Answer:
61 degrees.
Step-by-step explanation:
Use the law of cosine.
In this case, the law of cosine is:
7^2=4^2+8^2-2(4)(8)cos a
Meaning:
7^2-4^2-8^2/-2(4)(8)=.434
Then do the inverse cosine of .434, and it will equal to 61.02
Round to the nearest tenth and you'll get A= 61 degrees.
Answer: 61 degrees
Step-by-step explanation:
7^2=4^2+8^2-2(4)(8)cos a
7^2-4^2-8^2/-2(4)(8)=.434
Then do the inverse cosine of .434, and it will equal to 61.02
Round to the nearest tenth and you'll get A= 61 degrees.

Complete the square to write each equation in vertex form. Then, state whether the vertex is a minimum or a maximum and give its coordinates.
Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
• If a > 0 then vertex is a minimum
• If a < 0 then vertex is a maximum
Given
y x² - 8x + 14
(a)
To complete the square
add/ subtract ( half the coefficient of the x- term)² to x² - 8x
y = x² + 2(- 4)x + 16 - 16 + 14
y = (x - 4)² - 2 ← in vertex form
(b)
Since the multiplier a = 1 > 0 then vertex is a minimum
(c)
(h , k ) = (4, - 2 ) ← coordinates of vertex

Oliver wants to buy a hat that has an original price of $25 . The store is having a 20% off sale on everything in the store. Question: With this discount, what is the final cost of the hat?
Answer:
$20
Step-by-step explanation:
There are a few ways to do this. We know 20% is 1/5 and 1/5 is 5 dollars. since that's the percent off, we would subtract it from 25.
For general percents off, they might not be so easy. It is important to know the method. We must multiply by the decimal of the percent, so
[tex]25 \times .20 = 5[/tex]
Now, since it is this amount off, we subtract 5 from 25.
[tex]25 - 5 = 20[/tex]
$20 is the final price of the hat!

What is the value of x in3 √ x 9?
In the given equation x = 9 is the value that satisfies the equation.
What are Square root?The square root of a number is a value that, when multiplied by itself, equals the original number. For example, the square root of 9 is 3, because [tex]3*3 = 9[/tex]. The symbol for square root is "√" and it can also be represented as "sqrt".
In the given equation [tex]x = 9[/tex] is the value that satisfies the equation.
To find the value of x in the equation [tex]3 \sqrt{x} = 9[/tex], we first need to square both sides of the equation to eliminate the square root.
[tex]3 \sqrt{x} = 9[/tex]
Squaring both sides:
[tex](3 \sqrt{x} )^2 = 9^2[/tex]
[tex]x = 9^2 / 3^2 = 9^2 / 9 = 9[/tex]
Therefore, x = 9 is the value that satisfies the equation.

Simplify (s^-5)^3. Write your answer using only positive exponents.
The given expression (s⁻⁵)³ is equivalent to (1/s)¹⁵.
What is exponent?Exponent is a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression. Mathematically -
[tex]$b^x = \underbrace{b \times \dots \times b}_{x \text{ times}}[/tex]
where -
[b] = base of the logarithm
[x] = exponent
Given is the expression as follows -
(s⁻⁵)³
We can write the expression as -
(s⁻⁵)³ = (1/s⁵)³ = (1/s¹⁵) = (1/s)¹⁵
Therefore, the given expression (s⁻⁵)³ is equivalent to (1/s)¹⁵.

which is the correct comparison of solutions for 2(5-x) > 6 and 22 > 2(9+x)?
The correct comparison of solutions for the expression is x < 2
How to determine the correct comparison of solutions for the expressionFrom the question, we have the following parameters that can be used in our computation:
2(5-x) > 6 and 22 > 2(9+x)
Rewrite the expression properly
So, we have the following representation
2(5 - x) > 6 and 22 > 2(9 + x)
Divide both sides of the expressions by 2
So, we have the following representation
5 - x > 2 and 11 > 9 + x
Subtract both sides of the expression by the constant term
This gives
-x > -3 and 2 > x
Rewrite as
x < 3 and 2 > x
So, we have
x < 3 and x < 2
When combined, we have
x < 2
Hence, the solution is x < 2

The quadrilateral's image points will be,A(3, 3) → A'(-3, 3) R(5, 7) → R'(-7, 5) M(7, 5) → M'(-5, 7) Y(5, 1) → Y'(-1, 5).
If a point (x, y) is rotated 180 degrees anticlockwise with respect to the origin, the rotational rule is:
(x, y) → (-y, x) (-y, x)
Consequently, the image point's coordinates following rotation will be (-y, x).
Using this guideline,
The quadrilateral's image points will be,
A(3, 3) → A'(-3, 3)
R(5, 7) → R'(-7, 5)

you are building a 3-foot tall chest. you want the volume to be 60 cubic feet. what should the area of the base be
Answer:
You want the area of the base to equal 20 ft^2
Step-by-step explanation:
Volume of a cube= (L)(w)(h)
Area of base = (L)(W)
60 cubic feet is the volume we are trying to acheive. Since the volume for a cube is (L)(w)(h), 3 needs to multiply by the area of the base to equal the volume. since 3 times 20 equals 60(You solve this by dividing 60 by 3) the base needs to equal 20ft^2.

Which is not a property of a parallelogram?
A) All sides are congruent. B) Diagonals are perpendicular bisectors of each other. C) Opposite angles are congruent. D) Diagonals are congruent.
A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. All angles are congruent, and the diagonals bisect each other and are congruent. It does not, however, have the property that all angles are equal.
A parallelogram is a four-sided shape with two pairs of parallel lines. The opposite sides of the parallelogram must be congruent, meaning that they have the same length. All angles are congruent, which means that they all have the same measure. The diagonals of the parallelogram bisect each other, meaning that they divide each other into two equal parts, and they must also be congruent. All of these properties are true for a parallelogram, except that the angles do not have to be equal. The angles can be either acute, obtuse, or right angles, but they must all have the same measure. So, in conclusion, the property that is not true for a parallelogram is that all angles are equal.
