Evaluate the expression 5(7 − 4)2 ÷ 3 + 11. (5 point)
ch4aika [34]
Remember PEMDAS.
Parentheses first, which is 3. So then that is 5 times 3 times 2 divided by 3 +11
Simplify, 15 times 2 divide 3 +11
30divide 3 +11
10+11
answer is 21

Your math teacher tells you that the next test is worth 100 points and contains 38 problems muitiple choices are worth 2 points
jeka94

Answer:

multiple choice have 30 questions

word problems have 8 questions

Step-by-step explanation:

x=multiple choice. y=word problems

2x+5y=100 ---eq1

x+y=38 ---eq2

y=38-x ---eq3

substitutet eq3 into eq1

2x+5(38-x)=100

2x+(-5x)+190=100

2x-5x=100-190

-3x=-90

x=-90/-3

x=30

substitute x to eq3

y=38-(30)

y=8

Consider the statement : Congruent triangles are always similar. Which of the following statements is an example of the statemen
swat32

Answer:

Yes, the congruent triangles are always similar. The following statements are applicable

1) Angles are the same, but sides are proportional to eachother.

2) Sides are the same size.

3)Corresponding angles and corresponding sides are congruent.

Step-by-step explanation:

Yes, they are similar.

For two triangles to be similar, it is sufficient if two angles of one triangle are equal to two angles of the other triangle. Note that if two angles of one are equal to two angles of the other triangle, the third angles of the two triangles too will be equal.

If two triangles are congruent then all corresponding sides as well as corresponding angles of one triangle are equal to those of other triangles. This can happen in four cases

1)- when all sides of triangles are equal,

2) - if one side and two angles of one are equal to one side and two angles of other triangle.

3) - if two sides and included angle of one triangle are equal to two sides and included angle of other triangle

4)- if in two right angled triangles, one side and hypotenuse of one triangle are equal to one side and hypotenuse of other triangle.

Observe that for triangles to be similar, we just need all angles to be equal. But for triangles to be congruent, angles as well as sides should be equal.

Hence, while congruent triangles are similar, similar triangles may not be congruent ( but the converse is not true) .

Which of the following would best represent a cosine function with an amplitude of 3, a period of pi/2 , and a midline at y = –4
Grace [21]
To transform the function f(x)= cos(x) to have the amplitude of 3, we need to multiply the constant 3 to the function f(x), so we have y=3f(x)

To transform the function f(x)=cos(x) to have the midline y=-4 we need to subtract f(x) by 4, so we have y=f(x)-4, 

To transform the function f(x)=cos(x) to have period of \frac{ \pi }{2}, we need to divide the original period 2 \pi by 4, so we have y=f(4x). Note that it is the 4x gives the effect of dividing the points on x-axes by 4 and the period is read on x-axes

Hence, the full transformation is given y=3f(4x)-4 which is the last option
