Answer: 11
Step-by-step explanation:
Answer:
11 square centimeters
Step-by-step explanation:
The area of a rectangle is length times width. A square is a type of rectangle that has four equal sides, so if we know one side we know all four.
A = l x w
121 = l x w
Since we know l and w are equal we can take the square root of 121, which is 11.
Find the reference angle for -7pi/5
Answer:
When the terminal side is in the first quadrant (angles from 0° to 90°), our reference angle is the same as our given angle. This makes sense, since all the angles in the first quadrant are less than 90°. So, if our given angle is 33°, then its reference angle is also 33°.
When the terminal side is in the second quadrant (angles from 90° to 180°), our reference angle is 180° minus our given angle. So, if our given angle is 110°, then its reference angle is 180° – 110° = 70°.
When the terminal side is in the third quadrant (angles from 180° to 270°), our reference angle is our given angle minus 180°. So, if our given angle is 214°, then its reference angle is 214° – 180° = 34°.
When the terminal side is in the fourth quadrant (angles from 270° to 360°), our reference angle is 360° minus our given angle. So, if our given angle is 332°, then its reference angle is 360° – 332° = 28°.

feet to tie down another load on a second trailer. About how much rope does Larry have left? Choose the best estimate.
Responses
A 29 feet29 feet
B 31 feet31 feet
C 28 feet28 feet
D 30 feet30
The feet of rope that Larry has left will be 29 feet.
How to calculate the value?Total number of feet of the rope = 63 feet
Feet that were used = 15.56 + 18.13 = 16 + 18 = 34 feet
Therefore, the feet of rope that Larry has left will be:
= 63 - 34
= 29
Therefore, the feet of rope that Larry has left will be 29 feet.

Answer: an=2(n-1)+1
Step-by-step explanation:
1,3,5,7, …
As the terms progress in the sequence, each term get increased by 2 to get to the next term. Hence, the change is linear and can be modeled with the function y=2(x-1)+1 where y=term value, x=term number and 1 is the first term in the sequence.
y=2(x-1)+1
an=2(n-1)+1 ==> n=term number while an=term value. an=nth term

The cost of a taxi ride, in dollars, is $2 for the first quarter mile plus $0.40 for each quarter mile after that. Jameel cannot
afford to spend more than $20 on a taxi ride.
The equation 2 + 0.4(4m - 1) = 20 can be used to find m, the distance, in miles, that Jameel can travel for $20. What
is the maximum distance?
A) 13.5 miles
B 16.0 miles
C11.5 miles
(D) 14.0 miles
The maximum distance Jameel can travel is 11.5 miles
How to determine the maximum distance?The equation that determines the distance is given as
2 + 0.4(4m - 1) = 20
Subtract 2 from both sides of the equation
So, we have
0.4(4m - 1) = 20 -2
Evaluate the like terms
So, we have
0.4(4m - 1) = 18
Divide both sides by 0.4
So, we have
(4m - 1) = 18/0.4
Evaluate the quotients
So, we have
(4m - 1) = 45
Remove the bracket
So, we have
4m - 1 = 45
Add 1 to both sides of the equation
4m = 46
Divide both sides of the equation by 4
So, we have
x = 11.5
Hence, the maximum distance Jameel can travel is 11.5miles

Find the z-intercepts and the coordinates of the vertex for the parabola y=x2+6x+5 if there is more than one x intercept awpweate them with commas
The x-intercepts of the parabola are (-1,0) and (-5,0) and the coordinates of the vertex are ( -3 , - 4 ).
A parabola is a graphical representation of a function of the form y=g(x) where g(x) is a quadratic polynomial of x.
The locus of a point which is equidistant point also known as focus and equidistant from a given line known as directrix forms a parabola.The general equation of a parabola is given by y =4a(x-h)²+k(h, k) is the vertex of the parabola.The given equation of the parabola is y = x² + 6x + 5
to find the x-intercepts we have to take the value of y at zero.
∴ x² + 6x + 5 = 0
or, x² + 5x + x + 5 = 0
or, x (x + 5) + 1 ( x + 5 ) = 0
or, (x+5)(x+1)=0
either x=-5 or x=-1
Therefore the x-intercepts of the graph is (-1,0) and (-5,0)
Now to find the vertex of the parabola:
y = x² + 6x + 5
or, y = x² + 2·x·3 + 3² - 4
or, y = (x + 3)² - 4
Therefore from the above equation we can say that the vertex of the parabola is at ( -3 , - 4 ).

