 ft. What is the height of the bigger door? (Draw a picture, set up a proportion, and show all work.)(3pts)
Answers
Answer:
it's twelve you're welcome
Answer:
12 ft
Step-by-step explanation:
Since the doors are similar then the ratios of corresponding dimensions are equal.
let x be the height of the bigger door, then
[tex]\frac{small}{big}[/tex] : [tex]\frac{3}{x}[/tex] = [tex]\frac{2}{8}[/tex] ( cross- multiply )
2x = 24 ( divide both sides by 2 )
x = 12
Height of the bigger door is 12 ft

A study was conducted to see if students given extra oxygen prior to taking the SAT could improve their scores. It was found that 42 of 66 randomly selected students who received oxygen prior to taking the SAT improved their scores while 35 of 63 randomly selected students who were just given normal air improved their SAT scores. Which procedure should be used to see if there is evidence that students who breathed oxygen significantly improved SAT scores
Answers
Answer:
Hypothesis testing of ' significance of difference between means'
Step-by-step explanation:
Study conducted to tests whether oxygen level prior SAT score improves test score. This can be done through - Hypothesis testing of ' significance of difference between means'.
Where x1 & x2 represent mean values of SAT test score before (or without) & after (or with) oxygen.
Null hypothesis [H0] = x1 = x2 , Alternate Hypothesis [H1] : x1 < x2
