Answer:

√85

Step-by-step explanation:

The distance formula tells you the distance between (x1, y1) and (x2, y2) is ...

... d = √((x2-x1)^2 +(y2-y1)^2)

For your points (-1, -4) and (-8, 2), the distance is ...

... d = √((-8 -(-1))^2 +(2 -(-4))^2) = √((-7)^2 +6^2) = √(49 +36)

... d = √85

The distance between the two points is √85.

Answer:

133*3+90*3+30*p

Step-by-step explanation:

add all that up then divide it by three

Answer:

p=43°

Step-by-step explanation:

We know that the sum of angles inside the triangle is 180 degree

One angle is P, we find other two angles

Angles in a straight line is 180 degree.

angle adjacent to 133 is 180-133=47

angle adjacent to 90 is 180-90=90

To find out P, we add all the angle and make it equal to 180 degree

p + 47+90= 180

p+137= 180

Subtract 137 on both sides

p=43°

Answer:

[tex]f(x)=8x^2+73x-70[/tex]

Step-by-step explanation:

We are given

zeros as -10 and 7/8

now, we can set up function as

[tex]f(x)=a(x-(-10))(x-\frac{7}{8})[/tex]

now, we are given that

leading coefficient is 8

so, a=8

now, we can plug it

[tex]f(x)=8(x-(-10))(x-\frac{7}{8})[/tex]

now, we can simplify it

[tex]f(x)=8\left(x^2+\frac{73x}{8}-\frac{35}{4}\right)[/tex]

so, we get

[tex]f(x)=8x^2+73x-70[/tex]

Solution:

[tex]\frac{3}{5}=\frac{6}{10}=\frac{9}{15}[/tex]

Two or more fractions are said to be equivalent , if reduced in lowest terms that is numerator and denominator are co-prime, they are equal.

Answer:

The range is  { -1,3,7,11,15}

Step-by-step explanation:

The range is just the output values

f(-2) = 4(-2) +7 = -8+7 =-1

f(-1) = 4(-1) +7 = -4+7 = 3

f(0)= 4(0) +7 = 7

First you should make a table to explain it better to yourself. Make 2 columns named Domain(Input) and Range(Output). Now put your ordered pair in the range area. Now calculated the function by replacing X with the range. Calculate.

The set of all possible vectors you can reach with the linear combination of two vectors is called the linear span of the set of two vectors.  

We often write the span of a set of vectors S as span(S) and it's itself a vector space, a subspace of the vector space from which the elements of S are drawn.

Answer:

I think you can also call it a vector space.

Step-by-step explanation:

1. PQ║TS, PQ ≅ TS, PT and QS are transversals to the parallel lines . . . given

2. ∠P ≅ ∠T . . . alternate interior angles at PT

3. ∠Q ≅ ∠S . . . alternate interior angles at QS

4. ΔPQR ≅ ΔTSR . . . ASA postulate

_____

You can use any pair of angles together with the sides PQ and TS. If you use the vertical angles and one of ∠T or ∠S, then you must invoke the AAS postulate for congruence, as the side is not between the two angles.

Answer:

10. It is a parallelogram.

11. The parallelogram is a rhombus.

Step-by-step explanation:

10. Use the given sets of congruent segments with congruent vertical angles XNY and WNZ to prove that triangles XNY and ZNW are congruent. Now use CPCTC to show that angles XYN and ZWN are congruent. They are alternate interior angles making sides XY and WZ parallel. Now use CPCTC to show that sides XY and WZ are congruent. Since a quadrilateral has two opposite sides that are both parallel and congruent, the quadrilateral is a parallelogram.

11. A rectangle and a square have 4 right angles. If you add 72 deg and 72 deg, you get 144 deg which is not a right angle. Since one angle of the parallelogram is not a right angle, the parallelogram is not a square or a rectangle.

There are two triangles. Let's look at the upper triangle. The triangle has 2 angles measuring 72 deg each. That means the opposite sides are congruent, and the triangle is isosceles. Since the quadrilateral is a parallelogram, opposite sides are congruent, so all 4 sides are congruent, and the parallelogram is a rhombus.

