Answer 1

Answer:

270°

Step-by-step explanation:

∠ PQR = 90° ( angle in a semicircle )

PRST is a cyclic quadrilateral

The opposite angles in a cyclic quadrilateral are supplementary, sum to 180°

Then

∠ PRS + ∠ PTS = 180°

∠ PQR + ∠ PRS + ∠ PTS = 90° + 180° = 270°

if the output number y is -52 (y=5x-2) what is the input number? SHOW WORK

Answers

Answer:

-10

Step-by-step explanation:

The 'y' variable is associated with outputs and the 'x' variable is associated with inputs.

[tex]y = 5x-2\\\rule{150}{0.5}\\-52 = 5x - 2\\\\-52 + 2 =5x - 2 + 2\\\\-50 = 5x\\\\\frac{-50=5x}{5}\\\\\boxed{-10 = x}[/tex]

-10 (x) should be the input number.

Answer:

x = -10

Step-by-step explanation:

Equation:

-52 = 5x - 2 [tex]\longmapsto[/tex] Add 2 to both sides

-50 = 5x [tex]\longmapsto[/tex] Divide both sides by 10

x = -10

Answer:

[tex]f(x)=-11\times(7^x^-^1)[/tex]

Step-by-step explanation:

Stare at the numbers. Especially the first two. First one is -11. Second is [tex]-11\times 7[/tex]. Let's guess you keep multiplying. [tex]-77\times 7=-539[/tex]. Smells correct, let's confirm with the last one: [tex]-539\times7 = -3773[/tex]. I think we found a pattern. Each element is 7 times the previous one. With some practice you can just write the function, else let's divide by -11 away and let's see what we get:

[tex]f(1) = 1=7^0; f(2)=7; f(3)=7^2; f(4)=7^3[/tex]. Basically, the exponent is 1 less than the value we're evaluating the function. That leads tho the following

[tex]f(x)=-11\times(7^x^-^1)[/tex]

Jim sells used drones for 70% of the original manufacturer's purchase price of a new drone. Jim also sells new drones for 15% more than the manufacturer's purchase price of a new drone. write a function to determine the total amount a customer saves if they purchase a used drone rather than a new drone from Jim's store. let x represent the manufacturer's purchase price of the drone

Answers

The function for the amount saved if they purchase a used drone rather than a new drone from Jim's store is f(x) = 0.45x

He sells used drones at 70% of the price (x).

So, the selling price of a used drone is:

[tex]\mathbf{Used = 70\% \times x}[/tex]

Express percentage as decimal

[tex]\mathbf{Used = 0.7 \times x}[/tex]

[tex]\mathbf{Used = 0.7x}[/tex]

Also, he sells new drones at 15% more of the price (x).

So, the selling price of a new drone is:

[tex]\mathbf{New= (1 + 15\%) \times x}[/tex]

Express percentage as decimal

[tex]\mathbf{New= (1 + 0.15) \times x}[/tex]

[tex]\mathbf{New= 1.15 \times x}[/tex]

[tex]\mathbf{New= 1.15x}[/tex]

The amount saved is the difference between the prices of the drones.

So, we have:

[tex]\mathbf{Saved =New - Old}[/tex]

This gives

[tex]\mathbf{Saved =1.15x- 0.7x}[/tex]

Subtract

[tex]\mathbf{Saved =0.45x}[/tex]

Express as a function

[tex]\mathbf{f(x) = 0.45x}[/tex]

Hence, the function for the amount saved is f(x) = 0.45x

The expression that represents the required distance is [tex]\mathbf{ s = \frac{h}{0.5878}}[/tex]

The given parameters are:

[tex]\mathbf{\theta =36^o}[/tex] --- the angle of elevation to the top of the tree

To do this, we make use of the following representations

s represents the distance from the tip of the shadow to the top of the treeh represents the height of the tree

The distance (s) is then calculated using the following sine ratio

[tex]\mathbf{ sin(\theta) = \frac{h}{s}}[/tex]

Make s the subject

[tex]\mathbf{ s = \frac{h}{sin(\theta)}}[/tex]

Substitute [tex]\mathbf{\theta =36^o}[/tex]

[tex]\mathbf{ s = \frac{h}{sin(36)}}[/tex]

Evaluate sin(36)

[tex]\mathbf{ s = \frac{h}{0.5878}}[/tex]

The height of the tree is not known.

Answers

Answer:

81/256

Step-by-step explanation:

The exponent 4 is meaning how many times you have to multiply a number it is on top of.

So you need to multiply 3/4, 4 times by itself

3/4* 3/4* 3/4* 3/4

3 times 3 times 3 times 3 is 81

4 times 4 times 4 times 4 is 256

So the answer is 81/256
