Ahmed wants to make a triangle. He has rods that measure 9 inches and 15 inches. The rods cannot be cut. Which is the length of a rod he could use to complete the triangle?

what is the answer?

6.72 liters per 100km

35 miles per gallon is 6.7204 liters per 100 kilometers

Here given ,

1 mile = 1.609km

1 gallon = 4.546 liters

We have to find 35 MPG to L/100km,

35 miles per gallon = 6.7204 liters per 100km

6.7204 to 3 significant figures = 6.72 liters per 100km

Answer:

f(-4) = -6

Step-by-step explanation:

- From the step wise function given, -4 is in range of the first function;

[tex]{ \tt{f(x) = - {(x + 1)}^{2} + 3 }} \\ \\ { \tt{f( - 4) = - \{( - 4) + 1) {}^{2} + 3}} \\ \\ { \tt{f( - 4) = - ( - 3) { }^{2} + 3}} \\ \\ { \tt{f( - 4) = - 9 + 3}} \\ \\ { \tt{f( - 4) = - 6}}[/tex]

Answer:

f(- 4) = - 6

Step-by-step explanation:

f(- 4) with x = - 4 is in the interval - 4 ≤ x < - 1 , then f(x) = - (x + 1)² + 3

thus

f(- 4) = - (- 4 + 1)² + 3

        = - (- 3)² + 3

         = - 9 + 3

        = - 6

then f(- 4) = - 6

The number of different selections that a customer can make is of 210.

To calculate the number of different selections that the customer can make, we need to verify if the order of the selections matters or not, then:

In the context of this problem, the order does not matter, hence the combination formula is used.

The number of combinations, from a set of n elements, of x elements, is given according to the following rule:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this problem, the number of selections is of 4 samples from a set of 10 samples, hence it is calculated as follows:

Answer:

x = 2

Explanation:

The given expression is

7x - 4 - 3x = -3x + 10

First, we need to add the like terms on the left side

(7x - 3x) - 4 = -3x + 10

4x - 4 = -3x + 10

Add 4 to both sides

4x - 4 + 4 = -3x + 10 + 4

4x = -3x + 14

Add 3x to both sides

4x + 3x = -3x + 14 + 3x

7x = 14

Finally, divide by 7

7x/7 = 14/7

x = 2

Therefore, the answer is x = 2

Answer:B 66.72

Step-by-step explanation:

complementary means if two angles are added up they will equal 90. we and eliminate d cause 23.28+23.28=46.56 so d is wrong now let's try c 46.56+23.28=69.84 so c is wrong cause it doesn't equal 90 now let's try a 156.72+23.28=180 its wrong since we are using complementary angles instead of supplementary angles Supplementary are angle two angles that add up to 180. so that just leaves b cause 23.28+66.72=90. i hope this helps and i made sure to explain it as best as i can have a great day

The solution is Option B.

The measure of the complementary angles are 66.72° and 23.28°

When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.

Let the first angle and second angle be a and b respectively such that

a + b = 90°

Given data ,

Let the first angle be represented as A

Now , the value of A is = 23.28°

Let the second angle be represented as B

Now , the value of B is = B

The angles A and B are complementary ,

So , A + B = 90°   be equation (1)

Substituting the values in the equation , we get

23.28° + B = 90°

On simplifying the equation , we get

Subtracting 23.28° on both sides of the equation , we get

B = 90° - 23.28°

B = 66.72°

Therefore , the value of B is 66.72°

Hence , the measure of the angle is 66.72°

The corresponding equation is 4q + 3p = 22.

What is the slope of a line ?

The ratio of the change in the y coordinate to the change in the x coordinate is known as a line's b in mathematics.

Y and X, respectively, stand for the net change in the y-coordinate and the net change in the x-coordinate. Locate two locations along the chosen line and find their coordinates.

Find the y-coordinate difference between these two places (rise). Find the difference between the x-coordinates of these two points (run). Subtract the difference in y-coordinates from the difference in x-coordinates (rise/run or slope).

The slope is defined as the relationship between the rise, or vertical change, between two points and the change, or horizontal change, between the same two points and can be represented as an equation.

Given that, coordinates are (p, 1/2) and (-8, q), slope is 3/4.

m = (y2 - y1)/(x2 - x1)

34 = (q - 1/2)/-8 - p

-24 - 3p = 4q - 2

4q + 3p = 22

The value of the x-intercept is 6, the y-intercept is 75, and the value of the slope is -25/2.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The x-intercept from the graph(where y = 0)

The x-intercept = 6

The y-intercept from the graph(where x = 0)

The y-intercept = 75

The slope can be found using two points: (0, 75) and (2, 50)

[tex]\rm m =\dfrac{50-75}{2-0}[/tex]

m = -25/2

Thus, the value of the x-intercept is 6, the y-intercept is 75, and the value of the slope is -25/2.

