Answer:

Area of the shape is 21 m².

Step-by-step explanation:

From the given figure it is clear that the figure contains one square with edge 3 m and 4 congruent triangles with base 3 m and height 2 m.

The area of a square is

[tex]A=a^2[/tex]

[tex]A_1=(3)^2=9[/tex]

The area of square is 9 m².

The area of a triangle is

[tex]A=\frac{1}{2}\times base \times height[/tex]

The area of a triangle whose base is 3 m and height 2 m is

[tex]A=\frac{1}{2}\times 3 \times 2=3[/tex]

The area of a triangle is 3 m². So, the area of 4 triangles is

[tex]A_2=4 \times A=4\times 3=12[/tex]

The area of 4 triangles is 12 m².

The area of shape is

[tex]A=A_1+A_2=9+12=21[/tex]

Therefore the area of the shape is 21 m².

Something that a right triangle is characterised by is the fact that we may use Pythagoras' theorem to find the length of any one of its sides, given that we know the length of the other two sides. Here, we know the length of the hypotenuse and one other side, therefor we can easily use the theorem to solve for the remaining side.

Now, Pythagoras' Theorem is defined as follows:

c^2 = a^2 + b^2, where c is the length of the hypotenuse and a and b are the lengths of the other two sides.

Given that we know that c = 24 and a = 8, we can find b by substituting c and a into the formula we defined above:

c^2 = a^2 + b^2

24^2 = 8^2 + b^2 (Substitute c = 24 and a = 8)

b^2 = 24^2 - 8^2 (Subtract 8^2 from both sides)

b = √(24^2 - 8^2) (Take the square root of both sides)

b = √512 (Evaluate 24^2 - 8^2)

b = 16√2 (Simplify √512)

= 22.627 (to three decimal places)

I wasn't sure about whether by 'approximate length' you meant for the length to be rounded to a certain number of decimal places or whether you were meant to do more of an estimate based on your knowledge of surds and powers. If you need any more clarification however don't hesitate to comment below.

Answer:

Answer:

$504

Step-by-step explanation:

since there is 12 months in a year , the family would pay 12$ a year.

12x12= 144

then since they paid a down payment of $360

360+144=504

so they would have paid $504

Answer:

After factorization of given expression we get 12( x + 30 ).

Step-by-step explanation:

Given:

Money Saved by Nolansky family for down payment = $ 360

x is the monthly payment for 1-year

Expression Representing the total cost of the computer = 12x + 360

To find: Factors of the given expression.

We need to factor the given expression. We do it by taking the common factor of both the term.

Consider,

12x + 360

= 2 × 2 × 3 × x +  2 × 2 × 2 × 3 × 3 × 5

= 2 × 2 × 3 × ( x + 2 × 3 × 5 )

= 12 × ( x + 30 )

= 12 ( x + 30 )

Therefore, After factorization of given expression we get 12( x + 30 ).

Answer:

x = [tex]3\frac{1}{3}[/tex]

Step-by-step explanation:

We are given the following expression which we are to solve for x and give the answer in a mixed form of fraction:

[tex] \frac { 3 x } { 2 } = 5 [/tex]

Taking the denominator to the other side of the equation and multiplying it to get:

[tex]3x=10[/tex]

[tex] x = \frac { 1 0 } { 3 } [/tex]

Writing it in mixed number:

[tex] x = 3 \frac { 1 } { 3 } [/tex]

Final answer:

To solve the equation 3x/2 = 5, first multiply both sides by 2 and then divide by 3, resulting in x = 10/3, which is 3 1/3 as a mixed number.

Explanation:

To solve the equation given, 3x/2 = 5, one must isolate the variable x. This can be done by multiplying both sides by the denominator to cancel it out, followed by dividing by the coefficient of x. Here's the step-by-step calculation:

Multiply both sides by 2 to get rid of the fraction: 2 * (3x/2) = 2 * 5, which simplifies to 3x = 10.

