Answer:  [tex]\sqrt{65}[/tex]

Step-by-step explanation:

distance formula is [tex]\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1} )^{2}}[/tex]

take the 2points in the given (-4,-5) as ([tex](x_{1},y_{1} )[/tex]) and (3,-1) as [tex](x_{2},y_{2})[/tex]

and just substitute to get [tex]\sqrt{65}[/tex]

Understanding:

This can be easily solved by using the distance formula which is

[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }\\[/tex]

[tex]d:[/tex] distance

[tex](x_{1},y_{1}):[/tex] coordinates of the first point, in our case it is [tex](1,-5)[/tex]

[tex](x_{2},y_{2}):[/tex] coordinates of the second point, [tex](4,-1)[/tex]

Solution:

[tex]d=\sqrt{[(4)-(1)]^{2}+[(-1)-(-5)]^2}\\=\sqrt{(3)^2+(4)^2}\\= \sqrt{9+16} \\=\sqrt{25}\\= 5[/tex]

The distance between the two points is 5.

Step-by-step explanation:

Answer:

26.56 degrees

Step-by-step explanation:

The set up will give a right angles triangle

Given

The Horizontal distance = Adjacent side = 300ft

The height = Opposite side = 150ft

Using the SOH CAH TOA identity;

tan theta = opposite/adjacent

tan theta = 150/300

tan theta = 1/2

theta = arctan 1/2

theta = 26.56 degrees

Hence the angle of elevation is 26.56 degrees

Answer:

Area = a^4 + 10 a^2 + 6 a + 15

Step-by-step explanation:

Height: a^2+3

Width: a^2 +2a+5

Area of the entire rectangle = Height x Width

So we have to multiply both expressions and apply distributive property:

Area = (a^2 + 3) x (a^2 + 2a + 5)

Area = a^2 x (a^2 + 2a + 5) + 3 x (a^2 +2a + 5)

Area = a^4 + 2a^2 + 5a^2   + 3a^2 + 6a + 15

grouping terms of same power of a:

Area = a^4 + (2+5+3)a^2 + 6a + 15

Area = a^4 + 10 a^2 + 6 a + 15

Answer: 10 hours

Step-by-step explanation:

First and foremost, we should note that:

Speed = Distance / Time

Total destination = 610 miles

Loretta speed = 55 mph

Time to be used by Loretta = 4 hours

Loretta's distance = Speed × Time = 55 × 4 = 220 miles

The distance to be covered by her dad will then be:

= 610 - 220

= 390 miles

Her dad's average speed = 65 mph.

Time taken by her dad will be:

= 390 / 65

= 6 hours

The number of hours to be used by the family will then be:

Time taken by Loretta + Time taken by her dad

= 4 hours + 6 hours

= 10 hours

Answer:

Amphibians! In order for water-dwelling animals to adapt to life on land, many new adaptations had to take place. First, they needed to be able to breathe air instead of obtaining oxygen from water. And fins don't work well as legs! They needed to be able to move around well on land.

What group of animals begins its life in the water, but then spends most of its life on land? Amphibians! Amphibians are a group of vertebrates that has adapted to live in both water and on land. Amphibian larvae are born and live in water, and they breathe using gills. The adults live on land for part of the time and breathe both through their skin and with their lungs as their lungs are not sufficient to provide the necessary amount of oxygen.

There are approximately 6,000 species of amphibians. They have many different body types, physiologies, and habitats, ranging from tropical to subarctic regions. Frogs, toads, salamanders , newts, and caecilians are all types of amphibians.

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

you will have x+2 >1 and -(x+2) >1

remember when you divide by a negative, you switch the inequality sign. for the second expression, you switch from > to <

For the graph, shade in the areas where the red line is greater than 1 (the green line) on both sides of the V shape.

Answer:

The coordinates of the image of vertex G are (-5, 4)

Step-by-step explanation:

Let us revise some cases of reflection

From the given figure

∵ The line of the reflection is y = x

→ That means we will switch the coordinates of the point to find its image

∵ The coordinates of vertex G are (4, -5)

∴ The x-coordinate = 4 and the y-coordinate = -5

→ Switch the two coordinates

∴ The coordinates of its image G' are (-5, 4)

∴ The coordinates of the image of vertex G are (-5, 4)

Answer:

Hours of work= 3.5

Step-by-step explanation:

Giving the following information:

Allowance= $5

Hourly pay= $7.5

Desired profit= $31

To calculate the number of hours to work, we need to use the following formula:

Hours of work= shoveling pay / hourly pay

Hours of work= (31 - 5)/7.5

Hours of work= 26/7.5

Hours of work= 3.5

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

Given that:

Total number of cups of trail mix available for camping trip = [tex]6\frac{1}{2}[/tex]

Amount of one serving contains = [tex]\frac{3}{4}[/tex] cups

Number of people at the trip = 12

To find:

Whether each person will be able to get the servings?

Solution:

Here, we can find the total number of servings by dividing the total number of cups of trail mix with the amount of one serving.

First of all, let us convert the mixed fraction into fractional number.

[tex]6\dfrac{1}{2} = \dfrac{6\times 2+1}{2} = \dfrac{13}{2}[/tex]

Therefore, total number of servings available as per the given quantities:

[tex]\dfrac{\frac{13}2}{\frac{3}4}\\\Rightarrow \dfrac{13\times 4}{2\times 3} \\\Rightarrow \dfrac{26}{3}\\\Rightarrow \approx 8[/tex]

So, With this type of servings Zoey will be able to serve only 8 people.

Therefore, there is not enough servings.

Answer:

11

Step-by-step explanation:

Answer:

Step-by-step explanation:

First we need to calculate the Total surface area of the cylindrical tank as shown;

TSA of the tank = 2πr² + 2πrh  

TSA of the tank = 2πr(r+ h)  where;

r is the radius of the tank

h is the height

Given

radius = 5.5ft

height = 16ft

Get the surface area;

TSA = 2π(5.5)(5.5+ 16)

TSA = 2π(5.5)(21.5)

TSA = 2π(118.25)

TSA = 2(3.14)(118.25)

TSA = 742.61ft²

If a gallon of paint will cover 130ft^2 of​ surface, then the total number of paint needed will be;

Total number of paint needed = 742.61/130

Total number of paint needed = 5.7

For one coat we will need 5.7gallons of paint

For two coats we will need 2 * 5.7gallons = 11.4

Hence approximately 11 gallons of paints will be needed for the two coats
