Even though scientists can't directly observe what is happening on Mars, they can send satellites to orbit Mars which can document the various aspects of Mars and its geography.
How can we observe Mars?Thanks to massive strides in space technology, humans have been able to study Mars all the way from Earth without having to observe the planet directly.
The main way they can do this is by positioning satellites around Mars which will orbit the planet. These satellites will record and observe things such as the composition of the atmosphere of Mars and how its terrain works.
In conclusion, scientists can use satellites to observe Mars.

Find the equation of the graph
Find the average rate of change from x = 5 to x = 7
Answer: y=-(x-6)(x-8)
Average rate of change: 2
Step-by-step explanation:
Graph facing downward, so equation is negative
Since the equation is quadratic, the degree is 2.
When you look at the graph, you see the values of x when y=0
x=6 ==> y=0
x=8 ==> y=0
Equation: y=-(x-6)(x-8) ==> add the negative sign to show the equation is going down.
x=5 ==> y=-3 ==> (5, -3)
x=7 ==> y=1 ==> (7, 1)
Slope formula: m=(y2-y1)/(x2-x1)
m=(1-(-3))/(7-5)
m=(1+3)/(2)
m=4/2
m=2 ==> average rate of change
If m∠FDE = (3x−15)° m∠FDE = 3x-15° and m∠FDB = (5x+59)°, find the value of x such that ∠FDE and ∠FDB are supplementary.
The value of x is x = 18.25
How to determine the value of x?The angles are given as
m∠FDE = 3x-15° and m∠FDB = (5x+59)°
The angles are supplementary angles
FDE + FDB = 180
This gives
3x - 15 + 5x + 59 = 180
Evaluate the like terms
8x = 146
Divide by 8
x = 18.25
Hence, the value of x is x = 18.25

in a classroom there are 56 boys and 72 girls, find the ratio of girls to the total number of students.
Answer: [tex]\frac{9}{16}[/tex]
Step-by-step explanation:
We need to find the ratio of girls to the total number of students. That means our ratio is going to be 72 (the number of girls) over 56+72 (boys + girls, the total number of students).
When you add 56+72, you'll get 128 in the denominator. Continuing to simplify the fraction, you'll end up with:
[tex]\frac{72}{128}[/tex] = [tex]\frac{9}{16}[/tex]
Depending on what format your teacher wants, this can be written as [tex]\frac{9}{16}[/tex] or 9:16.

Applying the vertical angles theorem, we have:
x = 29
z = 13
How to Apply the Vertical Angles Theorem?Based on the vertical angles theorem, the vertical angles AIZ and GIM are congruent to each other.
Therefore:
7. m<AIZ = m<GIM
Substitute
3x - 56 = x + 2
3x - x = 56 + 2
2x = 58
x = 29
8. 4z + 7 + x + 2 = 90 (complementary angles)
Plug in the value of x
4z + 7 + 29 + 2 = 90
4z + 38 = 90
4z = 90 - 38
4z = 52
z = 52/4
z = 13

What is the solution for an equation?The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of those variable would give a true mathematical statement.
The Solution to an equation is finding values of the variable included in the considered equation for which the equation considered evaluates to be true.
For a solution to a system, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs, so solution to a system is the intersection of all its equation at single point
The expression is y = 5x-3
We need to determine the output y, when the value of input is x is 5 so
That is, substituting in , we get the following;

At the beginning of the month, you have $1500 in your bank account. Each time you visit the ATM you take $60 out of your account. Last month you lent your friend $50.
What is the rate at which your balance is changing each time you visit the ATM?
The required expression of the rate at which the balance is changing each time is 1450 - 60x, where x is the number of visits to the ATM.
Here,
At the beginning of the month, you have $1500 in your bank account.
Each time you visit the ATM you take $60 out of your account.
Rate of money out = 60x, where x is the number of times atm visit.
Last month you lent your friend $50.
Money left = 1500 - 50 - 60x = 1450 - 60x
Thus, the required expression of the rate at which the balance is changing each time is 1450 - 60x, where x is the number of visits to the ATM.

Taking into account the greatest common divisor, the greatest number of flowers in each group is 20.
Greatest common divisorThe greatest common divisor is the largest number that exactly divides two or more numbers at the same time.
To calculate the greatest common multiple, follow these steps:
Decompose each number into prime factors (numbers that are only divisible by themselves or by the number 1).Next, the factors common to the numbers are chosen.Next, in each of the commons, the factor with the smallest exponent is chosen.Finally, the chosen factors are multiplied.In summary, the common factors (those that are repeated) are multiplied with their smallest exponent.

The equation that can be used to determine the cost of one drink is 2x = 6.09
The sum of the prices for the movie tickets, refreshments, and voucher represents the total sum that Stephen and Paul will be required to pay.
Therefore,
The total amount paid is equal to the cost of two tickets + cost of the two drinks - coupon
So,
( 11 × 2 ) + ( x × 2 ) - 5 = 29.18
22 + 2x - 5 = 29.18
Subtracting 22 from each side of the equation.
22 + 2x - 5 - 22 = 29.18 - $22
2x - 5 = 7.18
Adding 5 on each side of the equation.
2x - 5 + 5 = 7.18 + 5
2x = 12.18
Now, divide each side of the equation by 2.
x = 6.09
Hence, the cost of one drink is $6.09

D. $136.19
E.
The charity expects a donation of D. 136.19 dollars from Eduardo, Becky, and Martin.
What is a fraction?Fractions describe how many parts of something is there to the total part.
To obtain how much each individual donated we have to multiply the fraction of donation to the amount of money they saved and take the sum.
Eduardo donated 2/7 of his savings which is (2/7)×150 dollars.
= 42.85 dollars.
Martin donated 2/9 of his savings which is (2/9)×150 dollars.
= 33.33 dollars.
Becky donated 2/5 of his savings which is (2/5)×150 dollars.
= 60 dollars.
∴ The total money they donated is ( 42.85 + 33.33 + 60 ) dollars.
= 136.18 dollars.

Answer:
[tex]Domain: \;\boxed{-4 } < x \le 4\\\\Ramge: \boxed{-2} \le y < 5[/tex]
Step-by-step explanation:
Domain
Domain is the set of all valid x values for the function
Looking at the graph we see that the function x values go from x- 4 to x = +4.
Note the unfilled circle at x = -4, y = 5. This means that this point is not included in any set of values that we intend tp find. It will represent a < or > inequality.
A filled circle means that value is included
So the domain of the function is -4 < x ≤ 4 (note that -4 is not included in the domain
Range
The range is the set of all y values for the entire domain. Basically it is defined using the min and max values that y can take
The minimum y value occurs at x = 4 and y is -2 (this is included because of the filled circle)
The max value occurs at x = -4 and the value of y here is 5 (5 is not included)
Therefore the range is -2 ≤ y < 5

[tex] \frac{8x}{8} = \frac{152}{8} \\ x = 19[/tex]
Answer:
x=26
Step-by-step explanation:
since we are adding, you start by combining like terms. x's with x's and #'s with #'s. that leaves you with 8x-28=180. Your next step is to get x all by itself so you move the -28 to the other side by adding 28 to both parts. that leaves you with 8x=208. now you still have to get x by itself and right now its being multiplied with the 8 so to get rid of it you divide by 8 on both sides and that leaves you with x=26.

What is Prime factorization ?
Prime factorization is defined as a way of finding the prime factors of a number, such that the original number is evenly divisible by these factors. As we know, a composite number has more than two factors, therefore, this method is applicable only for composite numbers and not for prime numbers.
Prime factors of 2020 = 2,2,5,101
