Which statement about 214° is correct?
O A. tan 214° < 0
O B. sin 214° < 0
O C. cos 214° > 0
Answer:
B.
Step-by-step explanation:
214 degree terminates in the 3rd quadrant.
Sine and cosines are both negative there.
This means that sin(214)<0 and cos(214)<0.
If sine and cosine are both negative and since tangent is the quotient of them, then tangent is positive, or tan(214)>0.

Q8 A taxi company charges £5 standing charge and £1.50 per mile for a journey.
A man travels in a taxi for 12.2 miles.
What is the cost of his journey?
Show your working
Answer:
£23.30
Step-by-step explanation:
First, find the cost from traveling 12.2 miles. Since the cost is £1.50 per mile, multiply 12.2 by 1.5:
12.2(1.5)
= 18.3
Add the standing charge to this:
18.3 + 5
= 23.3
So, the cost of his journey is £23.30
2+2=?
i dont remember this, its too complex for me someone help asap
ahem ahem
2+2=69
it's 4 thanks for the points
I don't see how to do this...............................
Step-by-step explanation:
So visually youre given the function
for h(-4) it can also be written as h(-4) = y
what do you get for y when you substitute - 4 for x?
All you have to do is trace the line until you get to x=-4 and then find the y that corresponds to it (looks like around y= - 1)
for the other one h(x) = - 5
what do you get for x when you substitute - 5 for y?
what you do is similar, trace the line along the y-axis and see what x-value you get for y =-5
Answer:
3 and x = 0
Step-by-step explanation:
To find the value of h(- 4)
Locate x = - 4 on the x- axis, go vertically up to meet the graph at (- 4, 3 )
Then the value of h(- 4) = 3
For h(x) = - 5
Locate y = - 5 on the y- axis. This is the point (0, - 5)
then the value of x for which h(x) = - 5 is x = 0
Two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 15 hours. Together they charged a total of $2475 . What was the rate charged per hour by each mechanic if the sum of the two rates was $200 per hour?
Answer:
1st: 105/h
2nd: 95/h
Step-by-step explanation:
10A+15B=2475 (1)
A+B=200 |*10 => 10A+10B=2000 (2)
From (1) - (2), we have 5B=475, so B=95
then A+95=200 so A is 105
Use the change of base formula and a calculator to approximate each logarithm. Round to
three decimal places.
log14 (16)
Answer:
[tex]1.051[/tex]
Step-by-step explanation:
The change of base formula is given by [tex]\log_a b=\frac{\log b}{\log a}[/tex]
Substituting given values, we have:
[tex]\log_{14} 16=\frac{\log 16}{\log 14}\approx \boxed{1.051}[/tex]

Plzzzzz helppppppp teachersssss
Answer:
1. tan(x) = 9/20
arctan(9/20) ≈ 24.23°
2. cos(x) = 17/32
arccos(17/32) ≈ 57.91°
3. tan(x) = 13/18
arctan ≈ 35.84°
4. sin(x) = 21/28
arcsin(21/28) ≈ 48.59°
Answer:
1 x = 24.2°
2 x = 57.9°
Step-by-step explanation:
You must memorize the definitions of the trig functions and then these problems are easy
1: tan = opposite side/adjacent side
opp side to x is 9 and adjacent side is 20
So, tan x = 9/20
x = arctan (9/20) = 24.2°
2: cos = adjacent side/hypotenuse
adjacent side = 17 and hypotenuse = 32
cos x = 17/32
x = arccos (17/32)
x = 57.9°
You do 3 and 4. Hint: Use the tan function in 3 and the sine function in 4

The angle measurements in the diagram are represented by the following expressions
ZA = 8r+6
B = 4.1 +38
Solve for x and then find the measure of B:
_B =
answer:
∠B = 70°
step-by-step explanation:
as you can see, the angle are alternate exterior anglestherefore, they are EQUALwe can set them equal to each and solve for x first∠A = ∠B
8x + 6 = 4x + 38
4x + 6 = 38
4x = 32
x = 8
now, we will plug in x in the expression for B to find B4(8) + 38
32 + 38
= 70
therefore, ∠B = 70° and x = 8i need help with 4ourth grade math lesson 8 homework helper asap math

"HOT PIZZA" is offering 20% discount on all its pizza
Ali bought a pizza for £5.60 what was the original price
Answer:
Original price was £7.00
Step-by-step explanation:
20% discount means that ali is paying 80% of the full price
.8p = 5.60
Divide both siides by .8
p = 7
Original price was £7.00
Use the graph to answer the following questions. image Activity 1 of 2 Part A: Is the relationship between the distance traveled and the time shown in the graph proportional? A. The relationship is proportional because the ratio of the variables is constant. B. The relationship is not proportional because the graph passes through the origin (0, 0). C. The relationship is proportional because the graph goes up by 5 every time. D. The relationship is not proportional because time increases by 2 and distance traveled increases by 5.
Need help on this one plz
Answer:
3 15/18
Step-by-step explanation:
well, 4 5/18 can't take away 8/18 with the fraction itself. so, you take 5 from 8 and get -3. then, take one whole number away and subtract the 18 from 3 (this was the negative 3) and you have the answer. so to conclude it 5 cant take away 8 so its like carrying. you take one whole number that is 18/18 and you subtract the 18 from 3.

sum of two numbers be 95. if one exceeds the other by 15, find the number
Sum of two number = 95
Let the first number be x, then another number be x + 15.
According to the question, x + x + 15 = 95
=>2x+15=95
=>2x+15-15=95-15
=>2x=80
=>x=40
Hence, the first number = 40
And another number = 40 + 15 = 55.
