Answer:

4.5

Step-by-step explanation:

tan A = [tex]\frac{opposite side}{adjacent side}[/tex]

tan 34° [tex]= \frac{x}{6.7}[/tex]

0.6745 = [tex]\frac{x}{6.7}[/tex]

0.6745 * 6.7 = x

x = 4.52

x = 4.5

Answer:

x = 50.8°

Step-by-step explanation:

We are given:

1.) Angle x

2.) Side opposite to angle x

3.) Hypotenuse

Therefore to find the angle x, we will use the sin inverse:

Sin(x) = Opposite / Hypotenuse

Sin(x) = 6.2/8

x = Sin⁻¹(6.2/8)

x = 50.8°

Hope this helps!

Answer:

d=13

Step-by-step explanation:

D = √(x2 - x1)2 + (y2 - y1)2

D = √(-6 - (-8))2 + (1 - 4)2

D = √(-6 + 8)2 + (-3)2

D = √(2)2 + (-3)2

D = √4 + 9

D = √13

Answer:

6

Step-by-step explanation:

Let the first number be x

Let the second number be y

x + 2y= 4............equation 1

2x +y= 11............equation 2

From equation 1

x + 2y= 4

x = 4-2y

Substitute 4-2y for x in equation 2

2x + y= 11

2(4-2y) + y= 11

8-4y+y= 11

8-3y= 11

-3y= 11-8

-3y= 3

y= -1

Substitute -1 for y in equation 1

x + 2y= 4

x + 2(-1) = 4

x-2= 4

x = 4+2

x = 6

Hence the first number is 6

Since the numbers are the same, you are allowed to add the exponents.

[tex] {7}^{7} \times {7}^{3} = {7}^{10} [/tex]

Answer:

[tex]7^{10}[/tex]

Step-by-step explanation:

The laws of exponents state that if two terms share a base they can be simplified. Specifically, the product exponent law says that if 2 like bases are being multiplied then the exponents can be added together. So, because the two bases are like and 7+3=10, the final answer is [tex]7^{10}[/tex].

The graph of the linear equation can be seen below.

Here we have the linear function:

y = 5x + 3

To graph this, we need to find two points on the equation and then connect them with a line.

By evaluating in 0 we get:

y = 5*0 + 3 = 3

So the point (0, 3) is on the line.

By evaluating on 1 we get:

y = 5*1 + 3 = 8

So we have the point (1, 8).

Now we just plot them and connect them with a line, the graph is the one below.

Answer:

6 and 10

Step-by-step explanation:

4+5+10= 19

19/3 is around 6.3333 and since our mean is 7 we will need a number higher than 6 so either 7,8,or 9

Also if our median is 6, six needs to be added

Let’s try using 6&7

4+5+6+7+10= 32/5- 6.4 NOT 7

4+5+6+8+10=33/5- 6.6- maybe 8

4+5+6+9+10= 34/5-6.8- maybe 9

4+5+6+10+10=35/5- perfect match!!!!

Answer:

0.75x=(total cost)

Step-by-step explanation:

Answer:

The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.

A function relating these variables is A(x) =0.75x .

So A(12) = 9, meaning 12 bagels will cost 9 dollars.

Step-by-step explanation:

If you add 5+4 you get 9

And if you multiple 5×4 you get 20

Answer:

x = 1

Step-by-step explanation:

First, combine like terms. Like terms are terms that share not only the same variable, but the same amount of that variable:

5x - 4 + 2x = 3

(5x + 2x) - 4 = 3

7x - 4 = 3

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Division

Addition

Subtraction

First, add 4 to both sides of the equation:

7x - 4 (+4) = 3 (+4)

7x  = 3 + 4

7x = 7

Next, divide 7 from both sides of the equation:

(7x)/7 = (7)/7

x = 7/7 = 1

x = 1 is your answer.

Answer:

x = 1

Step-by-step explanation:

5x - 4 + 2x = 3

7x - 4 = 3           (add the Xs together)

7x = 7                (add seven to both sides)

x = 1                  (divide both sides by 7)

[tex]s=20[/tex]

Step-by-step explanation:

By the Exterior Angle Theorem, we know that the exterior angle is equal to the sum of the two, opposite interior angles.

