Answer:
a = 2
b = 1
c = 1
Step-by-step explanation:
The quadratic equation, 2x² + x + 1 = 0, is expressed in the standard form as ax² + bx + c, where a ≠ 0.
Thus,
a = 2
b = 1 (1 * x = x)
c = 1

Fernando can run 600 meters
in 5 minutes. At this rate,
how many minutes would it
take him to run 1,500
meters?
Answers
Answer:
12.5 minutes
Step-by-step explanation:
Given that,
Fernando can run 600 meters in 5 minutes.
We need to find how many minutes would it take him to run 1500 meters.
ATQ,
600 m = 5 min
1 m = (5/600) min
For 1500 m,
[tex]t=\dfrac{5}{600}\times 1500\\\\t=12.5\ min[/tex]
So, it will take 12.5 minutes to run 1500 m.

Answer:

Step-by-step explanation:
You can divide the shape into pieces several ways. The total area will be the sum of the areas of the pieces.
If we draw a horizontal line across the figure 2 inches up from the bottom, the figure is divided into a triangle and two rectangles.
The triangle has a base of 8 -3-2 = 3 inches, and a height of 4 -2 = 2 inches. Its area is ...
A = (1/2)(3 in)(2 in) = 3 in²
The rectangle below the line has a base of 8 inches and a height of 2 inches. Its area is ...
A = bh = (8 in)(2 in) = 16 in²
The rectangle above the line has a base of 3 inches and a height of 4 inches. Its area is ...
A = bh = (3 in)(4 in) = 12 in²
Then the total area of the figure is ...
(3 + 16 + 12) in² = 31 in² . . . . the area of the figure

O A. log (12) - log (5)
O B. 12. log (5)
O C. log (12) + log (5)
O D. log (12) log (5)
Answers
The expressions that is equivalent to log (12/5) would be A. log (12) - log (5).
What is logarithm and some of its useful properties?When you raise a number with an exponent, there comes a result.
Lets say you get
a^b = c
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
b = \log_a(c)
'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'
We have given an expression as ;
log (12/5)
We know that
[tex]log_a(b) - \log_a(c) = \log_a(\frac{b}{c})[/tex]
So,
log (12/5) = log (12) - log (5)
Thus, the correct option is A. log (12) - log (5)
The expressions that is equivalent to log (12/5) would be A. log (12) - log (5).

Maria decides to increase her homework time of 8 hours per week by 15% Calculate her new homework time. Give your answer in hours and minutes
Answers
Answer:
Maria's homework time is now 9 hours 12 minutes.
Step-by-step explanation:
Since Maria decides to increase her homework time by 15%.
Then,
15% of 8 hours = [tex]\frac{15}{100}[/tex] x 8 hours
= 0.15 x 8 hours
= 1.2 hours
(Note that: 1.2 hours = 1 hour 12 minutes)
15% of 8 hours = 1 hour 12 minutes
her new homework time = 8 hours + 1 hour 12 minutes
= 9 hours 12 minutes

A table of values of a linear function is shown below. Find the output when the input is n . Type your answer in the space provided.
input: 1 2 3 4 n
output: -10 -13 -16 -19 (Blank)
Answers
Answer:
5; -22
Step-by-step explanation:
A linear function has a positive relationship and as such an increase in one variable (input variable) causes an increase in the other variable (output variable) i.e the variables are directly proportional.
Given the following data;
Input: 1 2 3 4 n
Output: -10 -13 -16 -19
For an input variable of 1, 2, 3, 4; the output variable is -10, -13, -16, -19 respectively.
To find the value of n;
We can deduce that the input is increasing by a value of 1.
Thus, n = 4 + 1 = 5
For the output;
We can deduce that the output is increasing by a value of -3.
Thus, the next output = -19 + (-3) = -22