Equation of parallel line:
[tex]y = -5x + 6[/tex]

Equation of perpendicular line:
[tex]y = \dfrac{1}{5}x - \dfrac{22}{5}[/tex]

Step-by-step explanation:

Parallel lines have same slope

Slope of y = -5x + 9 is -5

Parallel line will also have slope -5

Equation is y = -5x + b where b is the y intercept to be determined

Since line passes through (2, -4) these values of x and y must satisfy the equation for the parallel line

Plugging in we get
-4  = -5(2) + b

-4 = -10 + b

b = 10 - 4 = 6

Equation of parallel line is y = -5x + 6

Perpendicular lines have slope = negative of reciprocal of each other

Original line has slope -5

Perpendicular line will have slope -(-1/5) = 1/5

Equation of perpendicular line is
y = -1/5 x + b

Plugging in (2, -4)

=>   -4 = 1/5(2) + b

=>    -4 = 2/5 + b

==> -4 - 2/5 = b

b = -22/5

Equation of perpendicular line is
y = (-1/5)x - 22/5

Applying properties of exponents, the equivalent expression is given as follows:

[tex](5^{-2})^{5} \times 5^4 = 5^{-6}[/tex]

The expression is given as follows:

[tex](5^{-2})^{5} \times 5^4[/tex]

First the power of power rule is applied, which states that if we have a base elevated to multiple powers, the base is kept while the powers are multiplied, hence:

[tex](5^{-2})^{5} = 5^{-10}[/tex]

(as -2 x 5 = -10)

Then the expression is written as follows:

[tex](5^{-2})^{5} \times 5^4 = 5^{-10} \times 5^4[/tex]

Now we have the multiplication of two terms with the same base and different exponents, meaning that we keep the base and add the exponents.

Hence the equivalent expression is given as follows:

[tex]5^{-10} \times 5^4 = 5^{-6}[/tex]

(as -10 + 4 = -6).

The 20 in. by 20 in. cardboard used make the box by cutting out squares of length x from the corners gives;

The dimensions that will yield maximum volume are;

Length =

The dimensions of the cut square that gives the maximum volume is approximately 3.3 feet, while the dimensions of the box are;

Length; 13.3 feet

Width; 13.3 feet

Height; 3 feet

The maximum volume of the box is approximately 592.6 ft³

The maximum value of a function is the peak or highest point on the graph of the function.

The volume, V, of a box of Length, L, Width, W and Height, H, is given by the formula;

V = L×W×H

The length, width, and height of the box obtained by cutting a square of side length, x from the corners are;

Height of the box formed = x

Length of the cardboard box = 20 - 2•x

Width of the cardboard box = 20 - 2•x

The volume of the box is therefore;

V(x) = (20 - 2•x)•(20 - 2•x)•x = 4•x³ - 80•x² + 400•x

At the maximum point, we have;

V'(x) = (3×4)•x² - (2×80)•x + 400 = 0

V'(x) = 12•x² - 160•x + 400 = 0

Which gives;

3•x² - 40•x + 100 = 0

(3•x - 10)•(x - 10) = 0

Therefore;

[tex] \displaystyle{x = \frac{10}{3} }[/tex] and x = 10

When x = 10, we have;

V(10) = 4×10³ - 80×10² + 400×10 = 0

When x = 10/3, we have;

V(10) = 4×(10/3)³ - 80×(10/3)² + 400×(10/3) ≈ 592.6

Therefore, the dimensions of the box that gives the maximum volume is [tex] \displaystyle{x = \frac{10}{3} \approx 3.3}

The dimensions that yield maximum volume are therefore;

The maximum of the box is 592.6 ft³

The equation for the perpendicular bisector of the given line segment is y = 2x + 2.

Here, we are given a line segment with end points (3,−7) and (−9,−1)

Thus, the slope of the line can be calculated as-

(y1 - y2)/ (x2 - x1)

= (-1 + 7)/ (-9 - 3)

= 6/ -12

= -1/2

Now, since we the slope of 2 lines that are perpendicular to each other is negative of the reciprocal, thus-

slope of the perpendicular bisector = 2

Now, the midpoint of the given line segment will be-

{(x1 + x2)/2, (y1 + y2)/2}

= {(3-9)/2, (-7-1)/2}

= {-6/2, -8/2}

= (-3, -4)

Now, we can use the point slope form to find the equation of the perpendicular bisector-

(y- y1) = m(x - x1) where m is the slope and (x1, y1) is a point on the line.

⇒ (y+4) = 2(x+3)

y + 4 = 2x + 6
