This is a right triangle. Use the Pythagorean theorem to solve:
x^2 + 5.8^2 = 15.6^2
x^2 + 33.64 = 243.36
Subtract 33.64 from both sides:
x^2 = 209.72
Take the square root of both sides:
x = 14.48171
Round to 1 decimal place:
x = 14.5 in.
Answer:
x = 14.5 in
Step-by-step explanation:
There is something called pythagoras' theorem. It states that
a^2 + b^2 = c^2,
a, b and c being sides of a right-angled triangle.
C is always the hypotenuse and a and b are any of the other two.
(The hypotenuse is always the longest side, and always opposite to the right angle, which is always the biggest angle of a right-angled triangle.)
So here we know two sides, the hypotenuse and another side. Let's substitute them into the formula:
5.8^2 + x^2 = 15.6^2
x^2 = 15.6^2 - 5.8^2
x^2 = 243.36 - 33.64
x^2 = 209.72
x = sqr209.72
x = 7sqr107/5 = 14.48171261 in
= 14.5 in (if rounded to 3 significant figures)
You could use a shortcut to do all this and find the answer more quickly:
a^2 = c^2 - b^2 or b^2 = c^2 - a^2
also:
a = sqr(c^2 - b^2)
x = Sqr(15.6^2 - 5.8^2)
= 14.5 in

help would be greatly appreciated:)
Answers
Answer:
I have no idea
Step-by-step explanation:
Defining terms
Y is any y value on the the line
X is any x value in the line
M is the slope
B is the y intercept (0,b)
The problem is essentially asking you to find the value for b
To do this, we sub in the values we know
So, put the slope value in the formula
Y=(-1/4)x+b
From there, you can substitute the coordinate values provided and solve for b
-5=(-1/4)(-5)+b
-5=(5/4)+b
-6.25=b
So now we can rewrite the whole equation as
Y=(-1/4)x-6.25

Manolo says that the solution of the equation g squared equals 36 is g = 6 because 6*6 = 36. Is Manolos reasoning complete? Explain.
Answers
Answer: No. Manolo forgot to include that the opposite of squaring a number is square rooting. If you take the square root of 36, you get 6. When you square a number, you multiply it by itself, which is what Manolo did. He multiplied 6 by itself and got the answer of 36.
Step-by-step explanation: Hope this helps!
The Manolos reasoning is not complete because the quadratic equation has two roots and the roots are 6 and -6.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
It is given that:
A quadratic equation:
g² = 36
Manolo says that the solution of the equation g squared equals 36 is g = 6 because 6×6 = 36
As we know, the quadratic equation has two roots.
To solve the quadratic equation we can use the identity:
a² - b² = (a + b)(a - b)
g² = 36
g² - 36 = 0
g² - 6² = 0
(g + 6)(g - 6) = 0
g + 6 = 0 ⇒ g = -6
g - 6 = 0 ⇒ g = 6
Thus, the Manolos reasoning is not complete because the quadratic equation has two roots and the roots are 6 and -6.

Suppose you want to find the 40th term of a sequence. Would you rather use a recursive rule or an explicit rule? Explain your reasoning.
Answers
Answer:
I'd rather use an explicit rule for bigger values of n
Step-by-step explanation:
Suppose we have a sequence like:
6,14,22,30,..
And we wanted to calculate the 200th term. The recursive rule is:
[tex]a_n=a_{n-1}+8[/tex]
Since each term is 8 more than the previous term. If we wanted to caclulate the term n=200, we would need to go up to 200 one-by-one until reaching the desired value.
The explicit rule is:
[tex]a_n=6+8(n-1)[/tex]
To find the term for n=200, just substitute into the rule:
[tex]a_{200}=6+8(200-1)=1598[/tex]
Thus, I'd rather use an explicit rule for bigger values of n

Study the diagram of circle K, where JL and LM are tangent to circle K at points J and M, respectively. Also, JL=3x+10 and ML=7x−6.
What is the length of LM?
17.6

22
Answers
Answer:
LM = 22
Step-by-step explanation:
Tangents to a circle from an external point to the circle are congruent , that is
ML = JL , substitute values
7x - 6 = 3x + 10 ( subtract 3x from both sides )
4x - 6 = 10 ( add 6 to both sides )
4x = 16 ( divide both sides by 4 )
x = 4
Then
LM = 7x - 6 = 7(4) - 6 = 28 - 6 = 22

A woman wishes to enclose a rectangular garden with fencing, using the side of her garage as one side of the rectangle. A neighbor gave her 27 feet of fencing, and she wants the length of the garden along the garage to be 6 feet more than the width. What are the dimensions of the garden?

Answer:
Width = 3.75 feet
Length = 9.75 feet
Step-by-step explanation:
Given:
Length of fencing = 27 feet
Find:
Dimensions of the garden
Computation:
Assume
Width = x
So,
Length = x + 6
2(L+B) = Perimeter
2(x + x + 6) = 27
2(2x + 6) = 27
4x + 12 = 27
4x = 15
x = 3.75
Width = 3.75 feet
Length = 3.75 + 6 = 9.75 feet

Kim and her mom have some items to donate to families in need for Christmas baskets. They have 100 rolls and 25 pumpkin pies. They want every basket to be exactly the same, and they don't want any leftover food. What is the largest number of baskets that they can make?
Answers
Answer:
There will be 25 baskets each container 4 rolls and 1 pumpkin
Step-by-step explanation:
Rolls = 100
Pumpkins = 25
To make every basket to be exactly the same number of rolls and pumpkins,
Find the highest common factor of 100 and 25
100 = 1, 2, 4, 5, 10, 25, 50, 100
25 = 1, 5, 25
The highest common factor of 100 and 25 is 25
Rolls = 100
= 100/25
= 4
Pumpkins = 25
= 25/25
= 1
Therefore,
There will be 25 baskets each container 4 rolls and 1 pumpkin

perpendicular bisector: OP

Explanation:
perpendicular lines are lines that intersect at a right (90 degrees) angle.
so I drew the line segment AB with CD intersecting at point X at 4 cm from point A, OP intersecting at point Z at 5 cm, and LM intersecting at point Y at 7 cm.
perpendicular bisector is a line or a segment perpendicular to a segment that passes through the midpoint of the segment.
the midpoint of line AB is at 5 cm because the total length is 10 cm (it’s just the middle)

Step-by-step explanation:
5n-3(4n+1) =
5n -12n -3= 0
-7n - 3
Answer: -7n-3
Step-by-step explanation: first bring the 5n down then multiply -3x4n gives you -12 and multiply 5x1 that gives you 5 so you would write (5n−12n)−3
then remove the parentheses combine like terms like 5 and 12 are alike because of the n's that means subtract because of the - sign 5-12 which gives you -7 and then you bring down -3 because it's outside the parentheses and that's the answer.
