find the distance between (-3,-5) (4,8)
Answers
Answer:
14.765 units
Step-by-step explanation:
distance formula
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
d = √[(4 + 3)² + (8 + 5)²]
d = √(7²) + (13²)
d = √(49 + 169)
d = √218

HOPE IT HELPS (✷‿✷)
Answer:
[tex]\Huge \boxed{a_4=2}[/tex]
Step-by-step explanation:
The third term in an arithmetic sequence is 7.
The common difference is -5.
The common difference of an arithmetic sequence is found by subtracting a term in the sequence with the previous term.
[tex]d=a_4-a_3[/tex]
Solving for the fourth term.
[tex]a_4 = a_3 + d[/tex]
Plugging in the values and evaluating.
[tex]a_4=7+-5[/tex]
[tex]a_4=2[/tex]
The value of the fourth term is 2.

pls help me
Answers
Answer:
dy/dx = -b/a cot α
Step-by-step explanation:
x² / a² + y² / b² = 1
Take derivative with respect to x.
2x / a² + 2y / b² dy/dx = 0
2y / b² dy/dx = -2x / a²
dy/dx = -b²x / (a²y)
Substitute:
dy/dx = -b²a cos α / (a²b sin α)
dy/dx = -b cos α / (a sin α)
dy/dx = -b/a cot α
Jeremy spends 44 minutes eating dinner with his family. Jeremy finishes eating dinner at 6:09. What time did the clock show when Jeremy started eating dinner?
Answers
Answer:
5:25
Step-by-step explanation:
Borrow 1 hour from 6 hours, change it to 60 minutes, and add it to 9 minutes.
6:09 is the same as 5:69.
6:09 = 5:69
Now subtract 44 minutes from 69 minutes.
5:69 = 0:44 = 5:25

James truck shows that his average gas mileage per day is 29 miles per gallon of gas. If james drives about 87 miles each day about how much gas does he use in 14 days of driving
Answers
Answer: 42 gallons
Step-by-step explanation:
given data:
average gas mileage/day = 29miles/gallon
distance travelled each day by James = 87miles
How much gas does he use in 14days drive.
solution:
james drives 87miles daily, so in 14 days he would have travelled
= 87miles * 14
= 1218miles travelled.
gas used in 14days
1218miles distance traveled in 14 days
29miles/gallon
= 1218miles / 29miles
= 42gallons of gas have been used by janew to fuel his truck in 14days.

Answers
Answer:
-2x +18 or 18 - 2x
Step-by-step explanation:
You have 3x and you have -5x so take 5 away from 3 to get -2x
Then you have +8 and +10 so add them together and you get an answer of 18
Put the two answers from the equation together and you have got 18-2x
Hope this helps :)
Start by changing the problem to 3x + 8 + -5x + 10.
Combine like terms → your numbers and your "x" terms.
So 3x + -5x is -2x and 8 + 10 is 18.
So the answer is -2x + 18.

In triangle FGH, FG = 12.3 cm, GH = 10.6 cm, Measure of angle G = 80 degrees, and Measure of angle H = 55 degrees. If Triangle A B C is congruent to triangle G H F, which statement is true?
Answers
Answer:
AB = 10.6 cm
Step-by-step explanation:
In triangle FGH, FG = 12.3 cm, GH = 10.6 cm, m angle G=80 degrees, and m angle H=55 degrees. If triangle ABC GHF, which statement is true?
A. AB = 12.3 cm
B. AB = 10.6 cm
C. M angle C=55 degrees
D. M angle C=80 degrees
Answer:
If triangle ABC ≅ GHF, This means triangle ABC is congruent to triangle GHF.
Two triangles are congruent if the three sides and three angle of one triangle is equal to the three sides and three angle of the other triangle.
Hence the corresponding sides and angles of triangle FGH is equal to the corresponding side and angle of triangle ABC.
AB = GH
AB = 10.6 cm
m∠F + m∠G + m∠H = 180° (sum of angles in a triangle)
m∠F + 80 + 55 = 180
m∠F + 135 = 180
m∠F = 180 - 135 = 45
m∠F = 45°
m∠F = m∠C
m∠C = 45°

C. c = 7.75n
D. c = 7.75n + 25
Answers
Answer:
Option (B)
Step-by-step explanation:
If we graph the points given in the table, a straight line is obtained which shows that the table given represents a linear function.
Let the two points on the graph are (4, 31) and (8, 37)
Slope of the line passing through these points,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{37-31}{8-4}[/tex]
= 1.5
Equation of the line passing through a point (4, 31) and slope = 1.5 will be,
y - y' = m(x - x')
y - 31 = 1.5(x - 4)
y = 1.5x - 6 + 31
y = 1.5x + 25
Therefore, Option (B) will be the answer.

