Answer:

g(-5)=46

Step-by-step explanation:

given that function is,

g(k) = 2k² - 4,

and we find the value of g(-5)

so,

g(-5)=2(5)^2-4

simpley put -5 in place of k

g(-5)=2×25-4

g(-5)=46

Answer:

g(-5) = 46

Step-by-step explanation:

Given function:

[tex]g(k)=2k^2-4[/tex]

To find g(-5), substitute k = -5 into the given function:

[tex]\begin{aligned}\implies g(-5)&=2(-5)^2-4\\&=2(25)-4\\&=50-4\\&=46\end{aligned}[/tex]

Here, we want to check for the relationship between the image and its pre-image

The pre-image is (x,y)

The image is (3x,3y+5)

As we can see, the pre-image is not similar

This is because the transformation applied to the two values are not same

Thus, we have that;

No, the image is not similar to the pre-image as the translations applied to both coordinates are not same

The pre-image was transformed by dilating the x-coordinate of the pre-image by 3 units while the y-coordinate was transformed by dilating the y-coordinate of the pre-image by 3 and translating it upward by 5 units

The slope of a line perpendicular to the line 6x + 8y = -128 is 4/3.

Given,

The equation of a line = 6x + 8y = -128

We have to convert this into standard form of linear equation, y = mx + b :

So,

6x + 8y = -128

Add -6x to both sides,

6x + 8y - 6x = -6x - 128

Now,

8y = -6x - 128

Divide 8 on both sides

8y/8 = (-6x - 128) / 8

We get,

y = -6/8x - 16

Here, this is in standard form of linear equation.

Here slope of line, m₁ = -6/8

We have to find the slope of line(m₂) which is perpendicular to the given line.

If the line is perpendicular, the slope(m₂) will be the negative reciprocal of the slope(m₁) of the given line.

That is,

Slope of line, (m₂)= -(m₁) =  - (-8/6) = 8/6 = 4/3

In order prove that the triangles are similar by the SAS similarity theorem, it needs to be proven that A. J measures 60°.

The SAS Similarity Theorem states that two triangles are similar if their included angles are congruent and their two sides are proportionate to one other. Triangle congruence and resemblance are both criteria for SAS.

The triangles are congruent if two sides and the included angle of one triangle are equivalent to two sides and the included angle of another triangle.

In this case, the length of side FE is 40 and the length of side IH is 20. This gives a value of 60. Therefore, J should measure 60°.

In conclusion, the correct option is A.

The amount of weight lost will be equal to 4.72%.

Percentage may be defined as a form of expressing a number as a fraction of hundred. To find the percentage of a number we divide the number by the total amount and then multiply the answer with hundred. The initial weight of the casting was 148 lb and the final weight is 141 lb. To find the percentage we use the formula

Percentage lost = [(Final weight - Initial weight)/Initial weight] × 100

Percentage lost = [(141 - 148)/148] × 100

Percentage lost = ( -7/148) × 100

Percentage lost = -0.0472 × 100

Percentage lost = -4.72% and since we write the absolute value therefore, Percentage lost = 4.72%.

Then, to solve the exercise, we need to know the slope of each line. The slope of a line is the measure of the steepness of a line.

The graph shows that the red line has a greater steepness than the blue line. Thus, the lines have different slopes. Also, two lines are parallel if they have the same slope. Since these lines have different slopes, they are not parallel.

Therefore, student B is correct because the lines are not parallel, so they will intersect.
