Answer:

  angle 1 = 108°

Step-by-step explanation:

You want the measure of angle 1, given the measure of angle 4 is 72° in the diagram.

Angles 1 and 4 are a linear pair, so are supplementary:

  angle 1 + angle 4 = 180°

  angle 1 + 72° = 180°

  angle 1 = 108° . . . . . . . subtract 72°

Okay, here we have this:

Considering the provided expression, we are going to simplify it, so we obtain the following:

Then by properties of exponents we get the following:

Finally we obtain that the given expression is equal to 6.

Answer:

The value of x is 3 cm

Step-by-step explanation:

x is 3 cm because we can take 3/2 and make it easier for us and turn it into 1 and 1/2. As you can see 6, is 1 and 1/2 of 4, so all we have to do is find out what x equals by finding out what is 1 and 1/2 of 2. 2 is already 1, so we take half of 2 and add it and we get our answer 3 cm.

The value of the estimated standard error for the following set of D scores 4, 8, 4, 4 is 1.

The standard deviation of a statistic's sample distribution, or an approximation of that standard deviation, is the statistic's standard error. The term "standard error of the mean" is used when referring to a statistic that is the sample mean.

Consider the following set of D scores,

4, 8, 4, 4

We will calculate ∑D and ∑D² to find the SS for the D scores.

Therefore,

∑D = 4 + 8 + 4 + 4

∑D = 20

∑D² = 4² + 8² + 4² + 4²

∑D² = 16 + 64 + 16 + 16

∑D² = 112

Now, the formula for the standard score is given as:

[tex]SS=\sum D^2- \frac{(\sum)^2}{n}[/tex]

SS = 112 - [ (20)² /4 ]

SS = 112 - 100

SS = 12

Now,

[tex]S_{D}=\sqrt{\frac{SS}{n-1} }[/tex]

[tex]S_{D}=\sqrt{\frac{12}{4-1} }[/tex]

[tex]S_{D}=\sqrt{4}\\ S_{D}=2[/tex]

[tex]S_{\overline D}=\frac{S_{D}}{\sqrt{n} }[/tex]

[tex]S_{\overline D}=\frac{2}{\sqrt{4} }[/tex]

[tex]S_{\overline D}=\frac{2}{2}=1[/tex]

Hence, the standard error of the set of D scores is 1.

The change in temperature between the two readings as measured by Miguel is 18.7°F  .

In the question ,

the temperature  readings on the Miguel is

Average low temperature = -8.5°F

Average high temperature = 10.2°F

the change in the temperature , is given by the difference between the two reading .

which means

Change in temperature = Average high temperature - Average low temperature .

Substituting the values of average high and average low reading of the temperature from above ,

we get ,

Change in temperature = 10.2 -(-8.5)

= 10.2 + 8.5

= 18.7

The points on the x-axis that are 12 units away from the point (3,-6) is       found to be  3 ±  [tex]6\sqrt{3}[/tex].

r² = (x - h)² + (y - k)²is the standard equation for a circle, where (h,k) are the coordinates of the circle's center and r is the radius.

We must locate all points on the x-axis that are 12 units away from the starting point (3,-6).

Let these points be (x,0)

All points 12 units away from the point (3,-6) form a circle with a radius of 12 and a center at (3,-6). The formula would be as follows:

r² = (x - h)² + (y - k)²

12² = (x-3)² + (0+6)²

144 = (x-3)² + 36

(x-3)² = 108

x-3 = ± [tex]\sqrt{108}[/tex]

x = ± [tex]\sqrt{108}+3[/tex]

x = 3 ± [tex]6\sqrt{3}[/tex]

Therefore, the points on the x-axis 12 units away from point (3,-6) is  calculated as  3 ± [tex]6\sqrt{3}[/tex].

Step-by-step explanation:

Answer: 23+42=42+23

how the heak is this a colledge question*_* i learned this in 2nd grade lol

We have rewritten 23 + 42 = 65 as 23 + 42 = 65 using the Commutative Law of Addition.

A number system is defined as a system of writing to express numbers.

The Commutative Law of Addition states that changing the order of the addends does not change the sum.

a+b=b+a

Therefore, we can rewrite 23 + 42 as 42 + 23, and the equation becomes:

42 + 23 = 65

or 42+23=23+42

So, we have rewritten 23 + 42 = 65 using the Commutative Law of Addition.

Hence,  we have rewritten 23 + 42 = 65 as 23 + 42 = 65 using the Commutative Law of Addition.

The maximum height reached by the ball is 22 feet

The ball stayed in the air for 1 second

A function can be defined as a rule, law or expression that shows the relationship between two identifiable variables:

Given the function:

h(t) = -16t² + 32t + 6

Where;

To determine the maximum height in feet that the ball reached, we would be required to substitute the value of t as 1

We have:

h(1) = -16(1)² + 32(1) + 6

expand the bracket

h(1) = -16 + 32 + 6

Add the values

h(t) = 22 feet

To determine the time, we have;

-16t² + 32t + 6 = 22

-16t² +32t + 6 - 22 = 0

Add like terms

-16t² +32t - 16 = 0

Factorize further

-16t² + 16t + 16t - 16 = 0

Factorize in pairs

16t( t - 1) + 16 ( t - 1) = 0

Then,

t - 1 = 0

t = 1 second

Thus, the maximum height is 22 feet

Factor of trinomial 8x+2x-3 is 4x-3(binomial).

The breaking or decomposition of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics. Complete factoring is a three-step process: If at all possible, factor a GCF from the expression. Try to factor a trinomial if you can. Factor as many times as you can using a Difference Between Two Squares. Factorizing is the practice of expressing a number or other mathematical object as the sum of a number of other, typically smaller or more basic items of the same kind.

Given Data

∠a=90° as the rays of the angles meet at the right angle that is 90°.One of the angle is 21, The remaining would be 90-21=69°.

When two straight lines or rays intersect at a common endpoint, an angle is formed. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."

A ray is a vector that extends from one point to another. A ray is typically defined in geometry as a half-infinite line (also known as a half-line) with one of the two points and taken to be at infinity.

The right angle is formed when two straight lines intersect at 90 degrees or are perpendicular to each other at the intersection. The symbol is used to represent a right angle.∠

Here, The total sum of angles is 90°.

one the value is 21°. The value of adjacent angle would be,

remaining angle=90-21
