Answer:

m<ACD = 50^{o}

Step-by-step explanation:

From the question given, ΔACD is a right angled triangle. Then we can apply one of the properties of a triangle to it.

In the triangle ACD:

<ACD + <DAC + <ADC = 180 (sum of angles in a triangle)

<ACD + 40 + 90 = 180

<ACD + 130 = 180

<ACD = 180 - 130

<ACD = 50^{o}

With the application of the property of the sum of interior angles of a triangle, the measure of <ACD is 50^{o}.

If f(x)= 10 sin(x) – 3 then f (30%) = ?
marissa [1.9K]

Answer:

The value of f(30) is equal to 2.

Step-by-step explanation:

The given expression is :

f(x)= 10 \sin(x) - 3

We need to find the value of f(30)

Put x = 30 in above expression.

So,

f(x)= 10 \sin(30) - 3\\\\=10\times \dfrac{1}{2}-3\\\\=5-3\\\\=2

Hence, the value of f(30) is equal to 2.

Ahmed wrote two numbers. The first number has a 7 in its tenths place. The second number has a 7 with a value that is 1,000 time
Stels [109]

Answer: In the hundreds place.

Step-by-step explanation:

1. You know that the first number has a 7 in its tenths place. This means that it is after the decimal point. You can write is as following:

x.7

Where x represents the other digits.

2. The second number has a 7 with a value that is 1,000 times greater than the value of the 7 in the first number, this means that you can know the place of the 7 in the second number if you multiply the first number by 1,000, or in other words, move the decimal point three places to the rigth. Therefore:

x.7*1000=7xx

3. As you can see, the 7 is in the hundred place in the second number.