Differential Equations Dilemma
Show directly that the given functions are linearly dependent on the real line. That is, find a nontrivial linear combination of the
following functions that vanishes identically.
f(x) = 4x, g(x) = 2x², h(x) = 8x-12x²
Enter the non-trivial linearcombination.
(16)4x + (__)2x²+ (__)(8x-12x²) = 0
The equation with nontrivial linear combination is (16)4x + ( -48 )2x²+ (-8 )(8x-12x²) = 0
We can solve this problem following some steps.
Let's assume the value is A for blank one and it is B for blank two.
Now we can rewrite the equation as,
(16)4x + (A) 2x²+ (B)(8x-12x²) = 0
Or, 64x + 2Ax² + 8Bx - 12Bx² = 0
After rearrangement, we can write this equation as,
x ( 64 + 8B) + x²( 2A - 12B) = 0
We can consider the whole equation as zero, only when the coefficient of both x and x² is zero, To complete a nontrivial combination, we have to write,
∴ ( 64 + 8B) = 0 [ Coefficient of x ]
Or , 8B = -64
Or, B = -64/8 = -8
Again following the previous concept we can also write, ( 2A - 12B ) = 0
[ Coefficient of x² ]
Now, we should put the value of B = -8
∵ ( 2A - 12B ) = 0
Or, 2A + 96 = 0
Or, 2A = - 96
Or, A = - 48
So, the value of A is -48, and the value of B is -8
Now we can conclude,
(16)4x + ( -48 )2x²+ ( -8 )(8x-12x²) = 0

The function of f(x) = (x+4)³ + 3 is one-to-one then the value of
[tex]f^{-1} (x) = \sqrt[3]{x} - 4[/tex] and,
[tex]f^{-1} (2) = -2.7401[/tex]
The function f(x) = (x+4)³ + 3
Let us assume,
y = (x+4)³ + 3
What is Invertible function?A function is said to be invertible when it has an inverse. It is represented by [tex]f^{-1}[/tex]. Condition for a function to have a well-defined inverse is that it be one-to-one and Onto or simply bijective.
Then,
y = (x+4)³ and y = 3
Therefore the inverse of y = 3 is the line x = 3
We can solve,
y = (x+4)³
The solution of Inverse function,
So,
[tex]\sqrt[3]{y} = x+4[/tex]
We can get,
[tex]x = \sqrt[3]{y} -4[/tex]
So the inverse of y is [tex]\sqrt[3]{x} -4[/tex]
f(x) = (x+4)³
So the inverse of f(x) is [tex]\sqrt[3]{x} -4[/tex]
Therefore, [tex]f^{-1}( x)[/tex] = [tex]\sqrt[3]{x} -4[/tex]
Then f(x) = 2
[tex]f^{-1} (x) = \sqrt[3]{x} - 4[/tex]
We can substitute f(x) = 2
[tex]f^{-1} (2) = \sqrt[3]{2} -4[/tex]
Since, ∛2 = 1.2599
We can substitute this value,
[tex]f^{-1} (2) = 1.2599-4[/tex]
[tex]f^{-1} (2) = -2.7401[/tex]
Therefore,

The smallest angle on the line will be 36°
What do you understand by straight line segment?A line segment seems to be a straight line that connects two places. A line segment does indeed have a predetermined length. A ruler can be used to determine the shortest distance between the two points.
What is another name for a straight angle?A straight angle in geometry is an angle with a vertex point of 180 degrees. It basically generates a straight line with sides that point in opposite directions first from the vertex. It is also known as "flat angles."
According to the given data:We know the the sum of the straight angle is = 180°
So,
(5a + 18) + (48 - a) + (8a -30 ) = 180°
5a - a + 8a + 18 +48 - 30 = 180°
12a + 36 = 180°
12a = 180 - 36
a = 12°
So putting the value of a in the equation:
(5a + 18) = 5 *12 + 18 = 78°
(48 - a) = 48 - 12 = 36°
(8a -30 ) = 96 - 30 = 66°
36° < 66° <78°

3x+3y +32=3
2x + 4y + 32 = 8
Answer:
It will be (x=1.y=6.z=-6
Answer:
Choice b
(x = 1, y = 6, z = -6)
Step-by-step explanation:
The system of equations is
3x + 4y + 3z = 9 (1)
3x + 3y + 3z = 3 (2)
2x + 4y + 3z = 8 (3)
Subtract (2) from (1) to eliminate the 3x and 3y terms and solve for y
(1) - (2)
==> 3x + 4y + 3z - (3x + 3y +3z) = 9 - 3
==> 3x + 4y + 3z - 3x - 3y - 3z = 6
(3x-3x) + (4y-3y) + (3z-3z) = 6
4y - 3y = 6
y = 6
Subtract (3) from (1) to isolate the x term
(3x - 2x) + (4y-4y) + (3z-3z) = 9 -8
x = 1
Divide equation (2) on both sides by 32 to eliminate the coefficients
Equation (2) ÷ 3
==> (3x + 3y + 3z) / 2 = 3/3
==> x + y + z = 1 (4)
Substitute the values of x and y in Equation (4)
1 + 6 + z = 1
7 + z = 1
Subtract 7 from both sides
==> z = 1-7 = 6
Answer:
(x = 1, y = 6, z = -6)
If Jessie can answer multiplication problems at a rate of 6 problems every 20 seconds. If she has a 10 minute test with 175 questions on it, will she finish in time?
Answer:
yes
Step-by-step explanation:
to solve this you must first find her rate
6 / 20 is her rate
you want to know how many she can do in ten minutes so we must find how many seconds are in 10 minutes
10 * 60 = 600
175 / 600 is the rate needed fro the test
now make them have the same denominator
6 / 20 is also 180 / 600
175/600 is less than 180/600 so yes she will finish the test in time
