Can someone please help me on this question

Answer:

Angle A = 102°

Angle B = 51°

Angle C = 27°

Step-by-step explanation:

angle A = 2b

angle B = b

angle C = 1/3 b + 10

Angle A + Angle B + Angle C = 180

2b + b + 1/3 b + 10 = 180

3 1/3 b + 10 = 180

10/3 b = 170

b = 51

a = 2b = 102

c = 1/3 b + 10 = 1/3 (51) + 10 = 17 + 10 = 27

Answer:

f'(x) = (x + 1)/15

Step-by-step explanation:

f(x) = 15x -1,

Think of the term "f(x)" as a single variable, then solve for the term "x", manipulate the equation like how one would manipulate a literal equation, by inverse operations.

f(x) = 15x - 1

+1            +1

f(x) + 1 = 15x

/15         /15

(f(x) + 1)/15 = x

This means that (denote in the way one would denote an inverse of a function);

f'(x) = (x + 1)/15

Answer:

D. x2 = 52 + 32 – 2(5)(3)cos(140°)

Step-by-step explanation:

The equation measures the cyclist's distance, x, from the starting point will be x²=5²+3²-2(5)(3)cos(140°). Option B is corect.

Distance is a numerical representation of the distance between two objects or locations.

The distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.

Distance is measured in the meter, centimeter, miles, nautical mile, feet, etc. The unit of distance is most important to find it.

The distance, x, from the starting point is;

From the cos law ;

x² = a² +b²-2ab cosΘ

From the digrame it is obtained that;

a =5

b =3

Θ = 180 ° +70° -30°

Θ = 180°- 40°

Θ = 140°

Substitute the values;

x² = a² +b²-2ab cosΘ

x²=5²+3²-2(5)(3)cos(140°)

The equation measures the cyclist's distance, x, from the starting point will be x²=5²+3²-2(5)(3)cos(140°).

Hence option B is corect.

Answer:

The length of EF = x = 18 cm

Option A is correct.

Step-by-step explanation:

Ware given perimeter of triangle = 97 cm

We need to find length of EF = x = ?

The length of EG = x+7

The length of EF = x

The length of GF = 3x

The formula used is: [tex]Periemter \ of \ triangle= Sum \ of \ all \ sides \ of \ triangle[/tex]

Putting values and finding x i.e length of EF

[tex]Periemter \ of \ triangle= Sum \ of \ all \ sides \ of \ triangle\\97=x+7+x+3x\\97-7=5x\\5x=90\\x=\frac{90}{5}\\x=18 \ cm[/tex]

So, value of x=18 cm

The length of EF = x = 18 cm

Option A is correct.

Answer:

The answer is below

Step-by-step explanation:

We need to prove that:

(Root of Sec A - 1 / Root of Sec A + 1) + (Root of Sec A + 1 / Root of Sec A - 1) = 2 cosec A.

Firstly, 1 / cos A = sec A, 1 / sin A = cosec A and tanA = sinA / cosA.

Also, 1 + tan²A = sec²A; sec²A - 1 = tan²A

[tex]\frac{\sqrt{secA-1} }{\sqrt{secA+1} } +\frac{\sqrt{secA+1} }{\sqrt{secA-1} } =\frac{(\sqrt{secA-1)}(\sqrt{secA-1})+(\sqrt{secA+1)}(\sqrt{secA+1}) }{(\sqrt{secA+1})(\sqrt{secA-1}) } \\\\=\frac{secA-1+(secA+1)}{\sqrt{sec^2A-secA+secA-1} } \\\\=\frac{2secA}{\sqrt{sec^2A-1} } \\\\=\frac{2secA}{\sqrt{tan^2A} } \\\\=\frac{2secA}{tanA} \\\\=\frac{2*\frac{1}{cosA} }{\frac{sinA}{cosA} }\\\\= 2*\frac{1}{cosA}*\frac{cosA}{sinA}\\\\=2*\frac{1}{sinAA}\\\\=2cosecA[/tex]

Answer:

x = -1

Step-by-step explanation:

-2+3x=-(x+6) distrbute the negative

-2+3x=-x-6 combine liked terms (added x & 2 to each side)

+2 +x   +x  +2

4x = -4 isolate x (divide 4 from each side)

x = -1

Answer:

X=-1

Step-by-step explanation:

First, add 2 on both sides to eliminate -2 and to get 3x alone. Now you have the product of 3x=-x-4. Next, add x on both sides to isolate negative 4. Once, you have done this you get 4x=-4. Now you divide by 4 to get x alone. And you get the product x= -1.

The actual image of the parallelogram has been translated by 6 units left and 2 units down of the preimage parallelogram.

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

Reflection is a mirror image of a graph about any axis.

Given the preimage of a parallelogram with vertices (1,5), (3,3), (3,7), and (5,5).

If we plot in the coordinate plane as shown below.

Now plot the image of a parallelogram with vertices (−5,3), (−3,1), (−3,5), and (−1,3).

If we take only one vertex of the preimage to let's say (1,5) now if we look at the corresponding vertex in the image then it is (-5,3).

1 + x = -5 ⇒ x = -6 (6 units left)

5 + y = 3 ⇒ y = -2 (2 units down)

Hence "The actual image of the parallelogram has been translated by 6 units left and 2 units down of the preimage parallelogram".

Answer:

Answer:

Step-by-step explanation:

Half the area of the rectangle shown is 24 square inches. Then value of x is 6

The area of Rectangle is length times of width.

Area = length x width.

24 = (x + 2)(x - 3) = x² - x - 6

x² - x - 30 = 0

(x + 5)(x - 6) = 0

We can eliminate the root x = - 5 because dimensions cannot be negative. So, the only valid answer is x = 6

The length = x + 2 = 6 + 2 = 8 in.

The width = x - 3 = 6 - 3 = 3 in

Hence, the value of x is 6.

Answer:

d > 6 3/4

Step-by-step explanation:

Given that:

72 hot dogs in 10 minutes is required to break Record ;

Consumption after 1 minute = 11 1/4 hot dogs

Number of hotdogs consumed per minute for the next 9 minutes = d

Number of consumption per minute required to break record :

d = (72 - 11 1/4) / 9

d = (60 3/4) ÷ 9

d = (243 / 4) * 1/9

d = 243 / 36

d = 6 3/4 hotdogs per minute

Hence, to break record. Consumption must be > 72 hotdogs in 10 minutes

Hence,

d > 6 3/4

Answer:

The indifference point is 100 minutes.

Step-by-step explanation:

Giving the following information:

Plan a cost $23 plus an additional $.08 for each minute of calls.

Plan B cost $19 an additional $.12 for each minute of calls.

First, we need to establish the total cost formula for each plan:

Plan A= 23 + 0.08*x

Plan B= 19 + 0.12*x

x= number of minutes

Now, to calculate the indifference point, we equal both formulas and isolate x:

23 + 0.08x = 19 + 0.12x

4 = 0.04x

100= x

The indifference point is 100 minutes.

Prove:

Plan A= 23 + 0.08*100= $31

Plan B= 19 + 0.12*100= $31
