Step-by-step explanation:

Setting f(x) = -(x + 3)(x + 1) = 0 leads to identifying two roots/solutions of this equation:  x = -3 and x = -1.  The axis of symmetry is a vertical line halfway between these two roots:  x = -2.  This x = -2 is also the x-coordinate of the vertex.  Evaluating f(x) = -(x + 3)(x + 1) at x = -2 gives us the y-coordinate of the vertex:  y = -(-2 + 3)(-2 + 1) = -(1)(-1) = 1.

In summary, the vertex is at (-2, 1) and the two x-intercepts are (-3, 0) and (-1, 0).  The y-intercept is found by  setting x = 0 and finding y:  

f(0) = -(0 + 3)(0 + 1) = -3, or (0, -3)

Step-by-step explanation:

The area of a kite is the product of the diagonals divided by 2.

If the diagonals have lengths a and b, then area = ab/2

area = ab/2

a = horizontal diagonal = 2 m + 6 m = 8 m

b = vertical diagonal = 3 m + 3 m = 6 m

area = (8 m)(6 m)/2 = (48 m^2)/2 = 24 m^2

Answer:

Two angles of a quadrilateral : 220 and 90 deg.

The other two angles (x and y) are in ratio 2:3.

We have:

x + y = 360 - 220 - 90 = 50 (property of sum of 4 angles in quadrilateral)

x/y = 2/3 => x = 2y/3

=>2y/3 + y = 50

=> 5y/3 =50

=> 5y = 150

=> y = 30

=> x = 2 x 30/3 = 20

=> Two other angles are 20 and 30 deg

Step-by-step explanation:

The problem involves calculating the speed of the current in a river using the given data: the speed of a boat in still water, the distance traveled downstream and upstream, and the total time taken. An application of the concept of relative speed helps solve the problem by setting up an equation reflecting the speeds during the downstream and upstream runs, then solving for the speed of the current.

The problem demonstrates an application of relative speed in the context of a boat moving in a stream. Let's denote the speed of the boat by 'b', the speed of the stream by 's', the time taken to move downstream by 't1', and the time taken to move upstream by 't2'. The speed of the boat in still water is given as 24 mph.

When moving downstream, the boat and the stream are going in the same direction, so their speeds add up: the actual speed will be b+s (24 mph + s). On the other hand, when moving upstream, the boat is going against the stream, so the actual speed is b-s (24 mph - s).

The total time taken to go 15 miles downstream and return is 80 minutes or 4/3 hours. Therefore, using the formula for time (time = distance/speed), we can set up the following equation: 15/(24+s) + 15/(24-s) = 4/3

Solving this equation will give us the value of 's', which represents the speed of the stream.

https://brainly.com/question/14362959

#SPJ12

The speed of the stream is 6mph.

To find the speed of the stream, we can use the concept of relative speed.

When the boat is going downstream (with the current), the effective speed is increased by the speed of the stream. So, the effective speed downstream is v + s

When the boat is going upstream (against the current), the effective speed is decreased by the speed of the stream. So, the effective speed upstream is V- s

1. Time taken downstream

[tex]\[ t_d = \frac{\text{Distance}}{\text{Speed}} = \frac{15}{v + s} \][/tex]

2. Time taken upstream

[tex]\[ t_u = \frac{\text{Distance}}{\text{Speed}} = \frac{15}{v - s} \][/tex]

3. Total time for the round trip

  The total time taken for the round trip is the sum of the time taken downstream and upstream.

[tex]\[ \frac{15}{v + s} + \frac{15}{v - s} = \frac{80}{60} \] (converted minutes to hours)[/tex]

Now, let's substitute v = 24 into the equations and solve for \( s \), the speed of the stream.

Once we have s  we can find the speed of the stream.

[tex]\[ \frac{15}{24 + s} + \frac{15}{24 - s} = \frac{4}{3} \][/tex]

Multiplying both sides of the equation by ( (24 + s)(24 - s) to clear the denominators:

[tex]\[ 15(24 - s) + 15(24 + s) = \frac{4}{3}(24 + s)(24 - s) \][/tex]

Taking the square root of both sides:

s= 6

Therefore, the speed of the stream is 6 mph.

Answer: Mara has a lot of yellow paint

Step-by-step explanation:

Mara has less green paint because 7 cups is the same as 56 fluid ounces and 56 is less than 64 (yellow paint)

Mara has 56 fluid ounces of green paint and 64 fluid ounces of yellow paint. Therefore, Mara has more yellow paint. The calculations involve converting units of measure for an accurate comparison.

To answer your question accurately, it would be necessary to convert the measurements to the same unit. Given that 1 cup is approximately 8 fluid ounces, Mara's 7 cups of green paint convert to 56 fluid ounces (7 cups * 8 ounces/cup).