In other words:

Solve for s. Combine like terms:

[tex]4s=5s-20[/tex]

Subtract 5s from both sides:

[tex]-s=-20[/tex]

And divide both sides by negative one. Therefore:

The Gender Gap in STEM Fields: The Impact of the Gender Stereotype of Math and Science on Secondary Students' Career Aspirations

Elena Makarova1*, Belinda Aeschlimann2 and Walter Herzog3

1Institute for Educational Sciences, University of Basel, Basel, Switzerland

2Swiss Federal Institute for Vocational Education and Training SFIVET, Bern, Switzerland

3Institute of Educational Science, University of Bern, Bern, Switzerland

Studies have repeatedly reported that math and science are perceived as male domains, and scientists as predominantly male. However, the impact of the gender image of school science subjects on young people's career choice has not yet been analyzed. This paper investigates the impact of the masculinity image of three school subjects—chemistry, mathematics, and physics—on secondary students' career aspirations in STEM fields. The data originated from a cross-sectional study among 1'364 Swiss secondary school students who were close to obtaining their matriculation diploma. By means of a standardized survey, data on students' perception of masculinity of science school subjects were collected using semantic differentials. The results indicate that for both sexes, math has the strongest masculinity attribution, followed by physics as second, and, finally, chemistry with the lowest masculinity attribution. With respect to gender differences, our findings have shown that among female students, the attribution of masculinity to the three school subjects does not differ significantly, meaning that female students rated all subjects similarly strongly as masculine. Within the group of male students however, the attribution of masculinity to math compared to chemistry and physics differs significantly, whereas the attribution of masculinity to chemistry and physics does not. Our findings also suggest that gender-science stereotypes of math and science can potentially influence young women's and men's aspirations to enroll in a STEM major at university by showing that a less pronounced masculine image of science has the potential to increase the likelihood of STEM career aspirations. Finally, the paper discusses ways of changing the image of math and science in the context of secondary education in order to overcome the disparities between females and males in STEM.

Answer:

Option B

Step-by-step explanation:

Given the piecewise function, we see that there are two vertical asymptotes at lines x=-3 and x=3. Around the vertical asymptote x=-3, the limit of the function f(x) as x approaches -3 from the left side is ∞, and the limit of the function as x approaches -3 from the right side is -∞. The behavior of the function around the vertical asymptote x=3 is exactly the same. Therefore, option B is correct.

The statement which describes the behaviour of the function round the vertical asymptotes is b which is around x=-3+ limit of f(x)-=infinity and for limit f(x)+ is -x. Around x=3 the function behaves within the same manner as around x=-3.

Limit of a function describes the behaviour of a function as when the function behaves at a specific point.

We can see that there are two vertical asymptotes at lines x=-3 and x=3. round the vertical asymptote x=-3 the limit of the function as x approaches -3 from the left side is infinity and also the limit of the function as x approaches -3 from the proper side is -infinity.

Answer:

The 6th degree polynomial is [tex]p(x) = (x-1)^3(x-4)^2(x+3)[/tex]

Step-by-step explanation:

Zeros of a function:

Given a polynomial f(x), this polynomial has roots [tex]x_{1}, x_{2}, x_{n}[/tex] such that it can be written as: [tex]a(x - x_{1})*(x - x_{2})*...*(x-x_n)[/tex], in which a is the leading coefficient.

Zero 1 with multiplicity 3.

So

[tex]p(x) = (x-1)^3[/tex]

Zero 4 with multiplicity 2.

Considering also the zero 1 with multiplicity 3.

[tex]p(x) = (x-1)^3(x-4)^2[/tex]

Zero -3 with multiplicity 1:

Considering the previous zeros:

[tex]p(x) = (x-1)^3(x-4)^2(x-(-3)) = (x-1)^3(x-4)^2(x+3)[/tex]

Degree is the multiplication of the multiplicities of the zeros. So

3*2*1 = 6

The 6th degree polynomial is [tex]p(x) = (x-1)^3(x-4)^2(x+3)[/tex]
