Answer:
x = -11 5/17
Step-by-step explanation:
3x + 2y = 12
2x - 3y = -57
5x + y = -45
y = -5x - 45
2x - 3 (-5x - 45) = -57
2x + 15x + 135 = -57
17x + 135 = -57
17x = -192
x = -11 5/17

Samuel is preventing a boulder from rolling down a hill with a slope of 35°. If the boulder
weighs 322 pounds, how much force is he exerting to hold the rock in place?
Answer:
1,809.98 lb*m/s^2
Step-by-step explanation:
First, we want to know how much weight of the boulder is projected along the path in which the boulder can move.
The weight of the boulder is:
W = 322lb*9.8 m/s^2 = (3,155.6 lb*m/s^2)
This weight has a direction that is vertical, pointing downwards.
Now, we know that the angle of the hill is 35°
The angle that makes the direction of the weight and this angle, is:
(90° - 35°)
(A rough sketch of this situation can be seen in the image below)
Then we need to project the weight over this direction, and that will be given by:
P = W*cos(90° - 35°) = (3,155.6 lb*m/s^2)*cos(55°) = 1,809.98 lb*m/s^2
This is the force that Samuel needs to exert on the boulder if he wants the boulder to not roll down.

please help me... anyone?
Step-by-step explanation:
a.) you have to substitute f(5) into the formula
f(x) = 3x^2 + 5
you do this by inserting five into your x :
f(x) = 3x^2 + 5
f(5) = 3(5^2) + 5
= 3(25) + 5
= 75 + 5
f(5) = 80
b.) to solve for g(5) ,, you do the exact same but with the formulae g(x) = 11x - 10
g(x) = 11x - 10
g(5) = 11(5) - 10
= 55 - 10
g(5) = 45
. we can see that f(5) is the greater quantity ,, furthermore it is greater by 35 . =
f(5) = 80 g(5) = 45
80 - 45
= 35

What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
The number of red squares = 15
The number of blue squares = 35
Now , the total number of squares is N = 50 squares
a)
The ratio of red squares to blue squares is = number of red squares / number of blue squares
The ratio of red squares to blue squares is = 15 / 35
The ratio of red squares to blue squares is = 3 : 7
b)
The ratio of blue squares to total squares is = number of blue squares / total number of squares
The ratio of blue squares to total squares is = 7 : 10
Hence , the proportion is solved

Write the recursive formula for the sequence
37, 67, 97, 127, 157
Answer:
The recursive formula for this arithmetic sequence would be [tex]a_{1} = 37[/tex], [tex]a_{i} = a_{i-1} + 30[/tex].
Step-by-step explanation:
A recursive formula is a formula that defines each term of a sequence using the preceding term(s). Recursive formulas must always state the initial term, or terms, of the sequence, as well as an equation defining [tex]a_{i}[/tex] in terms of preceding terms. Since the first term of this sequence is 37, that means [tex]a_{1} = 37[/tex]. The pattern in this arithmetic sequence between each term in ascending order would be 30 more than the previous term, so you can create the function [tex]a_{i} = a_{i-1} + 30[/tex]. So the recursive formula for this arithmetic sequence would be [tex]a_{1} = 37[/tex] and [tex]a_{i} = a_{i-1} + 30[/tex].

The required number of lines of symmetry the given figure holds is 2.
What is the line of symmetry?A line of symmetry is a line that divides a shape into two mirror images that are identical to each other. If a shape has a line of symmetry, it means that one-half of the shape is a reflection of the other half across the line of symmetry.
For example, a square has four lines of symmetry, because it can be divided into four identical mirror images. A rectangle has two lines of symmetry, one horizontal and one vertical because it can be divided into two identical mirror images.
Following the above example, in the given scenario, the figure has only 2 lines of symmetry.

1: True, 2: False
Step-by-step explanation:
With the first one, probability by defintion is the odds of if an event will happen or not, so it is true.
With the second one, it is false as if something is for sure going to happen, it will have a 100% or "1" chance of occurring. If it has a 1% chance of occuring, it would be 0.01.

For her birthday, Patty's parents gave her $5,000.00 which they put into a savings account that earns 10% interest compounded continuously. When Patty started college, she withdrew the entire balance of $5,789.00 and used it to pay for tuition. How long was the money in the account?
Answer:
1.465 years
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 10/100
r = 0.1 per year,
Then, to solve for time t, when compound interest is compounded continuously, the formula is given as:
t = ln(A/P) / r
Where
A = Amount after time t = $5,789.00
P = Principal = Initial amount = $5,00
r = 0.1
Hence,
t = ln(5,789.00/5,000.00) / 0.1
t = 1.465 years
Therefore, the money was in the account for 1.465 years

A life guard in a tower 20 ft above sea level spots a struggling surfer at an angle of depression of 15 . How far is the surfer from the base of the tower?
Answer: [tex]19.31\ ft[/tex]
Step-by-step explanation:
Given
The tower is at a height of [tex]h=20\ ft[/tex]
the angle of depression is [tex]15^{\circ}[/tex]
Suppose the surfer is x ft away from the base of the tower
[tex]\therefore \text{From the figure, we can write}\\\\\Rightarrow \cos 15^{\circ}=\dfrac{x}{h}\\\\\Rightarrow x=h\cos 15^{\circ}\\\Rightarrow x=20\cos 15^{\circ}\\\Rightarrow x=19.31\ ft[/tex]
Therefore, the surfer is at a distance of 19.31 ft from the base of the tower.
