Answer:
Acute Angles: ∠TLS, ∠SLT, ∠ULR Right Angles: --------- Obtuse Angles: ∠RLT, ∠SLU, ∠ULS, Straight Angles: ∠RLS, ∠TLU Not angles: ∠TRLStep-by-step explanation:
The lines intersect at point L, so all angles have a vertex (middle letter) L so there is no angle TRL
Straight angle is a line with dot-vertex, so the straight angles are ∠RLS and ∠TLU.
∠TLS is less than 90° then it is acute angle (∠SLT is the same angle). ∠ULR is vertex angle to ∠TLS, so it's also acute angle.
Two angles adding to straight angle mean that they are both right angles or one is acute and the second is obtuse. ∠TLS is acute so ∠RLT is obtuse (they adding to ∠RLS) and ∠SLU is obtuse (they adding to ∠TLU). ∠ULS is the same angle as ∠SLU.

Step-by-step explanation:
AC = AB + BC
25x - 19 = 9x + 7 + 5x + 7
25x - 19 = 14x + 14
25x - 14x = 14 + 19
11x = 33
x = 33/11
x = 3
AB = 9x + 7
= 9(3) + 7
= 27 + 7
= 34

Which expression has the same value as tan(-45°)?
-tan(45°)
-cot(135°)
-sin(270°)
-cos(180°)
Answer:
I think it's cot(135°)
Step-by-step explanation:
Cot 135° = Cot (π/2 + 45)
and,
Cot (π/2+45)= -tan (45),
because when a trigonometric ratio is impressed by using π/2 the ratio should be changed its opposite like sin value turns into a cos value, tan value turns into cot and vise versa. Then as 135° is in the second sector that means π/2<135°<π. So it should be -tan(45°)
As tan-45°= -tan 45° i think the answer is second one aka cot(135°)
The equivalent expression of tan(-45) is cot(135)
The given trigonometric expression is: tan(-45).
To do this, we make use of the following trigonometry ratio
[tex]\cot (\frac{\pi}{2}+\theta)= -\tan (\theta)[/tex]
Substitute 45 for [tex]\theta[/tex].
So, we have:
[tex]\cot (\frac{\pi}{2}+45)= -\tan (45)[/tex]
In trigonometry, [tex]\frac{\pi}{2} = 90[/tex].
So, we have:
[tex]\cot (90+45)= -\tan (45)[/tex]
Add 90 and 45
[tex]\cot (135)= -\tan (45)[/tex]
Also, we have:
[tex]\tan (-45)= -\tan (45)[/tex]
So, the equation becomes
[tex]\cot (135)= \tan (-45)[/tex]
Rewrite as:
[tex]\tan (-45) = \cot (135)[/tex]
Hence, the equivalent expression of tan(-45) is cot(135)

-14-7(9v+3)=13v+41
Answer:
v=−1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−14−7(9v+3)=13v+41
−14+(−7)(9v)+(−7)(3)=13v+41(Distribute)
−14+−63v+−21=13v+41
(−63v)+(−14+−21)=13v+41(Combine Like Terms)
−63v+−35=13v+41
−63v−35=13v+41
Step 2: Subtract 13v from both sides.
−63v−35−13v=13v+41−13v
−76v−35=41
Step 3: Add 35 to both sides.
−76v−35+35=41+35
−76v=76
Step 4: Divide both sides by -76.

A triangle with one obtuse angle must also have two acute angles
Answer:
True! All triangle angles must add up to 180 degrees, thus an angle greater than 90 degrees would only give the rest of the angles 90 degrees to work with, which would make them acute.

(2,-1) and (4,0) in slope-intercept form
Answer:
y = [tex]\frac{1}{2}[/tex] x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (4, 0)
m = [tex]\frac{0+1}{4-2}[/tex] = [tex]\frac{1}{2}[/tex] , thus
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (4, 0 ), then
0 = 2 + c ⇒ c = 0 - 2 = - 2
y = [tex]\frac{1}{2}[/tex] x - 2 ← equation of line

How many ink cartridges can you buy with 150 dollars if one cartridge costs 15 dollars ?
Answer:
10
Step-by-step explanation:
Very easy equation if you know how to do it. All you need to do is divide your total amount of something (in this case "150" as that's our amount of "money we're given") by whatever the price or amount is. (In this case 15. Each cartridge costs $15. I'm not amazing at explaining things like this.. Sorry about that. If you have any questions about this feel free to let me know!)
So to put it "all together":
150 ÷ 15 = 10.
10 is your answer.

Answer:A
Step-by-step explanation: the other dude is wrong
and if im right mark me brainiest
The best modeled by a discrete graph is body temperature of an athlete during a workout.
The correct option is (D)
What is Discrete graph?A discrete graph is one with scattered points. They may or may not show a direction or trend. They don't have data in between the points already given.
A continuous graph has a line because there is data in between the points already given.
So, according to the condition the best modeled discrete graph is body temperature of an athlete during a workout.
This is because for the body temperature measure, we only need to measure it once in a while.

2. Mourette is a member of her high school golf team. She hits a golf ball
off the ground with an initial upward velocity of 60 meters per second.
a. Write a formula describing the height h of the ball (in meters)
after t seconds.
b. After how many seconds, to the nearest tenth, will the
golf ball land on the ground?
c. What is the maximum height the golf ball reaches?
please help!
Answer:
a. h = 60t − 4.9t²
b. 12.2 seconds
c. 183.7 meters
Step-by-step explanation:
a. Given:
y₀ = 0 m
v₀ = 60 m/s
a = -9.8 m/s²
y = y₀ + v₀ t + ½ at²
h = 0 m + (60 m/s) t + ½ (-9.8 m/s²) t²
h = 60t − 4.9t²
b. When the ball lands, h = 0.
0 = 60t − 4.9t²
0 = t (60 − 4.9t)
t = 0 or 12.2
The ball lands after 12.2 seconds.
c. The maximum height is at the vertex of the parabola.
t = -b / (2a)
t = -60 / (2 × -4.9)
t = 6.1 seconds
Alternatively, the maximum height is reached at half the time it takes to land.
t = 12.2 / 2
t = 6.1 seconds
After 6.1 seconds, the height reached is:
h = 60 (6.1) − 4.9 (6.1)²
h = 183.7 meters
