Answer:
A
Step-by-step explanation:
Remember that tangent is the ratio of sine over cosine.
[tex]\tan(\theta)=\frac{\sin(\theta)}{\cos(\theta)}[/tex]
In the unit circle:
Sine refers to the y-coordinate. Cosine refers to the x-coordinate.Our x-coordinate is -√2/2 and our y-coordinate is √2/2.
So, substitute -√2/2 for cosine and √2/2 for sine. This yields:
[tex]\tan(\theta)=\frac{\sqrt2/2}{-\sqrt2/2}[/tex]
Since the numerator and the denominator are the same save for a negative, we can cancel them:
[tex]\tan(\theta)=-1[/tex]
So, our answer is A.

A forklift has a maximum carrying capacity of 1,400 pounds. a. Each box at the warehouse weighs 50 pounds. Write an inequality to show the number of boxes that the forklift can hold. b. A 150-pound crate is used to hold the boxes on the forklift. What is the maximum number of boxes that the forklift can carry in the crate?
Answer:
a. 50x ≤ 1400 boxes
b. 25 boxes
Step-by-step explanation:
A forklift has a maximum carrying capacity of 1,400 pounds.
a. Each box at the warehouse weighs 50 pounds. Write an inequality to show the number of boxes that the forklift can hold.
Let the weight of this box be represented as x
Hence, the inequality to show the number of boxes the forklift can hold us
50 pound × x ≤ 1400 pounds
50x ≤ 1400
b. A 150-pound crate is used to hold the boxes on the forklift. What is the maximum number of boxes that the forklift can carry in the crate?.
We know already the maximum load the forky can carry is 1400
Hence, our equation is:
150 + 50x ≤ 1400
50x ≤ 1400 - 150
50x ≤ 1250
x ≤ 1250/50
x ≤ 25
The maximum number of boxes the forklift can carry in the crate is 25 boxes
Carlos travelled a certain distance from home to the campgrounds on his dirt bike at a speed of 50 km/h and returned at a speed of 60 km/h. How can carlos find the distance between his home and the campgrounds if the total time traveling was 11 hours.
Answer:
110kmStep-by-step explanation:
"Carlos travelled a certain distance from home to the campgrounds on his dirt bike at a speed of 50 km/h and returned at a speed of 60 km/h. How can carlos find the distance between his home and the campgrounds if the total time traveling was 11 hours"
Given data
initial speed u=50km/h
final speed v=60km/h
time taken t=11hours
change in speed= 60-50
=10km/h
we know that the expression for speed is given as
speed= distance/time
let the distance be x
10=x/11
x= 10x11
x=110km
Therefore the distance is 110km
At the end of a card game, James scored −16 points, and Alexis scored −10 points. Enter an inequality in the box to compare the points James and Alexis scored.
Answer:
-16 < -10
-10 > -16
Step-by-step explanation:
James = -16
Alexis = -10
-16 < -10
This means, James scored less than Alexis at the end of the card game
-10 > -16
This means Alexis scored more than James at the end of the card game
The inequality that compares the points Alexis and James scored could either be any of the following:
-16 < -10
-10 > -16
A tree in Sam's backyard was approximately 14 ft tall. The height of the tree is increasing at an average rate of .003 ft per month. Which function can be used to find the height of the tree in x months since it was measured?
Answer:
[tex]f(x)=0.003x+14[/tex]
Step-by-step explanation:
Let the linear function to represent the height of tree be:
[tex]f(x) =mx+c[/tex]
Where [tex]x[/tex] is the time in months
[tex]m[/tex] is the rate of change in the height of tree each month.
[tex]c[/tex] is the initial height of the tree.
Here, we are given that:
The initial height of the tree is 14 ft.
Increase in the height = 0.003 ft per month
Putting the values in the equation of function:
[tex]f(x)=0.003x+14[/tex]
So, the function [tex]f(x)=0.003x+14[/tex] can be used to find the height of tree in [tex]x[/tex] months since it was measured.
f(x)=12x^4-4√x+7/x^2

