Answer the following NEED ANS ASAP giving u 23points

Answer:

The first one is correct

Step-by-step explanation:

a^2-1 + A+1

Since the -1 and +1 cancel out that leaves us with just a^2+a

Answer:

The answer is d

Step-by-step explanation:

[tex]a^{2} -1 + a + 1\\[/tex]

To add variables you count how many variables there are, and in this case, there are two a's

so it is going to be [tex]2a^{2}[/tex]

and 1 - 1 = 0

The answer would be [tex]2a^{2}[/tex]. Thank you

Given:

The figure of a right triangle.

To find:

The value of x.

Solution:

In a right triangle,

[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]

In the given right angle triangle,

[tex]\tan 52^\circ=\dfrac{x}{35}[/tex]

[tex]1.2799\times 35=x[/tex]

[tex]44.7965=x[/tex]

Approximate the value to two decimal places.

[tex]x\approx 44.80[/tex]

Therefore, the value of x is about 44.80 units.

Answer:

A, or "The height does not lie on the base because it's perpendicular to the base."

Step-by-step explanation:

EDGE 2021

Option A is correct, the height does not lie on the base because it is perpendicular to the base.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given that Jalen says that the height, radius, and diameter of a cone lie entirely on the base of the cone.

We have to find the Jalen’s error.

As we know that height does not lies on the base because it is perpendicular to the base.

The Jalens error is that height does not lie on the base because it is perpendicular to the base is a error statement.

Hence, option A is correct, the height does not lie on the base because it is perpendicular to the base.

Step-by-step explanation:

Take the time for history assignment and subtract the time for her English assignment

3/5 - 1/4

Get a common denominator of 20

Answer:

C = 4 pi ft

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

Solving for r

4 pi = pi r^2

Dividing each side by pi

4 = r^2

Taking the square root of each side

sqrt(4) = sqrt(r^2)

2 = r

Now we can find the circumference

C = 2 * pi *r

C = 2*pi*2

C = 4 pi ft

Answer:

Third turn point = 21 points

Step-by-step explanation:

Given:

First turn point = 12

Second turn point = 15

Find;

Third turn point

Computation:

First turn point = 12

Assume;

Point for outer circle = a

Point for inner circle = b

So,

3a = 12

Point for outer circle = 4 point

Second turn point = 15

So,

2a + b = 15

2(4) + b = 15

Point for inner circle = 7

Third turn point = 3 x 7

Third turn point = 21 points

Answer:

x = [tex]29^{o}[/tex]

Step-by-step explanation:

Looking at the right triangle we see two congruent sides, which means that we can find the angles:

180 - 64 = 116° for both bottom angles of the right triangle, so 58° (116°/2).

Looking at the middle angle we know that left corner from the left triangle is 58° so the angle in the middle would be 180 - 58 = 122°.

Since the right triangle equals to 180° then we can find the missing values including x:

180 - 122 = 58° is the total angle for each corner of the right triangle. So x would be 58/ 2 = 29°.

Therefore x = 29°.

Answer:

72 sqrt(3) ft^2

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

We can find the height by

tan theta = opp /adj

tan 60 = h /12

12 tan 60 = h

12 sqrt(3) = h

Then we can find the area

A = 1/2 bh  where b is the length of the base and h is the height

A = 1/2 ( 12) ( 12 sqrt(3))

A  = 72 sqrt(3) ft^2

Answer:

g(x) = 7(-x)³

Step-by-step explanation:

The cubic parent function is given as; f(x) = x³

Now, we are told that it reflects across the y-axis. This means that the new function will take the form;

g(x) = f(-x)

Thus, the new function is;

g(x) = (-x)³

Now,we are told that this new function stretches by multiplying by 7. Thus, we now have;

g(x) = 7(-x)³

Answer:

  C

Step-by-step explanation:

We assume you want these in order by angle measure in some consistent units. Degrees is a reasonable unit to use here.

  π radians = 180°

Substituting 180° where you see π, you find the angle values to be ...

  2π = 2(180°) = 360°

  7π/6 = 7/6(180°) = 210°

  π/4 = (1/4)(180°) = 45°

Then the angles from least to greatest are ...

  38°, 45°, 80°, 210°, 360°

or

  38°, π/4, 80°, 7π/6, 2π . . . . matches the third choice
