Step-by-step explanation:
Answer:
12 m
Step-by-step explanation:
Given that the design, ABCD, was dilated to get a photocopy, EFGH, a scale factor or ratio was multiplied by the original lengths of the design to get the new measurement of the photocopy.
Thus, we are given the ratio, CD:GH = 2:3.
This means, any of the corresponding lengths of both figures would be in that same ratio.
Using the ratio of the design to the photocopy, 2:3, we can find the length of side EH of the photocopy.
The corresponding side of EH in the design is AD = 8m. Thus, AD to EH = ⅔
Cross multiply
Divide both sides by 2 to make EH the subject of formula
The length of side EH = 12 m
Answer:
f(-3) = -3
Step-by-step explanation:
replace x with -3 and solve
(-3)^4 = 81
3(-3)^3 = -81
(-3)^2 = 9
6 = 6
now solve
x^4 + 3x^3 – x^2 + 6
81 + (-81) - 9 + 6
-9 + 6
-3
The value of tangent a in the right triangle in which , cosine a = 0.352 and sine a = 0.936 is 2.659.
<h3>What are the trigonometric ratios?</h3>
Trigonometric ratios for a right angled triangle are from the perspective of a particular non-right angle. The value of tangent of angle is equal to the ratio of sine of that angle to the cosine of that angle.
Here, θ is the angle.
The value of angle given in the problem are,
- Cosine a = 0.352
- Sine a = 0.936.
Put these values in the above fromula as,
Hence, the value of tangent a in the right triangle in which , cosine a = 0.352 and sine a = 0.936 is 2.659.

The phrases that can be represented as the algebraic expression, 3n - 3 are: <em>Option 3 and Option 5.</em>
Let's translate each of the given phrases to algebraic expressions in order to determine which of them can be represented as 3n - 3.
<em>Option 1:</em>
3 fewer than n is represented as, n - 3
<em>Option 2:</em>
difference between n and 3 is represented as, n - 3.
<em>Option 3:</em>
3 times n is 3n
3 fewer than 3n is represented as 3n - 3.
<em>Option 4:</em>
product of 3 and n is represented as 3n.
<em>Option 5:</em>
3 less than 3n is represented as 3n - 3.
Therefore, the phrases that can be represented as the algebraic expression, 3n - 3 are: <em>Option 3 and Option 5.</em>
