Hence, in 23 days she will eat 1058 g of protein.

A rhombus have 4 sides and angles

it first must be proven to have 4 sides, or 4 angles

thats a definition for Quadrilateral

then correct option is D

(fog)(x) = 5x² - 15x + 61

The given functions are:

f(x) = 5x + 1

g(x) = x² - 3x + 12

(fog)(x) = f(g(x))

This means that we are substituting g(x) into f(x)

(fog)(x) = 5(x² - 3x + 12) + 1

(fog)(x) = 5x² - 15x + 60 + 1

This can be further simplified as:

(fog)(x) = 5x² - 15x + 61

This type of function is non linear.

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). A function, according to a technical definition, is a relationship between a set of inputs and a set of potential outputs, where each input is connected to precisely one output. You can tell if a relation is a function by looking at the inputs (the x-coordinates) and outputs (the y-coordinates). Keep in mind that each input has only one output in a function. A function is an equation with a single solution for y for each value of x. Each input of a particular type receives exactly one output when using a function.

Given,

f(x) = x²

This type of function is non linear.

The end behavior is:

as x ⇒ ∞ , y ⇒ ∞

x ⇒ -∞ , y ⇒ -∞

The function graphed is f(x) = (x -3)²

The formula for determining simple interest is expressed as

I = PRT/100

where

I = interest

P = principal or amount invested

T = time in years

R = interest rate

Considering the amount invested in her local bank,

P = 3760

R = 1.8

T = 5

I = (3760 x 1.8 x 5)/100 = 338.4

Considering the amount invested in online savings,

P = 2400

R = 5.3

T = 5

I = (2400 x 5.3 x 5)/100 = 636

After 5 years, the investment in the online savings account earned more interest.

The difference in interest earned is

636 - 338.4 = $298 to the nearest dollar

It has earned $298 more than the local bank's interest

The nominal interest rate compounded quarterly is 1.33%.

Given,

If an investment grew to $13,500 in 2 years.

and, the interest amount earned was $1,150.

To find the nominal interest rate compounded quarterly.

What is nominal interest rate?

The interest rate before inflation is referred to as the nominal interest rate.

Nominal can also refer to the advertised or stated interest rate on a loan, excluding any fees or interest compounding.

Now, According to the question:

Here given ,

P = $13500

i = ?

A = $1150

t = 2 yrs

n = 4 x 2 = 8

Formula of compound interest ,

A = P( 1 + I )ⁿ

$1150  = $13500 ( 1 + i ) ⁸

$1150 / $13500 = (1 + i)⁸

0.0851 = (1+ i) ⁸

1 +i = 8√.0851

1 + i = 2.33

i = 2.33 -1

i = 1.33 %

Hence, The nominal interest rate compounded quarterly is 1.33%.

The measurement that cannot be taken directly in 2-D is depth

What do you mean by measurement?

Measurement is the quantification of an object's or event's properties for comparison with other objects or occurrences. Measurement, in other terms, is the act of establishing how large or little a physical amount is in comparison to a fundamental reference quantity of the same sort. The scope and use of measurement are context and discipline dependent. Measurements do not apply to nominal qualities of things or events in natural sciences and engineering, which is compatible with the recommendations of the International Bureau of Weights and Measures' International lexicon of metrology. However, measures in other domains, such as statistics and the social and behavioral sciences, can have numerous levels.

5 2+3=5 (2) +5. (3) is a valid application of the distributive property.

What is a distributive property?
According to this property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Given that,

A. 5.2+3=5 (2+3)

B. 5 2+3=5 (2) +5. (3)

Distributive property

To answer this we have to apply the simple interest formula:

I =P x r x t

Where:

I= interest

P= Principal

R= Interest rate ( in decimal form)

t = time (years)

Replacing with the values given:

Interest= I

Principal = ?

Interest rate = 2/100 =0.02

time= 5 years

I = P x 0.02 x 5

I= 0.1P

Amount= P+I

A = P+0.1P

5,000= P+0.1P

5,000= 1.1P

5,000/1.1 =P

Answer: [tex](-\infty, -1) \cup (1, \infty)[/tex]

Step-by-step explanation:

The function is always positive when it has a positive leading coefficient (since that means the graph will open up), and when the discriminant is negative (meaning the graph will never cross the x-axis).

Condition I. Leading coefficient is positive

[tex]m^2 -1 > 0 \implies m < -1 \text{ or } m > 1[/tex]

Condition II. Discriminant is negative

[tex](2(m-1))^2 -4(m^2 -1)(2) < 0\\\\4(m^2 -2m+1)-8(m^2 -1) < 0\\\\4m^2 -8m+4-8m^2 +8 < 0\\\\-4m^2 -8m+12 < 0\\\\m^2 +2m-3 > 0\\\\(m+3)(m-1) > 0\\\\m < -3 \text{ or } m > 1[/tex]

Taking the intersection of these intervals, we get [tex]m < -1[/tex] or [tex]m > 1[/tex].
