Answer:
a ( copper and nickel
b ( 1034.9
Step-by-step explanation:
Add all the values of melting points
2,651 + -37.89 = 2613.11
2613 + -458 = 2155.11
2155.11 + 1984.32 = 4139.43
Divide the number by the number of numbers: 4139.43/4 = 1034.8575
1034.8575 rounded to the nearest tenth is 1034.9, thats how you find the mean, or the average.
Edward deposited $9,000 into a savings account 2 years ago. The simple interest rate is 4% How
much money did Edward earn in interest?
Substitute the values into the equation.
Interest=$ 3.0. years
Please help
Answer:
$734.40
Step-by-step explanation:
y=9,000(1.04)^t is our equation for this.
The 9,000 is the starting amount.
1.04 is the 4% since 4% is 4/100 which equals 0.04, then we add 1 to that since it's increasing in value.
y represents our output.
t represents time (in years for this equation)
Since they give us the amount of years since he deposited the $9,000, we put the number they gave us (2 years) into the equation, replacing t.
y=9,000(1.04)^2
Put the right side into a calculator and it gives you 9734.4.
That's the total amount he has now, so to find how much he earned we subtract the starting amount (9000).
734.4.
Edward earned $734.40.

Find the equations of the normals to the curve xy = 3 which are parallel to the
line 3x - y - 2 = 0.
Answer:
y = 3x + 8.
y = 3x - 8
Step-by-step explanation:
The slope of the tangent to the curve at a given point is obtained from the derivative.
xy = 3
y = 3/x
y = 3 x^-1
y' = -3x^-2
The slope of the normal (which is perpendicular to the tangent)
= -1 / -3x^-2 = 1/3 x^2.
Consider the given line:
3x - y - 2 = 0
y = 3x - 2 , so the slope of this line = 3.
Now this line is parallel to the normal so 1/3 x^2 = 3
Therefore x^2 = 9 and x = -3, 3.
Find the equations of the normals:
At x = -3, y = 3/-3 = -1, which gives the equation:
y - (-1) = 3(x - -3)
y = 3x + 8.
At x = 3 , y = 1
y - 1 = 3(x - 3)
y = 3x - 8.
What type of triangle has an exterior angle that is obtuse at two vertices? Explain your reasoning.
Answer:
A right triangle
Step-by-step explanation:
A right triangle would meet these characteristics. A triangle's inner angles always add up to be 180 degrees. A right triangle has one angle at 90 degrees meaning the other two angles need to be less than 90 degrees and sum up to be 90 degrees. This would indicate that both of these angles' exterior angles would be obtuse because they would be wider than 90 degrees.
it's not 30 that's not an answer also i need help figuring it out please

2 Name a point that is in the solution set of the quadratic inequality shown
below.
Answer:
Point (3, 2) is in the solution set of the quadratic inequality
Step-by-step explanation:
If the sign of the inequality is > OR <, then the line represents the inequality is a dashed line and all the points on the line do not belong to the solution set of the inequality If the sign of the inequality is ≥ OR ≤, then the line represents the inequality is a solid line and all the points on the line belong to the solution set of the inequalityFrom the given figure
∵ The line the inequality is a solid line
∴ The solution set of inequality have all the points on the line and
the points on the shaded area
→ We can choose any point on the line or on the red area
∵ Point (3, 2) is the vertex of the parabola
∴ Point (3, 2) is in the solution set of the quadratic inequality

On a coordinate plane, a rectangle and a right triangle are shown. The rectangle has points (0, 4), (4, 10), (7, 8), and (3, 2). The triangle has points (5, 2), (7, 5), and (7, 2). Each unit on the coordinate grid represents 1 yard. The rectangular pool and triangular hot tub shown are both in need of covers. How much total material is needed to cover both?
Answer:
the answer is 29 square yards. took the test got it right
Step-by-step explanation:
The total material needed to cover both is 29 square yards.
What is a triangle?A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.
Vertices of rectangular pool are (0, 4), (4, 10), (7, 8), and (3, 2).
[tex]AB=\sqrt{(7-3)^{2}+(8-2)^{2}}\\\\= \sqrt{16+36}\\\\=\sqrt{52} =CD[/tex]
[tex]BC=\sqrt{(7-4)^{2}+(8-10)^{2}}\\=\sqrt{9+4}\\\\=\sqrt{13} =DA[/tex]
To find the area of rectangular pool
=Length × Breadth
=√52 ×√13=13×2
=26 sq. yard
Vertices of triangle given are P(5,2),Q(7,2) and R(7,5).
PQ= 2 units, QR= 3 units
Area of right triangle PQR = 1/2 ×PQ×PR
Area =1/2×2×3= 3 sq. yards
To find total material needed to cover( that includes bot rectangular pool and triangular hot tub)
= Area of rectangle + Area of right triangle
=26+3=29 square yards

if E(3,6), F(1,0), G(-1,3) translated along the vector <-3,-2> what would be the new plots
Answer: need the options you choos frome
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
The translation < - 3, - 2 >
Means subtract 3 ( a shift left ) from the x- coordinate and subtract -2 ( a shift down ) from the y- coordinate.
E(3, 6 ) → E'(3 - 3, 6 - 2 ) → E'(0, 4 )
F(1, 0 ) → F'(1 - 3, 0 - 2 ) → F'(- 2, - 2 )
G(- 1, 3 ) → G'(- 1 - 3, 3 - 2 ) → G'(- 4, 1 )
