Answer:
A = 50 square units
Step-by-step explanation:
Right Triangles
A right triangle is identified because it has one internal angle of 90°.
The longest side is called hypotenuse and the other two sides are called legs. Being c the hypotenuse and a and b the legs, the Pythagora's theorem relates the with the equation:
[tex]c^2=a^2+b^2[/tex]
If the triangle is also isosceles, then both legs have the same measure or a=b:
[tex]c^2=a^2+a^2=2a^2[/tex]
Since we know the hypotenuse has a measure of 10\sqrt{2}:
[tex](10\sqrt{2})^2=2a^2[/tex]
Operating:
[tex]100*2=2a^2[/tex]
Dividing by 2:
[tex]a^2=100~~\Rightarrow a=\sqrt{100}[/tex]
a = 10 units
The area of the triangle is:
[tex]\displaystyle A=\frac{a.b}{2}[/tex]
[tex]\displaystyle A=\frac{10*10}{2}[/tex]
A = 50 square units

Find 3 consecutive integers such that the sum of all 3 integers is equal to 4 times the smallest integer minus 9. Please help I need it asap I will appreciate it a lotttt
Answer:
The three integers are 12,13 and 14
Step-by-step explanation:
Let
x,x+1,x+2 be three consecutive integers.
Out of these, the smallest one is x and largest is x+2 as it comes at last in the integers.
So according to given statement
[tex]x+(x+1)+(x+2) = 4x-9[/tex]
This is a linear equation in one variable, which can simply be solved by using equality properties
[tex]x+x+1+x+2 = 4x-9\\3x+3 = 4x-9[/tex]
Subtracting 4x from both sides
[tex]3x+3-4x = 4x-9-4x\\-x+3=-9[/tex]
Subtracting 3 from both sides
[tex]-x+3-3 = -9-3\\-x = -12\\x = 12[/tex]
The smallest integer is 12.
The other integers are:
x+1 = 12+1 = 13
x+2 = 12+2 = 14
Hence,
The three integers are 12,13 and 14

A student has a range of values from 0.000001 to 1,000,000, but limited paper to graph these values on. How might the student be able to graph these results clearly?
Answer:
logarithmic scale
The student might be able to graph these results clearly by taking the log of the values.
What is logarithm of a number?"Logarithms are the inverse of exponents. ""x is the logarithm of n to the base b if [tex]b^x=n[/tex]"For given question,
A student has a range of values from 0.000001 to 1,000,000
We need to find the way so that the student will be able to graph these results.
We can write 0.000001 as [tex]1\times 10^{-6}[/tex]
[tex]\Rightarrow 0.000001=10^{-6}[/tex]
and 1,000,000 as [tex]1\times 10^6[/tex]
[tex]\Rightarrow 1,000,000=10^6[/tex]
If we take the log of these range values, then it would be,
[tex]\Rightarrow log(10^{-6})=-6[/tex]
and [tex]log(10^6)=6[/tex]
This means, the student might be able to graph these results clearly by taking the log of the values.

The parabola of a given quadratic function opens up. What is true about the vertex of that function?
The vertex is the maximum.
The vertex is unaffected.
There is no vertex.
The vertex is the minimum.
Answer:
D
Step-by-step explanation:
The vertex is a point where the slope is 0 so opening up the vertex is the minimum so option (D) will be correct.
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
The graph is easy to understand behavior of the graph.
For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.
Vertex is a point where the rate of change or slope of the function is zero.
Since if the slope is zero it means the tangent at that point will be horizontal.
If the parabola opens up then the point where it is changing its direction will be vertex as shown below.
So vertex has a minimum value of y.
Hence "The vertex is a point where the slope is 0 so opening up the vertex is the minimum so option (D) will be correct".

Write the slope-intercept form of the equation of the line described. through (2, -5) perpendicular to y = 1/3x -1
Answer:
y = -3x + 1
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes, so the slope will be -3.
Plug in the slope and given point into y = mx + b
y = mx + b
-5 = -3(2) + b
-5 = -6 + b
1 = b
Then, plug in the slope and y intercept into y = mx + b again:
y = -3x + 1 will be the equation of the line
find the slope and the y-intercept of 7x = 2y-4
Answer:
Slope: [tex]\frac{7}{2}[/tex]
Y-intercept: (0, 2)
Step-by-step explanation:
7x = 2y - 4
-2y = -7x - 4
y = [tex]\frac{-7}{-2}[/tex] x - [tex]\frac{4}{-2}[/tex]
y = [tex]\frac{7}{2}[/tex] x + 2
The slope is always the coefficient of x and the y-intercept is always the constant. It looks like (0, constant) when written in y-int form.
Answer:
slope (m) is 7/2 (aka 3.5) and y-int is (0,2)
Step-by-step explanation:
I don't really have an explanation, basically rearrange the problem so that to y is on the left but it would be 2y so divide the right side by two. I an explain further in depth if needed

Aidan has been offered a job to paint the outside of a barn. If one gallon costs $35 and covers 550 square feet. How much will it cost to paint the barn with one coat?
Complete Question
The diagram of the barn is shown on the first uploaded image
Answer:
The cost is [tex]C = \$ 530[/tex]
Step-by-step explanation:
From the question we are told that
The cost of one gallon of paint is [tex]c = \$35[/tex]
The area the one gallon of paint covers is [tex]A = 550 \ square\ feet[/tex]
Generally from the diagram the region of the barn which can be painted is mathematically represented as
[tex]A =80 * 35 + 38 * 35 + 2( \frac{1}{2} * 38 * 2 )[/tex]
=> [tex]A = 8336 \ ft^2[/tex]
From the question
1 gallon covers 500 square feet
x gallon will cover 8336 square feet
So
[tex]x = \frac{8336}{550}[/tex]
=> [tex]x =15 \ gallons[/tex]
Generally the cost of 15 gallons of paint is mathematically represented as
[tex]C = c * x[/tex]
=> [tex]C = 15 * 35[/tex]
=> [tex]C = \$ 530[/tex]