Comparing this to the 64 fluid ounces of yellow paint, we find that Mara has more yellow paint.

The comparison was made by first converting the quantity of green paint from cups to fluid ounces for a direct, accurate comparison between the two quantities of paint. This kind of problem is a great example of why understanding units of measure is important in mathematics and in everyday life.

Answer:

surface area = 28 yard²

Step-by-step explanation:

given data

1 unit length of cube = 1 yd

solution

As given image shown that rectangular solid has length 5 units, width 2 units, and height 2 units.

so we get here surface area that is we get by area of each of its faces

we can see three face are

A front = L × W  = 2 × 2 = 4

A side = L × W  = 5 × 2 = 10

A top = L × W = 5 × 2 = 10

so here

surface area = ( front + back ) + ( left side + right side ) + ( top + bottom )   ................1

surface area = ( 2 × front ) + ( 2 × left side ) + ( 2 × top )

surface area = ( 2 × 4 ) + ( 2 × 10 ) + ( 2 × 10 )

surface area = 8 + 20 + 20

surface area = 28 yard²

Answer:

25

Step-by-step explanation:

Answer: 25

find the length of segment QU.  

First, we must find out what the coordinates are.

Q=(4,5) U=(4,10)

Then, Setup your equation by making the first coordinate pair equal. So,

Q= (4,5) would now equal Q=(5,5). That means we added 1. (when you add x ((x=the number you add to make equal)) you add x to the other side as well)

So, now we would add 1 (or how many you got) to U. Thus,

U=(4,10) would now equal Q=(5,10).

Next, set up the equation.

[tex]\sqrt{(Q)^{2} +(U)^{2}[/tex] (Q=(5,5) and U=(5,10).)

* You will now be subtracting the coordinates so, Q=(5-5) and U=(5-10)*

Next, Substitute the equation.

[tex]\sqrt{(5-5^{2} +(5-10)^{2}[/tex]

After, we solve.

[tex]\sqrt{0^{2} +(5-10)^{2}[/tex]

*the sum of two opposites equals 0. 5-5=0*

Next, Subtract (5-10).

[tex]\sqrt{0^{2} +(-5)^{2}[/tex]

Next, 0 raised to any positive power equals 0

[tex]\sqrt{0+(-5)^{2}[/tex]

Next, When adding or subtracting 0, the quantity does not change.

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

Next, Reduce the index of the radical and exponent 2.

[tex]|-5| = 5[/tex]

So, The length of segment is 5.

Now, find the length of segment Upper Q'U'​, multiply the length of segment QU by the scale factor.

scale factor in this equation is 5.

Now, multiply.

5·5 = 25

So, the length of segment Q'U' is 25.

The length of segment Q'U' after the dilation with a scale factor of 5 is 25 units.

To find the length of segment Q'U'  after the dilation with a scale factor of 5, we can calculate it step by step:

1. Calculate the new coordinates of Q'  and U'  after the dilation with a scale factor of 5 and center (0,0):

Q' coordinates: (4 5, 5 5) = (20, 25)

U' coordinates: (4 5, 10 5) = (20, 50)

2. Determine the distance between Q'  and U' using the distance formula:
- Horizontal distance: 20 - 20 = 0
- Vertical distance: 50 - 25 = 25

3. Calculate the length of segment

 using the Pythagorean theorem:
- Length = sqrt(0^2 + 25^2)
- Length = sqrt(0 + 625)
- Length = sqrt(625)
- Length = 25 units

Therefore, the length of segment Q'U' after the dilation with a scale factor of 5 is 25 units.

We have been given that a normal distribution has a mean of 186.4 and a standard deviation of 48.9. We are asked to find the range of value that represents the upper 2.5% of the data.

We know that upper 2.5% of data would be 97.5% of data.

We will use z-score formula to solve our given problem.  

[tex]z=\frac{x-\mu}{\sigma}[/tex], where,

z = z-score,

x = Random sample score,

[tex]\mu[/tex] = Mean,

[tex]\sigma[/tex] = Standard deviation.

Now we will use normal distribution table to find z-score corresponding to 97.5% area or 0.975.

We can see from the normal distribution table that z-score corresponding to  area 0.975 is [tex]1.96[/tex].

[tex]1.96=\frac{x-186.4}{48.9}[/tex]

Let us solve for x.

[tex]1.96\cdot 48.9=\frac{x-186.4}{48.9}\cdot 48.9[/tex]

[tex]95.844=x-186.4[/tex]

[tex]95.844+186.4=x-186.4+186.4[/tex]

[tex]282.244=x[/tex]

Therefore, the range [tex]x>282.244[/tex] represents the upper 2.5% of the data.