Marta and Guadalupe are saving for a car. Marta has $500 in her bank account when Guadalupe opens a bank account with zero dollars. Marta deposits $75 into her account each week for x weeks. Guadalupe deposits $95 into her account each week for x weeks. These accounts do not earn interest. Which inequality represents this situation when the amount of money in Guadalupe's account is greater than the amount of money in Marta's account?
Answer:
x>20
Step-by-step explanation:
given that
Marta has $500 in her bank account
Marta deposits $75
the total amount in the account after x weeks is
y=500+75x----------1
Guadalupe deposits $95 into her account each week for x weeks.
the total amount in the account after x weeks is
y=95x-----------2
equating 1 and 2 we have
500+75x=95x
solving for x we have
500=95x-75x
500=25x
x=500/25
x=20
the inequality is
x>20

Prove: ∠JNM ≅ ∠NMI
According to the given information in the image, segment JK is parallel to segment HI while ∠JNM and ∠LNK are vertical angles. ∠JNM and ∠LNK are congruent by the Vertical Angles Theorem. Because ∠LNK and ∠NMI are corresponding angles, they are congruent according to the Corresponding Angles Theorem. Finally, ∠JNM is congruent to ∠NMI by the Transitive Property of Equality.
Alternate Interior Angles Theorem
Corresponding Angles Theorem
Vertical Angles Theorem
Same-Side Interior Angles Theorem
Answer:
Alternate Interior Angles Theorem
Step-by-step explanation:
To put it simply; they are both internal angles. N is the internal line and as both JNM and NMI are angles that use the line N both are interior angles. They are clearly on oppisite sides of the line N, making them "Alternate Interior Angles".
Just took the test. :)
The answer is the Alternate Interior Angles Theorem option first is correct.
What are vertically opposite angles?It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.
The missing figure is attached in the picture please refer to the picture.
We have:
Segment JK is parallel to segment HI while ∠JNM and ∠LNK are vertical angles. ∠JNM and ∠LNK are congruent by the Vertical Angles Theorem
As we know, both angles have internal angles. Since JNM and NMI are angles that both employ the internal line N, they are both interior angles. N is the internal line.
Thus, the answer is the Alternate Interior Angles Theorem option first is correct.

Answer:
Option (B)
Step-by-step explanation:
By exterior angle theorem,
Exterior angle of a triangle is equal to the sum of two opposite interior angles.
By the given theorem,
8x - 30 = (4x + 8) + (2x + 2)
8x - 30 = 6x + 10
8x - 6x = 40
2x = 40
x = 20
m∠BAC = (2x + 2) = (2×20) + 2
= 42°
Therefore, Option (B) will be the answer.
Which value of x makes the equation 3+0.75(x-2)=0.5(x+20)
Answer:
x = 34
Step-by-step explanation:
We need to find the value of x in the given equation :
3+0.75(x-2)=0.5(x+20)
Solving as follows:
3+0.75x-1.5=0.5x+10
Taking like terms together,
3-1.5-10=0.5x-0.75x
-8.5=-0.25x
[tex]x=\dfrac{8.5}{0.25}[/tex]
x = 34
So, the value of x is 34.

Step-by-step explanation:
If we subtract 3 from both sides we get:
x = x
If we subtract x from both sides of that, we get:
0 = 0.
Well... 0 is ALWAYS equal to 0, so there is no answer that can make that statement invalid, meaning that all numbers are solutions.
-6x + 5(-2x - 11) = 137
What is x equal to?
Answer:
x=−12
Step-by-step explanation:
−6x+5(−2x−11)=137
Step 1: Simplify both sides of the equation.
−6x+5(−2x−11)=137
−6x+(5)(−2x)+(5)(−11)=137(Distribute)
−6x+−10x+−55=137
(−6x+−10x)+(−55)=137(Combine Like Terms)
−16x+−55=137
−16x−55=137
Step 2: Add 55 to both sides.
−16x−55+55=137+55
−16x=192
Step 3: Divide both sides by -16.
−16x/−16=192/−16
Answer:
-6x-10x-55=137
-16x-55=137
-16x=137+55
-16x=192
X=192/16
X=12

5x - 32x - 9
Answer:
x = -2 :)
Step-by-step explanation:
5x - 3 = 2x - 9
3x = -6
-6/3 = -2
Answer:
x = -2
Step-by-step explanation:
I dunno which one to answer so I'll do both. (the question you posted or the picture??)
5x - 32x - 9
First we can combine the like terms 5x and -32x. Which is -27x
We can't combine -9 with anything so it stays the same.
-27x - 9
________________________________
5x - 3 = 2x - 9
-2x -2x
3x - 3 = -9
Here I subtracted -2 from both sides.
3x - 3 = -9
+3 +3
3x = -6
Divide both sides by 3 to isolate the variable.
x = -2
