Answer:
Step-by-step explanation:
Use the Quadratic Formula.
-x² - 4x + 16 = 0
x = [4±√(4²-4(-1)(16)]/[2(-1)] = [4±√80]/(-2) = [4±4√5]/(-2) = -2±2√5
The matrix is used to solve a problem. Which of the following would be a solution to the problem?
8y + -5(-y + 2)
Pls help simplify the expression !!
Answer:
13y-10
Step-by-step explanation:
Expand: -5(-y+2): 5y-10
Add similiar elements: 8y+5y=13y
=13y-10
Answer:
-5 x -y = 5y
-5 x 2 = -10
8y + 5y = 13y
therefore your expression is:
13y - 10

Step-by-step explanation:
Allison lives in Kansas City, which has coordinates of 39o5'59" N, 94o34'41 W (39.0997o N, 94.5783o W). (Earth's radius is 3950 miles). What is Allison's angular velocity in radians/hour? What is Allison's linear velocity, with respect to the center of earth in miles per hour?
Answer:
Allison's angular velocity is approximately π/12 radians/hour
Allison's linear velocity, with respect to the Earth, v is approximately 802.52 miles/hour
Step-by-step explanation:
The coordinates of Kansas City where Allison lives = 39°5'5'' N, 94°34'41''W (39.0997° N, 94.5783° W)
The radius of the Earth, R = 3950 miles
The rate of rotation of the Earth ≈ 2·π radians in 24 hours
The angular velocity of the Earth, ω ≈ 2·π/24 radians/hour ≈ π/12 radians/hour
The angular velocity of the Earth = Allison's angular velocity ≈ π/12 radians/hour
Allison's angular velocity, ω ≈ π/12 radians/hour
Allison's radius or revolution with respect to the axis of the Earth, r = 3950 miles × cos(39.0997°) ≈ 3,065.39635 miles
The linear velocity, v ≈ ω × r
∴ v ≈ π/12 radians/hour × 3,065.39635 miles = 802.518887792 miles/hour
Allison's linear velocity, with respect to the Earth (0 linear velocity), v ≈ 802.52 miles/hour
15n+24-4(n-3)+6-2n=105
Answer:
n = 7

2. Write the equation of the line parallel to y = -4x/3 + 5 thru (-6,1). Show all work.
Answer:
[tex]\boxed {\boxed {\sf y= - \frac{4}{3} x -7}}[/tex]
Step-by-step explanation:
We can find the equation using the point-slope formula.
[tex]y-y_1=m(x-x_1)[/tex]
where (x₁, y₁) is the point and m is the slope.
We already know the point is (-6,1). We must find the slope.
We are told the line is parallel to y=-4x/3 +5. Since this line is in y=mx+b form, the slope (m) must be -4/3. Parallel lines have equal slopes, so the line we are finding also has a slope of -4/3
Next, define values for the variables.
[tex]x_1= -6 \\y_1= 1\\m= - \frac{4}{3}[/tex]
Substitute the values into the formula.
[tex]y-1= - \frac{4}{3} (x--6)[/tex]
[tex]y-1= - \frac{4}{3} (x+6)[/tex]
Now put the equation into the form y=mx+b. First, distribute the -4/3 .
[tex]y-1= - \frac{4}{3} *x+ - \frac {4}{3}*6[/tex]
[tex]y-1= - \frac{4}{3} x - 8[/tex]
Add 1 to both sides to isolate y.
[tex]y-1+1= - \frac{4}{3} x - 8+1[/tex]
[tex]y= - \frac{4}{3} x -7[/tex]
The equation of the line is y=-4/3x -7

Please help me find all the missing angles
Answer:
Look at image I attached below.
Step-by-step explanation:
Important points to memorize when finding missing angles like these:
Two angles directly across from each other, not next to, are equal. All angles that are on one side of a straight line add up to 180°, because a straight line has an angle measure of 180°.A full spin-around equals 360°. All angles in any triangle add up to 180°.When you know all these important rules, the rest is just a matter of adding and subtracting.

Find the slope of BG, and HL using the coordinates; B(-4, 3), G(-2, 4), H(1, -2), L(-1, -3). then determine if the lines are parallel.
Answer:
0.5 or [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
BG = [tex]\frac{4-3}{-2--4}[/tex] = 0.5
HL = [tex]\frac{-3--2}{-1-1}[/tex] = 0.5
This mean that the lines are parallel ..
How many times does the line y=-6 intersect with the circle x^2+y^2=36?
Answer:
a) The line intersects with the circle once.
b) Tangent
Step-by-step explanation:
We are given the following equation for the circle:
[tex]x^2 + y^2 = 36[/tex]
How many times does the line y=-6 intersect with the circle?
We have to find the values of x when [tex]y = -6[/tex]
So
[tex]x^2 + y^2 = 36[/tex]
[tex]x^2 + (-6)^2 = 36[/tex]
[tex]x^2 + 36 = 36[/tex]
[tex]x^2 = 0[/tex]
[tex]x = 0[/tex]
Since the line intersects the circle at one point, it is tangent to the circle.
The line intersects with the circle once.
Josie does 9 minutes
of stretches before she runs. She runs for
20 minutes. Then she does 7 minutes of cool
down exercises. The clock shows the end time 3:45 of
her workout. At what time does Josie start her
workout? Describe how you found the time.
Answer: Josie starts working out at 3:09
Step-by-step explanation: I found this answer by adding the workout time together.
Answer:
3:09
Step-by-step explanation:
First add the total time of the workout
20+9+7=36
then subtract the end time 3:45 with the workout time:
3:45-00:36=3:09
Check work:
3:09+00:36=3:45

Calculate the lateral surface area of the rectangular prism:
The sum of three numbers is 83. The first number is 8 more than the second. The third number is 3 times the second. What are the numbers?
Answer:
23, 15 and 45
Step-by-step explanation:
a+b+c = 83
a = b + 8
c = 3*b
(b+8) + b + 3*b = 83
5*b + 8 = 83
5*b = 75
b = 15
a = b + 8 = 15 + 8 = 23
c = 3*b = 3*15 = 45
Verification
a+b+c = 23 + 15 + 45 = 83; correct