10. It is a parallelogram.

Answer:

-5+√3i  is the given root so -5-√3i  must be the other root

Step-by-step explanation:

We know that complex roots must come in pairs. The pairs are complex conjugates.  (a+bi)  and (a-bi)

You are missing a sign between -5 and the square root

So if - 5+ sqrt(3) i  is a root, then -5 - sqrt(3) i   must be a root  

if -5 - sqrt(3)i   is a root, then -5 + sqrt(3)i   must be a root.

I will assume you missed a + sign

-5+√3i  is the given root so -5-√3i  must be the other root

Step-by-step explanation:

Answer:

27,600

Step-by-step explanation:

We use the following formula:-  

Number of permutations of r from n

= nPr

= n! / (n-r)!

I am assuming you don't allow repeated letters in the 4 letter codes.

Take S as the first letter. Then we have 3 letters extra out of 25 letters.

Using the above formula the possible ways of doing this is

25! / (25 - 3)!

25! / 22!

= 25*24*23

= 13800.

The same number is obtained if the first letter is a T.

So the answer is 2*13800

= 27,600

Answer:

12x² -27x + 13

Step-by-step explanation:

First of all, expand the first two brackets and put the correlating values near each other:

10x² + 5x² -19x -8x -2 +13

10x² + 5x² = 15x²

-19x + - 8x = -27x

-2 + 13 = 11

15x² - 27x + 11

Now, subtract the values inside the third bracket:

15x² - 3x² = 12x²

11 - -2 = 11 + 2 = 13

So the end result is:

12x² -27x + 13

Answer:

Can not be determined.

Step-by-step explanation:

We can easily notice that the limit is x tends to infinity, whereas x is not present in the given function, we are given (1 + 1/n). So we can not evaluate the given limit for x as parameter, we must have some function of x to solve this problem.

Hence, option C is correct i.e. the limit can not be determined.

Answer:

78*50/100= 78/2 ( half of 78) = 39

Step-by-step explanation:

Answer:

1.A. 88.89

2.B.6.3%

3.C.64.92%

Step-by-step explanation:

1.[tex]\frac{8}{9}=0.8888[/tex]

to covert it into percentage multiply it with 100

then it becomes 88.888

rounding off to the nearest hundred it becomes 88.89

2. to convert into percentage multiply it with 100

therefore 0.063×100=6.3%

3. to find percentage

    %= (no of students using mobile / total no of students )× 100

       = [tex]\frac{792}{1200}[/tex]×100

       =64.918

Rounding off to nearest hundred it becomes 64.92%

Answer:

1) A. 88.89%

2) B. 6.3%

3) C. 64.92%

Step-by-step explanation:

1) After dividing 8 by 9, we get, [tex]\frac{8}{9} = 0.8889[/tex].

Now, percent of [tex]\frac{8}{9}[/tex] = 0.8889 * 100 = 88.89%

Hence, percent to nearest hundredth is 88.89%

2) We want 0.063 to be written in percent form

i.e. 0.063 * 100 = 6.3%

Hence, 0.063 into percent form is 6.3%

3) We are given that the total number of students are 1220 and the number of students that have cell phones are 792.

Therefore, the percent of students having cell phones = [tex]\frac{792}{1220} *100[/tex] = 64.92%

Hence, the percent of students having cell phones to nearest hundereth is 64.92%

B) 6 hours

Let h represent the total trip time. Then h/2 is the time spent traveling at each speed. The distance covered is ...

... distance = speed · time

The sum of the distances in each mode is the total distance.

... 1020 = 55·h/2 +285·h/2

... 2040 = h·(55+285) . . . . multiply by 2

... 2040/340 = h = 6 . . . . . . . divide by the coefficient of h

The trip took a total of 6 hours.

Problem-solving is defining a problem; figuring out the purpose of the trouble; identifying, prioritizing, and selecting alternatives for an answer; and imposing an answer.

Problem-solving starts with identifying the issue. For example, a trainer may need to figure out a way to improve a scholar's overall performance on a writing talent test. To do that, the instructor will overview the writing exams looking for regions for improvement.

Calculation:-

Quantity of water Olivia took = half a gallon i.e 0.5 gallons.

Quantity of water Olivia drank =0.75 of 0.5

      ∴  75% of 0.5 gallons

          = 75/100 × 0.5

           = 0.375 gallons.
