Answer:

The range of the function y = 2cos x is -2 <y < 2 .

Step-by-step explanation:

We know that cos (0) = 1 and cos (π) = - 1 are the two extreme values which cos x assume when x ∈ R and it is also that cos (x) is a continuous periodic function with period 2π when x ∈ R ,

since ,

cos (x + 2π) = cos x

So, the range of the function y = 2cos x is -2 <y < 2 .

A rectangle has a length of x inches and a width 2 inches less than the length. If the dimensions were doubled, what would be th

Gelneren [198K]

Answer:

Option (4)

Step-by-step explanation:

Area of a rectangle = Length × width

If the dimensions of the given rectangle is doubled,

Area of the new rectangle = 2(Length) × 2(width)

= 4(Length × width)

= 4(x)(x - 2)

= 4[x² - 2x]

= 4x² - 8x

Therefore, Option (4) will be the correct option.

7/4x-5/6=5/8(x-2/3) what is the value of x?

Anit [1.1K]

Answer:

x = 0

Step-by-step explanation:

If, in fact, this is the polynomial you have:

$\frac{7}{4}x-\frac{5}{6}=\frac{5}{8}(x-\frac{2}{3})$ , then x = 0.

Begin by distributing the 5/8 into the parenthesis to simplify to:

$\frac{7}{4}x-\frac{5}{6}=\frac{5}{8}x-\frac{10}{24}$

The next thing to do would be to find the LCM and get rid of all those fractions! Each one of those denominators goes into 24 evenly, so we multiply every single term by 24:

$(24)\frac{7}{4}x-(24)\frac{5}{6}=(24)\frac{5}{8}x-(24)\frac{10}{24}$

Divide each denominator into 24 and you get:

$(6)7x-(4)5=(3)5x-(2)10$

Multiply all that to get

42x - 20 = 15x - 20

Combine like terms to get

27x = 0 so

x = 0

The square root of a number is greater than the square of the number. For what set of numbers is this true? (0, 1) [0, 1] [1, ꝏ)

vredina [299]

Answer:

(0,1)

Step-by-step explanation:

If you plug in f(x)= $\sqrt{x}$ and g(x)= $x^{2}$ into the calculator, you will find that from 0 to 1 that f(x) is rises above g(x). The parentheses are not [ ] because the question is not asking for greater than or equal to.
