- 3.5 ____ 2.8
7.4 ____ - 9
Answers
Answer:
-3.5 < 2.8
7.4 > -9
Step-by-step explanation:
If you have a negative number and a positive number the positive number is always greater.
When you have a negative number and another negative, the smallest number is greater.
For example: -2.5 -3.7
-2.5 is greater than -3.7 because it is less negative.
-2.5 > -3.7
When you have a positive number and a positive number, the biggest number is greater.
For example: 8.3 4.2
8.3 is greater than 4.2 because it is a bigger number.
8.3 > 4.2
Write a system of equations that represents the situation.
The sum of two numbers is 15. The second number is equal to the first number plus 1.
Let x = the first number Let y = the second number
First sentence: Equation 1:
Second sentence: Equation 2:
Do not include spaces in your equations.
Part 2: Find the numbers. ( ,)
Answers
Answer:
See below.
Step-by-step explanation:
Let x = the first number
Let y = the second number
First sentence: Equation 1: x+y=15
Second sentence: Equation 2: y=x+1
Part 2: Find the numbers.
x + y = 15
y = x + 1
x + x + 1 = 15
2x + 1 = 15
2x = 14
x = 7
y = x + 1 = 7 + 1 = 8
The numbers are 7 and 8.
Answer:
x = 7
y = 8
Step-by-step explanation:
x + y = 15
y = x + 1
Part 2:
x + (x + 1) = 15
x + x + 1 - 1 = 15 - 1
2x = 14
2x/2 = 14/2
x = 7
y = 7 + 1
y = 8
Therefore, x = 7 and y = 8
While on an 8.0 h trip, a car traveled for 3.5 h at an average speed of 90 km/h before stopping for 1.0 h. The car then traveled for 2.0 h at an average speed of 80.0 km/h For the last 1.5 h, the car traveled at an average speed of only 70.0 km/h. What was the average speed of the car for the entire 8.0 h trip?
Answers
Answer:
72.5 km/h
Step-by-step explanation:
Multiply the km/h by how many hours your going at that speed/total number of hours on trip.
(90x(3.5/8))+(80x(2/8))+(70x(1.5/8))
39.375+20.5+13.125
72.5km/h

Which logarithmic equation is equivalent to this exponential equation?
12=5^x
Answers
Given:
The equation is:
[tex]12=5^x[/tex]
To find:
The logarithmic equation that is equivalent to the given exponential equation.
Solution:
According to the property of logarithm:
[tex]a=b^x\Leftrightarrow \log_b a=x[/tex]
We have,
[tex]12=5^x[/tex]
Here, [tex]a=12,b=5[/tex]. By using the above property of logarithm, we get
[tex]\log_{5}12=x[/tex]
[tex]x=\log_{5}12[/tex]

Please could you could give me a step by step.
Answers
Answer:
Step-by-step explanation:
We can use Hypotenuse Theorem for this:
For triangle ABC,
AC²=CB²+BA²
9²=CB²+3²
Switch the sides
-CB²=3² -9²
-CB²= 9-81
-CB²= -72
the signs cut each other
CB²=72
the square changes sides
CB=√72
CB= 8.49 cm
Now triangle CBD
We have the length of CB but not the other two whereas we have the angle
It will be sin
As we know sin= O/H
Here O is CB whereas H is CD
Put the values
sin 50= 8.49/H
H= 8.49 ÷sin 50
Calculate
H=11.1 cm
As we know H is CD so CD is 11.1 cm

What is the corresponding point on the unit circle for the given radian measure?
0 = 7pi/6
Answers
Answer:
Answer is B: (-sqrt(3/2 , -1/2)
Step-by-step explanation:
First convert radians to degrees
theta = (7pi/6)*(180/pi)
=210 degrees
Cos(210 degrees)= -sqrt3/2
Thats the x coordinate
sin(210 degrees)= -1/2
thats the y coordinate
Answer:
The corresponding point on the unit circle for the radian measure is [tex](\frac{\sqrt{3} }{2},\frac{1}{2})[/tex]
Step-by-step explanation:
What is unit circle?
A unit circle is typically drawn around the origin (0,0) of a X,Y axes with a radius of 1.
What is radian measure?
One radian is the measure of a central angle that intercepts an arc s equal in length to the radius r of the circle.
The radian measure is,
α=[tex]\frac{7\pi }{8}[/tex]
Changing to degree measure,
[tex]\frac{7\pi }{6} *\frac{180}{\pi } \\=210^{o}[/tex]
The measure on the unit circle is,
(cos [tex]\alpha[/tex] , sin [tex]\alpha[/tex])=(cos 210 , sin 210)
=[tex](\frac{\sqrt{3} }{2},\frac{1}{2})[/tex]