Divide both sides by 3 to solve for x: 3x / 3 = 10 / 3, which simplifies to x = 10 / 3.

Express 10/3 as a mixed number: 10/3 is 3 1/3 because 3 goes into 10 three times with a remainder of 1.

This gives us the final answer in terms of a mixed number.

Step-by-step explanation:

It is important to remember that when we graph a linear equation, we get a line and when we graph a quadratic equation, we get a parabola.

Then,  given a system of a quadratic equation and a linear equation, there are three possibles cases for the solution:

- If the line and the parabola never intersect, then there is no real solution.

- If the line just touches the parabola, then there is one real solution.

- If the line and the parabola intersect at two points, then there Two real solutions.

Then the system of a quadratic equation and a linear equation may have: no intersections points, one intersection point or two intersection points.

Answer: Second Option

[tex]g(x) = 2x^2 + 1[/tex]

Step-by-step explanation:

By definition, a function f(x) is an even function if:

[tex]f (-x) = f (x)[/tex]

This means that each input value x and its negative -x are assigned the same output value y.

To verify which of the functions is even, you must test [tex]f(-x) = f(x)[/tex] for each of them

First option

[tex]g(x) = (x - 1)^2 + 1[/tex]

[tex]g(-x) = (-x -1)^2 +1\\\\g(-x) = ((-1)(x+1))^2 +1\\\\g(-x) = (-1)^2(x+1)^2 +1\\\\g(-x) = (x+1)^2 +1\neq g(x)[/tex]

Second option

[tex]g(x) = 2x^2 + 1[/tex]

[tex]g(-x) = 2(-x)^2 + 1[/tex]

[tex]g(-x) = 2x^2 + 1=g(x)[/tex]

Third option

[tex]g(x) = 4x + 2[/tex]

[tex]g(-x) = 4(-x) + 2[/tex]

[tex]g(-x) = -4x + 2\neq g(x)[/tex]

Fourth option

[tex]g(x) = 2^x[/tex]

[tex]g(-x) = 2^(-x)[/tex]

[tex]g(-x) = \frac{1}{2^x}\neq g(x)[/tex]

Answer:

One solution.

Step-by-step explanation:

To determine the number of possible solutions for a triangle with A = 113° , a = 15, and b = 8, we're going to use the law of sines which states that: "When we divide side a by the sine of angle A  it is equal to side b divided by the sine of angle B,  and also equal to side c divided by the sine of angle C".

Using the law of sines we have:

[tex]\frac{sin(A)}{a} = \frac{sin(B)}{b}[/tex]

[tex]\frac{sin(113)}{15} = \frac{sin(B)}{8}[/tex]

Solving for B, we have:

[tex]sin(B)=0.4909[/tex]

∠B = 29.4°

Therefore, the measure of the third angle is: ∠C = 37.6°

There is another angle whose sine is 0.4909 which is 180° - 29.4° = 150.6 degrees. Given that the sum of all three angles of any triangle must be equal to 180 deg, we can't have a triangle with angle B=113° and C=150.6°, because B+C>180.

Therefore, there is one triangle that satisfies the conditions.

Answer: [tex]r>-1[/tex]

Step-by-step explanation:

Given the inequality provided [tex]17r > -17[/tex], you need to solve for "r".

To do this, you can divide both sides of the inequality by 17. Then you  get the following solution:

[tex]17r > -17\\\\\frac{17r}{17}>\frac{-17}{17}\\\\(1)r>(-1)\\\\r>-1[/tex]

Now, you can expressed this solution in Interval notation form.

 Therefore, the solution of the inequality in Interval notation is:

The distance between the given coordinate points is √13 units.

The given coordinate points are (7/3,2) and (1/3,-1).

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x1, y1) and (x2, y2) is Distance = √[(x2-x1)²+(y2-y1)²].

