Answer:

Answer c:  1000

Step-by-step explanation:

Set f(x) = 2 log x - 6 = 0 as a first step in finding the zero or zeros.

2 log x - 6 = 0  becomes log x - 3 = 0 after dividing all three terms by 2.

Then log x = 3, and because "log x" has base 10, the value of x is 10^3, or 1000.

Answer: C. (-1, -4) and (4, 6)

Step-by-step explanation:

Answer:

a^(2+m)

Step-by-step explanation:

We can simply add the exponents together because they have the same base which will give us a^(2 + m).

Answer:

a^[2+m]

Step-by-step explanation:

When multiplying two polynomials with the same base but different exponents, we add the exponents because

a^m*a^n

= a^m+n

So,

a^2*a^m

= a^2+m

Since it can't be solved anymore this is the simplest form

Answer:

  -2 < w ≤ 6

Step-by-step explanation:

The inequalities you're asked to combine are ...

  -2 < w

  6 ≥ w

Turn one of these around so the "arrows" point in the same direction. (My preference is that they point to the left.) Now you have ...

  -2 < w

  w ≤ 6

You combine these by putting w in the middle:

  -2 < w ≤ 6

_____

Alternate solution

I like the above solution because it puts the components of the expression in the same (left-right) order as they appear on a number line. However, both inequalities can be turned around to get ...

  6 ≥ w > -2

Answer:

A.

Step-by-step explanation:

for a single element of x there is an element in y, so observing we see that no number is repeated in the ordinate x of the coordinates

Answer:

You would need 148 racks

Step-by-step explanation:

5,624 divided by 38 = 148

Answer:

12 cm

Step-by-step explanation:

x/36=5/15

x=36/3

x=12 cm

Answer:

x = 12

Step-by-step explanation:

As you can see here, the sides are proportional to each other. You can use ratios in order to find x.

15:5 = 36:x

Answer: Hyperbolic geometry

Step-by-step explanation:

Hyperbolic triangle is a non - Euclidean triangle in which the sum of the angles of the triangle is not up to 180 degrees. That is, less than 180 degree.

Euclidean geometry is the normal geometry that is being taught in school in which the sum of the angles of its triangle equals 180 degrees

While spherical geometry is a non euclidean geometry with sum of the angles of its triangle greater than 180 degrees.

Therefore, the triangle that has angle measures of 45°, 61°, and 70° is a non - Euclidean geometry which is hyperbolic geometry.

Answer:

hyperbolic geometry

Answer:

1125 in²  

Step-by-step explanatio1D

Assume that the staircase is three steps high, as in the diagram.

Each tread has a surface area of

10 in × 25 in = 250 in²

Each riser has a surface area of

5 in × 25 in = 125 in²

There are three treads and three risers, so the total surface area is

3 × 250 in² + 3 × 125 in² = 750 in² + 375 in² = 1125 in²

The surface area of the small staircase which is made such that the horizontal piece of each step 10 inches long and 25 inches wide is 1125 in².

Surface area of any solid or the 3 dimensional body is the area of each faces by which the solid body is enclosed. Surface area of a cuboid is the sum of total area of each face.

The image of the staircase is shown below. This small staircase is made so that the horizontal piece of each step 10 inches long and 25 inches wide.

Thus, the surface area of the trade of stair case is,

[tex]A_{t}=10\times25\\A_{t}=250\rm\;in^2[/tex]

Each step is 5 inches above the previous one. Thus, the surface area of the riser of stair case is,

[tex]A_{r}=25\times5\\A_{r}=125\rm\;in^2[/tex]

Total surface area of one step is,

[tex]A_{s}=3(A_{t}+A_{r})A_{s}=3(250+125)\\A_{s}=3(375)\\A_{s}=1125\rm\;in^2[/tex]

Hence, the surface area of the small staircase which is made such that the horizontal piece of each step 10 inches long and 25 inches wide is 1125 in².

Answer:

Kawaii, the problem is the comparison with the calculated time for Jillian and the actual time for Jillian to run the 7 miles.

%error=(calculated value - experiemental value)/calculated * 100%

%error=(95-80)/95*100%=15/95 *100% = 15.79 ≈ 16% error  

Note: 16% error is the approximate error because the numbers have 2 significant figures stated in the problem.

Step-by-step explanation:

Answer:

1.

If two angles are supplementary, their sum is 180 degrees.

Check: 10 + 170 = 180

=> Maryam's claim is correct

If two angles are complementary, their sum is 90 degrees.

Check: 81 + 9 = 90

=> Ailia's claim is correct

2.

As the definition:

Vertical angles have sides that form two pairs of opposite rays.

Adjacent angles have a common side and don't overlap.

=> As provided pair of angles, they are adjacent pair of angles.

=> Ahmed's statement is wrong, Saalem's statement is correct.

Hope this helps!

Answer:

50% if your looking at %

(2x+10)°+(4x+20)°= 180° ( linear pair)

2x+10+4x+20=180

=6x+30=180                     6x=180-30

6x=150

x= 150/6= 25

x=25

2x+10=50+10=60

4x+20=100+20=120

we can check if we did correct if the angles add up to 180 as they are a linear pair
