Based on the temperature readings, the average recorded temperature in the 20 days was 10.15°

The average temperature can be found by adding all the temperatures and then dividing by the number of temperatures taken which is 20.

The average is therefore:

Explanation:

The length of the segment is 10 plus 5 which is fifteen because you need to know how long it is. Just ignore the negatives.

The quotient of the given problem using laws of exponents is; 6 * 10⁰

We want to express the quotient of the quantity 30 times ten raised to the negative twenty fourth power end quantity divided by the quantity 5 times ten raised to the negative twenty fourth power end quantity.

This is;

(30 * 10⁻²⁴)/(5 * 10⁻²⁴)

Now, we can break this down into like terms to get;

(30/5) * (10⁻²⁴/10⁻²⁴)

= 6 * 1

The vehicle will get speed of approximately 15 mph and -210 mph.

Science's most important concept is measurement. Many measurable quantities are measured in fundamental or base units. One such measurable quantity is speed, which is defined as the ratio of an object's distance travelled to the time required to travel that distance. Let us learn about speed in depth during this session.

The ratio of distance to time taken to cover a distance is used to calculate speed. Because it only has one direction and no magnitude, speed is a scalar quantity.

Given the equation for gas mileage = 0.02x² + 3.9x  - 43 where x means speed

We have been asked to find x if gas mileage = 20 that is

0.02x² + 3.9x  - 43 = 20

Lets simplify

⇒ 0.02x² + 3.9x  - 43 = 20

⇒ x² /50 + 39x/10  - 63 = 0

⇒ x²/ 50 + 195x/50 - 3150 = 0

⇒ 1/50 (x + 195x - 3150 ) = 0

⇒ 1/50 (x + 210x - 15 x - 3150 ) = 0

⇒ 1/50 (x (x+210) −15 (x+210)) = 0

⇒ 1/50 (x−15)(x+210) = 0

⇒  (x−15)(x+210)  = 0 × 50

⇒ (x − 15)(x + 210)  = 0

⇒ x = 15, x = -210

So, try using 15 mph and -210 mph, that might work.

Step-by-step explanation:

This is because they are supplementary angles! I hope this helps. Xx

Answer: ∠1 = 90°

Step-by-step explanation:

∠1 = ∠4

∠2 = ∠5

∠3 = ∠6

reason = vertically opposite angle

∠1 = 90°

∠2 = 58°

∠3 = 32°

checking :

total angles = 360°

360° = ∠1 + ∠2 + ∠3 + ∠4 + ∠5 + ∠6

The area of the polygon is approximately 24.497 square units.

In accordance with the statement, we have a polygon with three vertices set on Cartesian plane, that is, a triangle. We need to find the side lengths first and later to calculate the area by Heron's formula. First, determine the lengths of each line segment by Pythagorean theorem:

JK = √[[4 - (- 3)]² + (4 - 4)²]

JK = 7

KL = √[(3 - 4)² + (- 3 - 4)²]

KL = √[(- 1)² + (- 7)²]

KL = 5√2

JL = √[[3 - (- 3)]² + (- 3 - 4)²]

JL = √85

Second, calculate the area of the triangle:

s = (JK + KL + JL) / 2

s = (7 + 5√2 + √85) / 2

s ≈ 11.645

A = √[s · (s - JK) · (s - KL) · (s - JL)]

A = √[11.645 · (11.645 - 7) · (11.645 - 5√2) · (11.645 - √85)]

A ≈ 24.497

The area of the polygon is approximately 24.497 square units.

The solution set of the inequality for R is given by [tex]-\frac{1172}{85} \leq x\leq \frac{1228}{55}[/tex] .

An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way.  It is frequently used to compare two numbers on the number line based on their sizes. Different types of inequalities are represented by a variety of notations such as < ,> ,≤ and ≥.

The modulus function takes the absolute value of a function.

To solve the given inequality we have simplify the inequality first.

[tex]x-\frac{7}{9} |(\frac{12}{5} -6x)|+50\ge -30[/tex]

[tex]or, x-\frac{7}{9}\times \frac{6}{5} |(2-5x)|+50\ge -30\\or,x-\frac{14}{15}|2-5x|\ge-80\\[/tex]

Now we separate the inequalities:

[tex]x-\frac{14}{15}(2-5x)\ge-80[/tex]  for 2x-5 ≥ 0

[tex]x-\frac{14}{15}(-(2-5x))\ge-80[/tex]  for 2x-5 ≤ 0

Now we will solve the two inequalities separate and find the intersection.

[tex]x-\frac{14}{15}(2-5x)\ge-80\\or,15x-28+70x\ge-1200\\or,x\ge -\frac{1172}{85}[/tex]

Again

2x-5 ≥ 0

or, [tex]x\le\frac{2}{5}[/tex]

hence [tex]-\frac{1172}{85}\le x\le\frac{2}{5}[/tex]

Similarly solving the other inequality we get

[tex]\frac{2}{5}\le x\le\frac{1228}{55}[/tex]

Now we find the intersection of the two inequalities:

[tex]-\frac{1172}{85}\le x\le\frac{1228}{55}[/tex]

Given that 19th term of the sequence is:

         gn=gn−1⋅(−12) if g17=162

Suppose a=12

Then,

The 17th term g17=a+(n-1)d

                           = 12+(17-1)d

'n' means number of terms

                        12+(17-1)d=162    because g17=162

                        12+16d=162

                         16d=162-12

Subtract the values,

We can write,

                         16d=150

                           d=150/16

Divide the values,

We can write,
