Which angle between –180° and 0 has the same cosine value as 275°
Answer:
cos (-85°)
Step-by-step explanation:
[tex] \cos(275 \degree) [/tex]
since cosine is in fourth quadrant:
[tex] \cos(275 \degree) = \cos( \{360 \degree - 275 \degree \}) \\ = \cos( - 85 \degree) [/tex]
-85° is the angle between –180° and 0° that has the same cosine value as 275°.
What is cosine?Cosine is the trigonometric function that is equal to the ratio of the side adjacent to the acute angle in a right angled triangle.
Mathematically,
Cos = Base/Hypotenuse
Now, to calculate cos(275) we have to first determine the quadrant of the given angle.
Since our angle is greater than 270 and less than or equal to 360, it is located in the Quadrant IV.
In the Quadrant IV, the values of cos are always positive.
275 is an obtuse angle so we can write,
Cos(275) = Cos{360+(-85)}
∵ Cos(360+θ) = Cosθ
∴ Cos{360+(-85)} = Cos(-85)
⇒ Cos(275) = Cos(-85)
The required answer is cos(275) = cos(-85)
Hence, -85° is the angle between –180° and 0° that has the same cosine value as 275°.

If ƒ (x ) = 3x2 - x, find ƒ (-2).
I literally have no idea what I'm looking at....maybe I should've paid better attention leading up to the test.
f(x)=3x^2-x
[tex]\\ \rm\longmapsto f(-2)[/tex]
[tex]\\ \rm\longmapsto 3(-2)^2-(-2)[/tex]
[tex]\\ \rm\longmapsto 3(4)-(-2)[/tex]
[tex]\\ \rm\longmapsto 12-(-2)[/tex]
[tex]\\ \rm\longmapsto 12+2[/tex]
[tex]\\ \rm\longmapsto 14[/tex]
Answer:
14
Step-by-step explanation:
f(x) = 3x² - x
To find f(-2), substitute -2 for x into the function f.
f(-2) = 3(-2)² - (-2)Now, use PEMDAS to evaluate the function.
Start by evaluating the exponent.
f(-2) = 3(4) - (-2)Next, multiply 3 and 4 and -2 by -1.
f(-2) = 12 + 2Add the two terms together.
f(-2) = 14The correct answer is f(-2) = 14.
The width of a rectangle
is 11 feet longer than the
length. The perimeter of the The rectangle is 70 feet. Find the length and the width.
Answer:
Hello! The answer to this problem is Length= 27 and Width= 8
Step-by-step explanation:
2(11+2x) +2x = 70
6x + 22 = 70
6x = 48
x = 8
Answer:
Length = 23 feet and width = 12 feet.
Step-by-step explanation:
The width (W) = x and the length (L) is x+11 feet (length must be longer than width).
Perimeter = 2W + 2L = 70
2x + 2(x + 11) = 70
2x + 2x + 22 = 70
4x + 22 = 70
4x =- 70 - 22 = 48
x = 12 = width
So length = 12 + 11 = 23.

if the distance between town a and b is 1350 KM and the distance between town A and C is in the same direction is approximately two fifth of this. what is the approximate distance of town B and C
Answer:
BC = 810 KM
Step-by-step explanation:
It is 2/5 from A to C so the remaining distance 1 -2/5 = 5/5 -2/5 = 3/5 is the distance from C to B
BC = 3/5 * 1350
BC = 810 KM
Please I need help ASAP, I don’t understand anything and it’s due tomorrow
Answer:
Alright, here we go.
11. Those are vertical angles. All vertical angles are equal.
6x + 7 = 8x - 17
2x = 24
x = 12
12. Those are linear angles (adjacent angles on a line). Linear angles = 180.
(11x - 15) + (5x - 13) = 180
16x - 28 = 180
16x = 208
x = 13
13. If BD is perpendicular to AC, that means ∠ABD and ∠CBD = 90°. ∠CBD is made up of angle DBE, which equals (2x - 1)° and angle CBE, which equals (5x - 42)°.
(5x - 42) + (2x - 1) = 90
7x - 43 = 90
7x = 133
x = 19
14. Angles PQS and SQR are equal and halves of angle PQR because of bisector QS. If PQR = 82°, angle PQS = 41°
10x + 1 = 41
10x = 40
x = 4
15. If the bottom angle is (x + 10)°, then the top angle is also (x + 10)° because they're vertical angles. Angle (x + 10) and angle (10x - 61) are linear angles, so they equal 180.
(x + 10) + (10x - 61) = 180
11x - 51 = 180
11x = 231
x = 21
As for y, insert 21 as x for (10x - 61).
10(21) - 61
210 - 61
149
(18y + 5) should also equal 149° bc of vertical angles.
18y + 5 = 149
18y = 144
y = 8
x = 21
y = 8
(16 is crossed off so I'm going to assume you're not doing that one.)
17. If angle MNQ = (8x + 12)°, and it's bisected by NP, we can say that angles MNP and PNQ are equal halves of (4x + 6)°. Now, we were told that angle PNQ = 78°.
4x + 6 = 78
4x = 72
x = 18
This means that angle MNQ = 78 x 2, which is 156.
Now to find y, we see that angles MNQ and RNM are linear angles, so we can say:
(3y - 9) + 156 = 180
3y - 9 = 24
3y = 33
y = 11
x = 18
y = 11

Step-by-step explanation:
please guys someone help i need the answer
Step-by-step explanation:
2x + y + x+ 2y = 180
3x + 3y = 180
3y +20+2x+y=180
4y + 2x = 160
3x + 3y = 180
2x + 4y = 160
elimination
6x + 6y= 360
6x + 12y = 480
= 6y = 120
y= 20
substitute
3x + 3y = 180
3x + 3(20)= 180
3x + 60 = 180
3x = 120
x= 40
x+2y
40+2(20)=80

What is the equation of the line that passes through the point (8,1) and has a slope
of –3/4?
Answer:
[tex]y=-\frac{3}{4}x+7[/tex]
Step-by-step explanation:
The slope is already given as [tex]-\frac{3}{4}[/tex] so all we have to do is solve for y-intercept
First, write the equation in slope-intercept form
[tex]y=-\frac{3}{4}x+b[/tex]
Next, use the point to substitute the x and y value and solve for the y-intercept
[tex]y=-\frac{3}{4} x+b[/tex] where b = y-intercept
point: (8, 1)
[tex]1=-\frac{3}{4}(8)+b[/tex]
Then multiply 8 and -3/4
[tex]1=-6+b[/tex]
Finally, solve for the b (y-intercept)
b = [tex]1--6[/tex]
b = 7
so the y-intercept is 7
And the equation of the line that passes through the point (8, 1) and has a slope of -3/4 is [tex]y=-\frac{3}{4}x+7[/tex]

I DONT KNOW WHAT THE ANSWER IS REALLY
If Caleb bought 1.2 pounds of cheese that was selling for 5.95 per pound. How much did Caleb pay for the cheese.
Answer:
$7.14
Step-by-step explanation:
If each pound of cheese is $5.95. You just have to find out how much 1.2 pounds is worth. So, you multiply 5.95 times 1.2 pounds and you'll get $7.14
Multiplication is the process of multiplying. The total amount that Caleb needs to make for 1.2 pounds of cheese at a rate of $5.95 per pound is $7.14.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that the rate of cheese per pound is $5.95 per pound. Therefore, the amount that Caleb needs to make for 1.2 pounds of cheese is,
Total Amount = $5.95/pound × 1.2 pounds
= $7.14
hence, the total amount that Caleb needs to make for 1.2 pounds of cheese at a rate of $5.95 per pound is $7.14.
