find c and d. show your work.
9514 1404 393
Answer:
c = 6√2
d = 12
Step-by-step explanation:
The sides of any isosceles triangle (opposite the congruent angles) are congruent. Hence c = 6√2.
The hypotenuse of an isosceles right triangle is √2 times the side length, so ...
d = c√2 = (6√2)(√2) = 6·2
d = 12
__
If you don't believe that, you can always use the Pythagorean theorem to find d:
d^2 = (6√2)^2 +c^2
d^2 = 72 +72 . . . . . . . . . since c=6√2
d = √144
d = 12

red, khaki;
red, black;
red, white;
white, khaki;
white, black;
white, white;
black, khaki;

What single decimal multiplier would you use to increase by 5% followed by a 20% increase?
Answer:
The single decimal multiplier is 1.26.
Step-by-step explanation:
Multipliers:
For a decrease of a%, we multiply by: [tex]\frac{100-a}{100}[/tex]
For a increase of a%, we multiply by: [tex]\frac{100+a}{100}[/tex]
For consecutive changes, we multiply the multipliers.
Increase of 5%
Multiply by [tex]\frac{100+5}{100} = \frac{105}{100} = 1.05[/tex]
Increase of 20%
Multiply by [tex]\frac{100+20}{100} = \frac{120}{100} = 1.2[/tex]
Consecutive:
1.05*1.2 = 1.26
The single decimal multiplier is 1.26.
Answer: 1.26

Equation: w = 112 + 8t Which input results in an output of 176? What is the output in the ordered pair (4, 144)?
9514 1404 393
Answer:
8144Step-by-step explanation:
Generally, the single variable on the left side of the equation is the "output" or dependent variable, while any other variables on the right side of the equation are considered to be independent variables, or "input."
So, we assume your first question is asking for the value of t that makes w=176. Put the values in the equation and solve for the unknown.
w = 112 +8t
176 = 112 + 8t
64 = 8t . . . . . . . subtract 112
8 = t . . . . . . . . . divide by 8
The input for an output of 176 is 8.
__
Ordered pairs are always written as ...
(input, output)
So, (4, 144) means the output is 144 for an input of 4.

An electronics retailer is developing a model for insurance on new cell phone purchases. It estimates that 60% of customers never make a claim25% require a small repair costing an average of $50and 15% require a full refund costing $200. What is the average cost the retailer should expect to pay to each customer?
Answer:
$42.50
Step-by-step explanation:
$42.50 will cover the costs of all people who request full refunds, while still allowing the company to profit.
The average cost the retailer should expect to pay to each customer if It estimates that 60% of customers never make a claim is $4250.
What is average?The average is a numeric figure that represents a big amount of data in a single way. The average mark of the class is calculated by averaging the students' grades in a given subject.
It is more important to understand how the class as a whole performed than how each individual student performed.
Given:
It estimates that 60% of customers never make a claim, 25% require a small repair costing an average of $50 and 15% require a full refund costing $200,
Calculate the average cost as shown below,
Assume there are 100 customers, then,
The average cost = 25% of 100 × 50 + 15% of 100 × 200
The average cost = 25 × 50 + 15 × 200
The average cost = 1250 + 3000
The average cost = 4250
Thus, the average cost the retailer should expect to pay to each customer is $4250.

The number of country A forces in country B decreased to approximately 34,000 in 2014 from a high of about 100,000 in 2008. The amount of country A funding for country B security forces also decreased during this period. The function f (x) = -1.330x + 5.149x +5.517 can be used to estimate the amount of country A funding for country B security forces, in billions of dollars, x years after January 2007. In what year was the amount of country A funding for country B security forces about $ 10.5 billion?
Answer:
2009
Step-by-step explanation:
The question can be interpreted as:
[tex]f(x) = -1.330x^2 + 5.149x + 5.517[/tex]
Required
Determine x when f(x) = 10.5
Substitute 10.5 for f(x) in [tex]f(x) = -1.330x^2 + 5.149x + 5.517[/tex]
[tex]10.5 = -1.330x^2 + 5.149x + 5.517[/tex]
Collect Like Terms
[tex]-1.330x^2 + 5.149x + 5.517-10.5=0[/tex]
[tex]-1.330x^2 + 5.149x -4.983=0[/tex]
Using quadratic formula
[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a = -1.330[/tex]
[tex]b = 5.149[/tex]
[tex]c = -4.983[/tex]
[tex]x = \frac{-5.149 \± \sqrt{5.149^2 - 4*-1.330*-4.983}}{2*-1.330}[/tex]
[tex]x = \frac{-5.149 \± \sqrt{0.002641}}{-2.660}[/tex]
[tex]x = \frac{-5.149 \± 0.0514}{-2.660}[/tex]
Split:
[tex]x = \frac{-5.149 + 0.0514}{-2.660}\ or\ x = \frac{-5.149 - 0.0514}{-2.660}[/tex]
[tex]x = \frac{-5.0976}{-2.660}\ or\ x = \frac{-5.2004}{-2.660}[/tex]
[tex]x = 1.92\ or\ x = 1.96[/tex]
Both values of x approximates to 2.
So:
[tex]x = 2[/tex]
2 years after 2007 is 2009.
Hence, the funding is about $10.5 billion in 2009

Answer: 398765
=====================================================
Work Shown:
x = total number of copies sold so far
8.1% of x = 0.081*x = amount of copies sold in the first month
0.081*x = 32300
x = 32300/0.081
x = 398,765.432098766
x = 398,765
Rounding to the nearest whole number, about 398,765 copies have been sold so far to date.
Calculate the value of x
Answer:
Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

Elena needs 1/4 meter of ribbon to decorate the border of a photo frame.
Enter the number of photo frames that can be decorated using 3/4 meter of ribbon.
Answer:
3 photo frames
Step-by-step explanation:
1 frame uses 1/4 meters. You can solve this as a proportion. 1 is to 1/4 and x is to 3/4. 1/4 x 3 is 3/4. So multiply 3 x 1 as well. You get 3.

The arcs on the Golden Gate Bridge.
I think about the Golden Gate Bridge, which is a suspension bridge.
As in any suspension bridge, a long cable is supported by two large supports.
The cable falls from support, in the form of a curve concave upwards, to a minimum point that is the vertex of the parabola, through which the axis of symmetry passes, and curves again upwards to ascend to the upper end of the other support.
As a unique feature of this parabolic arc, you can tell that the concavity is upward; the parabola opens upward.
Also, you can tell that the parabola is vertical, which means that the axis of symmetry is vertical.
The symmetry is clear because the curve to the left of the vertex is a mirror image of the curve to the right of the vertex. Hope I helped, have a good day!
I have to find the domains of these functions and write the answer in interval notation.
Answer: 2,5
Step-by-step explanation:
In order to find the domain of a function, check the function for two conditions:
a zero in a denominator
a negative under an even root
Exclude the values at which the function satisfies either or both of these conditions from its domain.
G(x) has no root but it does have a denominator. Therefore, check the first condition by setting the denominator equal to zero and excluding those solutions from the domain.