A cosmetics company tested a new lotion. Of the 2,500 people tested, 15 had an allergic reaction. What percent of the people tested did not have an allergic reaction to the new lotion?
Answers
Answer:
99.4%
Step-by-step explanation: 2500 - 15 = 2485
2485/2500 = 0.994 x 100 = 99.4%
Answer:
99.4%
Step-by-step explanation:
Total number of people tested = 2500
People who had allergic reaction = 15
People who didn't have allergic reaction = 2500 - 15 = 2485
Percentage = Part of a whole / The whole
=> 2485 / 2500
=> 497 / 500
=> .994
To convert a decimal into percent:
=> We need to make the decimal point move 2 times to the right
=> .994
=> 99.4%
So, 99.4% of the people who were tested, didn't have an allergic reaction.
what is 1 5/8 in decimal form?
Answers
Answer:
1.625

So you have to convert the 5/8ths into something that can go into 10.
So 100/8 is equivalent to 12.5. But you'll have to make that into decimal form, so move that 2 places to the right, to get 0.125. 0.125 times 5 is 0.625. And 1 is just 1 as a whole number. 1 plus 0.625 is 1.625.
The decimal form of the given number [tex]1\frac{5}{8}[/tex] is 1.625
What is the decimal form of a number?In Algebra, decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point.

Statements (1), (3), and (4) are correct these are NOT true after using the definition of the numbers.
What is the number?A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
As we know,
The integer can be defined as the whole number it can be a negative whole number or a positive whole number for example 2, 4, 1, -8, 0, etc.
It is defined as the numbers in all real numbers which cannot be represented as rational numbers, in other words, the irrational number cannot be expressed in the form of p/q form.
A rational number is a sort of real number that has the form p/q and does not equal zero.
Thus, statements (1), (3), and (4) are correct these are NOT true after using the definition of the numbers.

Two fair dice are tossed together once. Find the probability that the sum of the outcome is at least 10
Answers
Answer: p = 1/6.
Step-by-step explanation:
First, we have two fair dice, so we have two events.
The number of outcomes for each dice is 6, then the total number of outcomes for the two dice is equal to the product of the number of outcomes in each event.
C = 6*6 = 36.
Now, the combinations that have a sum larger than 10 are:
4 and 6.
6 and 4
5 and 5
5 and 6
6 and 5
6 and 6.
So we have 6 outcomes where the sum of both numbers is larger than 10.
Now, the probability will be equal to the quotient between the number of outcomes where the sum is larger or equal than 10, and the total number of outcomes:
P = 6/36 = 1/6.

The distributive property is a very important property used in algebra.
It states that when we have the statement a(b + c), we can "distribute" the
a by multiplying a times both terms that are inside the parenthses.
So that would give us a(b) + b(c) or ab + bc.
The same process is done here.
Distribute the 3 through both terms to get 3(x) - 3(1) or 3x - 3.
A 15 foot ladder is leaning against a wall. The foot of the ladder is 7 feet from the wall. How high up the wall is the ladder? Round to the nearest tenth if necessary.
Answers
Answer:
13.26
Step-by-step explanation:
The computation of the height should be computed by using the Pythagoras theorem
As we know that
Hypothenuse^2 = base^2 + height^2
where,
Hypothenuse is 15 foot
And, the foot of the ladder i.e base is 7
So now placing these values
The height is
15^2 = 7^2 + height^2
225= 49 + height^2
After solving this, the height is 13.26
Is 6837 cm less than, greater than or equal to 68hm
Answers
Answer:
6837 cm is less than 68 hm
Step-by-step explanation:
1 hectometres = 100 meters
1 centimetres = 0.01 meters
Therefore;
6837 centimetres = 6837 × 0.01 meters = 68.37 meter
6837 centimetres = 68.37 meter
Also, we have;
68 hectometres = 68 × 100 meters = 6800 meters
68 hectometres = 6800 meters
Therefore,
6837 centimetres = 68.37 meter < 68 hectometres = 6800 meters
6837 centimetres < 68 hectometres
6837 cm < 68 hm
6837 cm is less than 68 hm.
