If 2/3 of the cards are face-up, then 2/3*12=8 cards are face-up. The remaining 12-8=4 cards are therefore face down.

The function h(x) = 12x8 + 49 is an even function. Which transformation of h(x) would result in a function that is neither even

Irina-Kira [14]

Answer: translation 8 units to the right

Step-by-step explanation:

An even function is a function such that:

h(x) = h(-x)

and the function is odd if:

h(-x) = -h(x)

Now, let's talk about transformations:

A) Reflection over the x-axis:

When we have a point (x,y) and we do a reflection over the x-axis, the reflected point will be:

(x, -y).

Then for the case of a function:

y = h(x).

then the reflection will be:

g(x) = - y = -h(x).

And if h(x) is even, -h(x) is also even, so this is not the correct option.

B) Vertical stretch by a factor of 7.

This is written as:

g(x) = 7*h(x).

then:

g(x) = 7*h(x)

g(-x) = 7*h(-x) = 7*h(x) = g(x)

the transformation is even.

C) Translation of 8 units to the right.

We can write this as:

g(x) = h(x - 8).

Then:

g(-x) = h(-x -8) = h(x + 8)

Then g(-x) is not equal to g(x)

and also g(-x) ≠ -g(x)

So in this case the transformation is neither odd or even.

C) horizontal compression by a factor of One-half.

This transformation is written as:

g(x) = h( (1/2)*x)

And, similar as the case of the vertical compression, in this case the transformation is also even.

Find the difference in length between a walking stick and a bumblebee PLS HELP HURRY

Tanya [424]

Difference between the lengths of walking stick and lengths of bumble bee is $3\frac{4}{8}$ inch.

Solution:

Given data represents the length of the insects.

Length of the walking stick = 4 in

Length of the bumble bee = $\frac{5}{8}$ in

Difference between their length

$$=4-\frac{5}{8}$

$$=\frac{4}{1} -\frac{5}{8}$

To make the denominator same, multiply and divide the first term by 8.

$$=\frac{32}{8} -\frac{5}{8}$

$$=\frac{32-5}{8}$

$$=\frac{27}{8}$

Now, change improper fraction into mixed fraction, we get

$$=3\frac{4}{8}$

Difference between the lengths of walking stick and lengths of bumble bee is $3\frac{4}{8}$ inch.

What is m angle 1? 35° 40° 55° 70°

gizmo_the_mogwai [7]

9514 1404 393

Answer:

(b) 40°

Step-by-step explanation:

Angle x and the one marked 70° are alternate interior angles, so are congruent. The sum of the two base angles of the isosceles triangle is ...

x° +x° = 70° +70° = 140°

So, the remaining angle 1 in the triangle is ...

180° -140° = 40°

∠1 = 40°
