The sum of the natural numbers is (a) 25
How to determine the sum of the natural numbers?From the question, we have the following parameters that can be used in our computation:
Number type = natural number
Condition = 5 times bigger than their last digit
This means that
Number = 5 * Last digit
Because the number is a natural number, then the number cannot end in 0
This is so because 0 is not a natural number
Solving further, the last digit of the number is at most, 9
Using the above as a guide, we have the following:
The number is at most 45 i.e. 5 * 9
Also, it means that it can not have more than 2 digits.
The above highlights in a nutshell is that the number is a multiple of 5 that does not end in 0 and the last digit is 5
Since the last digit is 5, then we have the number to be 25 i.e. 5 * 5
Hence, the number is (a) 25

Solve using the quadratic formula. Show all work. Write each solution in simplest form. No decimals.
Answer:
A) -2 - i√3 , -2 + i√3
Step-by-step explanation:
Solve using quadratic formula
x² + 4x + 7 = 0
The Almighty Formula
= -b ± √b² - 4ac/2a
Where ax + bx² + c = 0
From the above question
a = 1, b = 4, c= 7
Hence,
-4 ± √4² - 4 × 1 × 7/2 × 1
-4 ± √16 - 28/2
=( -4 ± √-12)/2
Since
b² - 4ac < 0
We have two complex roots
Simplifying
( -4 ± √-12)/2
= -4/2 ± √-12/2
= -2 ± 2√3i/2
= -2 ± √3i
Therefore,
-2 - √3i , -2 + √3i
or
-2 - i√3 , -2 + i√3

What is equation?An equation is a mathematical formula that expresses equality by joining two expressions together with the equal symbol =. The definition of an equation in algebra is a mathematical statement proving the equality of two mathematical expressions. In the equation 3x + 5 = 14, for instance, the terms 3x + 5 and 14 are separated by an equal sign. An equal sign is a part of all mathematical formulas, including equations. Often, algebra is used in equations. In mathematics, algebra is employed when we don't know the precise quantity to calculate
Here,
Heat's characteristics
The direction of this transmission is always determined by the temperature differential between the bodies.
To achieve an equilibrium temperature, heat is transferred from the hotter to the cooler body.
As a result of the fact that a body and its surrounds are at different temperatures, we can infer that heat is the energy that is transferred between them.

Liam Brought 5/8 Pound of cherries. Harrison Brought more cherries than Liam. Which could be the amountOf cherries that Harrison brought ?
The amount of cherries bought by the Harrison is 62.5 pounds.
A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator.
The amount of cherries bought by the Harrison should be more than the cherries bought by the Liam which is 5/8. Thus, The amount of cherries bought by the Harrison is more than the 5/8 or 62.5 pounds of cherries percent.
The cherries bought by the Liam is 5/8 pounds
The cherries bought by the Harrison is more than the Liam.
As in the problem the number of cherries bought Harrison (let) should be more than the cherries bought by the Liam (let ). Therefore,
H > L
As we know that the number of cherries bought by the Liam is 5/8 pounds. Keep the value of in the above equation, we get,
H > 5/8
This equation can be rewritten in the percentile form as,
h > (5/8) * 100 %
h > (5/2) * 25 %
h > 62.5 %
Hence, The amount of cherries bought by the Harrison is more than 5/8 pounds or 62.5 pounds of cherries percent.

Write an equation of the line passing through the point (1,8) and parallel to y=−3x+10
The equation of the line is 3x + y - 11 = 0.
The slope-intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y intercept (0, b). In the formula, b represents the y value of the y intercept point.
First we find the slope of the line y=-3x+10 by placing it into slope-intercept form:
y = -3 x + 10
Therefore, the slope of the line is m= -3
Now since the equation of the line with slope m passing through a point
(x₁ ,y₁) is y-y₁ = m(x-x₁)
Here the point is (1,8) and slope is m= -3, therefore, the equation of the line is:
y - 8 = -3(x - 1)
y - 8 = -3x +3
3x + y - 11 = 0
Hence, the equation of the line is 3x + y - 11 = 0.

If f(x) = x5 - 1, g(x) = 5x², and h(x) = 2x, which expression is equivalent to [go fo h](9)?
O2(5(95-1)²)
O2((5-92)5-1)
O5((2-9)5-1)²
O(5(2-9)2)5-1
The response to the given domain range questions is [go f oh]. (9) = 5(18^2 - 1 )
What are the domain and range?Domain and range. A function's authorised range of values is known as its domain. The x values in a function like f make up this set (x). A function's range is the collection of values that it can take as input. When we enter an x value, the function outputs this set of values.
According to the given information:f(x) = x^5 – 1, g(x) = 5x^2, and h(x) = 2x
[g o f o h](9)=g(f(h(9))
Let's find h(9) first
h(x)= 2x
h(9)= 2(9) =18
Now plug in 18 for h(9)
[g o f o h](9)=g(f(h(9)) = g(f(18))
now we find f(18)
f(x) = x^5 – 1, f(18)= 18^5 -1
Now we plug in 18^5 -1 for f(18)
[g o f o h](9)=g(f(h(9)) = g(18^5 -1)
Plug it in g(x)
g(x)= 5x^2

Jupiter is about 5. 2 Astronomical Units (AU) from the Sun. Neptune is about 30. 1 AU from the sun. How many times as far from the Sun is Neptune as Jupiter? First answer gets brainliest
If Jupiter is about 5.2 Astronomical Units (AU) from the Sun and Neptune is about 30.1 AU from the Sun, Neptune is about 5.79 times far from the Sun as Jupiter.
Therefore the answer is 5.79.
To find how many times as far from the Sun Neptune is as Jupiter, we need to divide the distance from the Sun to Neptune by the distance from the Sun to Jupiter.
Neptune is about 30.1 AU from the Sun and Jupiter is about 5.2 AU from the Sun, so:
= Distance from the Sun to Neptune / Distance from the Sun to Jupiter
= 30.1 / 5.2
= 5.79
So, Neptune is about 5.78 times as far from the Sun as Jupiter.