Substitute (x1, y1)=(7/3,2) and (x2, y2)=(1/3,-1) in distance formula, we get

Distance = √[(1/3-7/3)²+(-1-2)²]

= √[(-2)²+(-3)²]

= √13 units

Therefore, the distance between the given coordinate points is √13 units.

Answer:

Second option.

Step-by-step explanation:

The angle [tex](3x+17)\°[/tex] and the angle [tex](4x-8)\°[/tex] are alternate exterior angles, then they are congruent. So we can can find "x":

[tex]3x+17=4x-8\\17+8=4x-3x\\x=25[/tex]

Then, the angle  [tex](4x-8)\°[/tex] is:

 [tex](4x-8)\°=(4(25)-8)\°=92\°[/tex]

You can observe that the angle identified in the figure attached as "3" and the angle 46° are Alternate interior angles, then they are congruent.

Since the sum of the measures of the angles that measure 92°, 46° and the angle "2" is 180°, we can find the measure of the angle "2" by solving this expression:

[tex]92\°+46\°+\angle 2=180\°\\\\\angle 2=180\°-92\°-46\°\\\\\angle 2=42\°[/tex]

Answer:I agree that 46 is correct

Answer:

The possible value of 'x' is: 3.

Step-by-step explanation:

A polynomial has no real solutions when the discriminat is less than zero. Given the following polynomial: [tex]ax^{2} +bx+c = 0[/tex] the discriminant is given by: [tex]Discriminant = b^{2}-4ac[/tex]

In this case, a=1, b=2. By substituting those values:

[tex]Discriminant = 2^{2}-4(1)c[/tex] ⇒ [tex]Discriminant = 4-4c[/tex]

Given that the discriminant should be less tha zero, then 'c' must be greater than one.

In this case, the only possible value of 'x' is: 3.

Answer:

3

Step-by-step explanation:

Given

x² + 2x + c = 0 ← in standard form

with a = 1, b = 2 and c = c

If there are no real solutions then the discriminant

b² - 4ac < 0, that is

2² - (4 × 1 × c ) < 0

4 - 4c < 0 ( subtract 4 from both sides )

- 4c < - 4

Divide both sides by - 4, reversing the sign as a consequence

c > 1

Hence a possible value of c is 3

The answer is:

The equation of the line with slope 3 that passes through the point M(1,2) is:

[tex]y=3x-1[/tex]

To determine the equation of the line with slope equal to 3, that passes through the point M(1,2) we can use the following equation:

The slope-intercept of the line is defined by the following equation:

[tex]y=mx+b[/tex]

Where,

m is the slope of the line

b is the constant number which represents the y-axis intercept of the line.

So, using the given information, we have:

[tex]y=3x+b[/tex]

Then, using the given point to calculate "b", we have:

[tex]2=3*1+b[/tex]

[tex]2=3+b[/tex]

[tex]2-3=b[/tex]

[tex]b=-1[/tex]

So, rewriting the equation, we have:

[tex]y=3x-1[/tex]

Hence, the equation of the line with slope 3 that passes through the point M(1,2) is:

[tex]y=3x-1[/tex]

The piecewise function can be graphed by graphing the two sub-functions, x+3 and 2x, separately for their defined ranges of x-values, with x+3 for 4 < x < 8 and 2x for x > 8, and combining them to form the complete graph of the piecewise function.

To graph this piecewise function, you would start by separately graphing each sub-function, x+3 and 2x, within their defined ranges of x-values, with x+3 defined for 4 < x < 8 and 2x defined for x > 8.

For 4 < x < 8, plot the line y = x + 3, but only include the section of the line where x values are greater than 4 and less than 8. Keep in mind this will not include the points where x=4 or x=8.

Next, for x > 8, plot the line y = 2x, but this time only include the section of the line where x values are greater than 8. Ensure X=8 is excluded.

The two separate lines drawn are the graphical representation of the piecewise function f(x).
