Answer:

A

Step-by-step explanation:

because for the sides to make a triangle the sum of the two shorter sides must be greater than the longest

Answer:

A, 5, 7, and 9

Step-by-step explanation:

There is a rule that states that the two shorter sides of a triangle have to be greater than the largest side.

A is correct because 5 + 7 > 9

B is incorrect because 5 + 3 = 8

C is incorrect because 1 + 3 = 4

D is incorrect because 4 + 4 < 9

I hope this helps.

Answer:

x = -4

Step-by-step explanation:

Square both sides:

[tex](\sqrt{-5-2x})^2 =(\sqrt{-1-x} )^2[/tex]

The square root and the square will cancel to leave simply the argument within the square root:

-5 - 2x = -1 - x

Now simply isolate the variable x:

x = -5 + 1 = -4

Check to see if x = -4 will work:

[tex]\sqrt{-5-2*(-4)} =\sqrt{-1-(-4)}[/tex]

[tex]\sqrt{3} =\sqrt{3}[/tex]

This works, so we know that x = -4 is a solution.

Hope this helps!

Answer:

Number of bacteria at 11:53 for 53 min = [tex]2^{53}[/tex]   = 9.007199 × [tex]10^{15}[/tex]  

fraction that is full = [tex]2^{-7}[/tex]

Step-by-step explanation:

solution

Number of bacteria is express as here

Number of bacteria = [tex]2^t[/tex]    ............1

so

bacteria at 1 min , 2 min and 3 min are

Number of bacteria at 1 min = [tex]2^1[/tex] = 2

Number of bacteria at 3 min = [tex]2^2[/tex] = 4

Number of bacteria at 3 min = [tex]2^3[/tex]  = 8

and

as that Number of bacteria at 11:53 is for 53 min is

Number of bacteria at 11:53 for 53 min = [tex]2^{53}[/tex]   = 9.007199 × [tex]10^{15}[/tex]  

and

bottle is full at 12:00

so Number of bacteria at 12:00 for 60 min = [tex]2^{60}[/tex]  

so fraction that is full = [tex]\frac{2^{53}}{2^{60}}[/tex]

fraction that is full = [tex]2^{-7}[/tex]

A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.

Number of bacteria present in bottle at 11:53  are [tex]2^{53}[/tex].

At that time, fraction [tex]2^{-7}[/tex] or 0.00781 of bottle is full.

Since, single bacterium is placed in a bottle at 11:00am. It grows and at 11:01 divides into two bacteria. These two bacteria each grow and at 11:02 divide into four bacteria. Which grow and at 11:03 divide into eight bacteria.

So, a sequence is obtained  1, 2, 4, 8, 16, 32, 64, .........

We can also write as,

At 11:00 am,    [tex]2^0[/tex] bacteria

At 11:01 am,    [tex]2^1[/tex] bacteria

At 11:02 am,   [tex]2^2[/tex]  bacteria

Similarly,  At 11:53 am, Number of bacteria present in bottle are [tex]2^{53}[/tex].

When the bottle will be full, that time number pf bacteria will be [tex]2^{60}[/tex].

S0, fraction of bottle is full at 11:53 is   [tex]2^{53} /2^{60} = 2^{-7} = 0.00781[/tex]

Answer:

V =96 pi

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h

Where r is the radius and h is the height

V = 1/3 pi (6)^2 *8

V = 1/3 pi (36)8

Answer with Step-by-step explanation:

We are given that height of projectile after t seconds is given by

[tex]h(t)=96t-16t^2[/tex]

a.h(t)=144 ft

[tex]144=96t-16t^2[/tex]

[tex]16t^2-96t+144=0[/tex]

[tex]t^2-6t+9=0[/tex]

[tex]t^2-3t-3t+9=0[/tex]

[tex]t(t-3)-3(t-3)=0[/tex]

[tex](t-3)(t-3)=0[/tex]

t-3=0

t=3

After 3 s, the height of the project will be 144 feet in the air.

b.h(t)=0

[tex]96t-16t^2=0[/tex]

[tex]16t(6-t)=0[/tex]

[tex]16t=0\implies t=0[/tex]

[tex]6-t=0\implies t=6[/tex]

At t=0, the initial position of projectile

At t=6 s , the projectile will hit the ground.

Step-by-step explanation:

The value with the exponent is the "multiplier". It is 0.05.

This value is less than 1, so the function represents decay.

The initial value is the number that multiplies the exponential term. It is the value of A when t=0: 250.

The volume of Mya's lunchbox can be calculated by multiplying its length, width, and height. However, the dimensions were not provided in the question.

The volume of a three-dimensional object like Mya's lunchbox can be found by multiplying the object's length, width, and height together. If Mya's lunchbox is a rectangular prism, for instance, and we know its measurements, we can calculate its volume using the formula Volume = Length x Width x Height. However, the question didn't provide the necessary dimensions of the lunchbox. Therefore, you need to provide the dimensions of the lunchbox for me to be able to help you calculate its volume.

Answer:

B (i do also slightly lean towards C, but i'm pretty sure it would be B because it gives a specific measurement)

Step-by-step explanation:

If all angles that are either adjacent or opposite are supplementary, all angles must be 90°

If at all times adjacent sides are 5 inches, all sides are equal.

Knowing this, it has to be a square because all angles would be 90° and all sides would be equal.

To reflect triangle A across the line y = 1, determine the corresponding points and apply symmetry properties. By understanding geometric transformations and symmetry, you can accurately visualize the new position of the triangle.

Reflecting triangle A in the line y = 1 involves transforming the triangle's position by flipping it over this horizontal line. This reflection will create a new image of the triangle across the line y = 1.

To reflect triangle A in y = 1, you need to locate the corresponding points across the line concerning their distance from the line itself. For instance, a point (x, y) would transform to (x, 2 - y) after reflection across y = 1.

Understanding symmetry properties and geometric transformations is crucial in reflecting shapes across lines, helping to visualize changes in position accurately.

Answer:

The starting balance of the 3rd year is $811.20.

The ending balance for the 3rd year is $843.65.

The interest earned in the 4th year is $33.75.

Step-by-step explanation:

750 × (1 + 4%)^n

750 × (1.04)^n

750 × 1.04² = 811.2

(End of second year, starting of third year)

750 × 1.04³ = 843.648

In third year: 843.648 - 811.2

= 32.448

750 × 1.04⁴ = 877.39392

Final answer:

To simplify the expression sqrt(18) + sqrt(50), find the square roots of 18 and 50 individually and then add them together.

Explanation:

To simplify the expression sqrt(18) + sqrt(50), we need to find the square roots of 18 and 50 individually and then add them together. The square root of 18 is approximately 4.2426 and the square root of 50 is approximately 7.0711. Adding these two values gives us approximately 11.3137. Therefore, the simplified expression is sqrt(18) + sqrt(50) = 11.3137.
