Answer:

Step-by-step explanation:

Various scientific studies have been made regarding this topic and it has been stated that a child needs between 1,600 to 2,200 per day in order to develop a healthy immune system to survive in this world. This includes a balanced diet with all of the necessary nutrients. Including...

Protein
Calcium
Iron
Fats
Fiber
Vitamins

The vitamins would be

vitamin A
vitamin C
vitamin D

An example of a balanced diet that includes all of these nutrients and diversifies the food pyramid would be the following,

Yogurt with cereal, and seeds

Chicken with Pasta and Broccoli

Fruit Salad, including strawberries, oranges, mangos, etc.

Factor each expression. Problem: 2p^3 + 6p^2 + 3p + 9 Answer: (p + 3) (2p2 + 3)

oee [108]

Factor by grouping
$2p^3 + 6p^2 + 3p + 9$
$2 p^3+6 p^2+3 p+9=\left(2 p^3+6 p^2\right)+(3 p+9)=\left(2 p^2\right) (p+3)+3 (p+3)$
$2 p^2 (p+3)+3 (p+3)$
$(p+3) \left(2 p^2+3\right)$

what are the lengths of the legs of a right triangle in which one acute angle measures 19° and the hypotensue is 15 units long?

givi [52]

Refer to the diagram shown below.

Given:
m∠A = 19°
c = 15

By definition,
sin A = a/c
Therefore
a = c*sin A = 15*sin(19°) = 4.8835

cos A = b/c
Therefore
b = c*cos A = 15*cos(19°) =14.1828

Answer:
The lengths are 4.88, 14.18, and 15.00 (nearest hundredth)

Here’s a graph of a linear function. Write the equation that describes that function. Express it in slope intercept form.

MatroZZZ [7]

Answer:

y = $\frac{3}{4\\}$ x + 2

Step-by-step explanation:

To find the slope:

Find two spots where the line intersects and exact point. (-8,-4)(-4,-1)

Either count up & over or do y1-y2 / x1-x2 (-4+1)/(-8+4) -3/-4 3/4

The intercept is where it crosses the y-axis, in this case 2

Write the equation like this y = mx + b where m=slope & b=intercept

y = 3/4x + 2

Hi ! How to solve this question?

tester [92]

You should actually have

$-x^2-4x-10=-(x^2+4x+10)=-(x^2+4x+4+6)=-((x+2)^2+6)=-(x+2)^2-6$

Now, remember that $x^2$ is always non-negative, so $(x+2)^2\ge0$ for any value of $x$ . This means $-(x+2)^2\le0$ for any $x$ , and so

$-(x+2)^2-6\le0-6=-6$

i.e. f(x) is at most -6, and hence negative for all $x$ .

Whats the explicit formula sequence

weeeeeb [17]

An explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). It defines the sequence as a formula in terms of n.
