Nakia is an architect designing a house with a peaked roof. She is trying to decide what the limitations are on her design. If AB is 8 feet and triangle ABC will be isosceles, describe the possible lengths for AC.

Answer:

I think the answer is D.) 7/8 mile

Step-by-step explanation:

If you make the mixed numbers improper fractions. 2 and 1/8 is 17/8, 1 and 1/4 (2/8) is 10/8, then you subtract the numerators and keep the denomitators the same to get 7/8 mile (sorry if I spelt something wrong)

In the diagram, the set A represents the event of having an adequate supply of material A, and the set B represents the event of having an adequate supply of material B.

The overlap of A and B represents the event of having an adequate supply of both materials.

The set E represents the event of a shortage in material A, and the set F represents the event of a shortage in material B.

The net that represents this solid figure is diagram D.

A solid figure is a three-dimensional geometric shape that has length, width, and height. It is also called a three-dimensional or 3D figure. Some examples of solid figures include cubes, spheres, cylinders, cones, and pyramids.

Solid figures are different from two-dimensional shapes, which only have length and width. In contrast, solid figures have depth or thickness, making them more complex and interesting.

Solid figures can be classified based on their properties, such as the number of faces, vertices, and edges they have. For example, a cube has six faces, eight vertices, and 12 edges, while a sphere has no faces, vertices, or edges.

In this case, it has 2 squares and 4 rectangles. The appropriate diagram is D

Step-by-step explanation:

146+1=147

The sums, differences, product, and quotient of the functions and their domains are;

f(x) = √(16 - x^2), g(x) = √(x + 3)

f + g = √(16 - x^2) + √(x + 3)

Domain; [-3, 4]

f - g = √(16 - x^2) - √(x + 3)

Domain: [-3, 4]

f × g = √(16 - x^2) × √(x + 3) = √(-x³ - 3·x² + 16·x + 48)

f × g = √(-x³ - 3·x² + 16·x + 48)

Domain; [-3, 4]

f/g = √(16 - x^2)/√(x + 3) = √(16 - x^2)/(x + 3))

f/g = √(16 - x^2)/(x + 3))

Domai; [-3, 4] ∪ [1, 4]

f(x) = √(81 - x^q2), g(x) = √(x² - 16)

f + g = √(81 - x^2) + √(x² - 16)

Domain [-9, -4] ∪ [4, 9]

f - g = √(81 - x^2) - √(x² - 16)

Domain: [-9, -4] ∪ [4, 9]

f × g = √(81 - x^2) × √(x² - 16) = √(-x⁴ + 97·x² - 1296)

f × g = √(-x⁴ + 97·x² - 1296)

Domain: [-9, -4] ∪ [4, 9]

f/g = √(81 - x^2)/√(x² - 16)

Domain: [-9, -4] ∪ [4, 9]

The sum of two functions is obtained by adding the values of the functions at each point.

The sum of two functions is obtained by adding the values of the functions at each point. The domain of the sum is the intersection of the domains of the two functions, In this case, the domain of f + g is [-3, 4]

The difference of two functions is obtained by subtracting the functions values at each point. The domain of the difference is the intersection of the domains of the two functions. In this case, the domain of f - g is [-3, 4]

The product of two functions is obtained by multiplying the values of the functions at each point. The domain of the product of the functions is the domain of the intersection of the domains of the two functions. The domain of f × g is  [-3, 4]

The quotient of two functions is obtained by dividing the values of the functions at each point. The domain of the quotient is the same as the domain of the intersection of two functions, excluding any points where the denominators is zero. The domain of f/g is [-3, -1] ∪ [1, 4].

Answer:

1.65 pints

Step-by-step explanation:

If Tara used 6.6 pints of white and blue paint combined, and 3/4 of that amount is white paint, then we can find the amount of white paint she used by multiplying 6.6 by 3/4:

6.6 x 3/4 = 4.95

So Tara used 4.95 pints of white paint to paint her bedroom walls.

To find out how much blue paint she used, we can subtract the amount of white paint from the total amount of paint:

6.6 - 4.95 = 1.65

Therefore, Tara used 1.65 pints of blue paint to paint her bedroom walls.

a) The percentage of adults in the USA that have stage 2 high blood pressure is; 0.27%

b) The number of people that you will expect to have BP greater than 160 is; 54

a) if x is systolic blood pressure, then want to find probability that x ≥ 160.

The formula for z-score is;

z = (x - mean)/standard deviation

Thus;

z = (x - 119)/18

This is normally distributed with mean 0 and standard deviation 1

Transform x to z:

P(x > 160) = P(z > (160 - 119)/18)

= P(z > 2.78)

= P(z < -2.78)

= 0.0027 (from standard normal distribution table, which 0.27%.)

b)  Since probability of BP > 160 is 0.027.  

Then out of 2000 people, then 2000 * 0.027 = 54 people would have BP > 160.

The range of lengths Brett can use for the third piece of steel is 4 in. < x < 20 in.

The Triangle is a polygon with three line segments as its boundaries. That is the tiniest polygon imaginable. Three vertices, three internal angles, and three sides make up a triangle.

The triangle inequality theorem explains the connection between a triangle's three sides. This theorem states that for every triangle, the sum of the lengths of the first two sides is always higher than the length of the third side. In other terms, this theorem states that a straight line is always the shortest distance between any two places.

Using the triangle inequality theorem we have:

8 + 12 > x

x + 8 > 12

x + 12 > 8

20 > x

x > 4

x > -4

Therefore, the range of lengths Brett can use for the third piece of steel is 4 in. < x < 20 in.

The inequality x ≤ 3 indicates how many different bicycle outfits she can purchase.

She has $560 to spend at a bike shop on new accessories and clothing for riding.

For $425.05. she spends on a brand-new bicycle.

She spends $15.19 for each of four bicycle reflectors and $15.79 on a pair of cycling gloves.

She intends to use all or part of the remaining funds to purchase new bicycle clothing at $29.20 each.

The disparity that can be used to calculate how many garments she can purchase for her budget is as follows:

let

x = the number of garments

Therefore,

425.05 + 15.19(4) + 15.79 + 29.20x ≤ 560

425.05 + 60.76 + 15.79 + 29.20x ≤ 560

29.20x ≤ 560 - 425.05 - 60.76 - 15.79

Since an actual mosquito is about 1.6 cm, the scale factor of the diagram is equal to 2.

In Geometry, the scale factor of a geometric figure can be calculated by dividing the dimension of the image (new figure) by the dimension of the pre-image (actual figure):

Scale factor = Dimension of image (new figure)/Dimension of pre-image (actual figure)

Conversion:

1 cm = 10 mm

1.6 cm = 1.6 × 10 = 16 mm.

Substituting the given parameters into the scale factor formula, we have the following;

Step-by-step explanation:

To simplify the expression x^-2y(x^3y^5)^3, we need to perform the operations inside the parentheses first, using the exponent rule that (a^m)^n = a^(mn):

x^-2y(x^3y^5)^3 = x^-2y(x^(33)y^(53)) = x^-2y(x^9y^15)

Next, we can simplify the expression by multiplying the coefficients (numbers) and adding the exponents of x and y, using the product rule that x^mx^n = x^(m+n) and (xy)^m = x^my^m:

x^-2y(x^9y^15) = (1y/x^2)(x^9*y^15) = y^(15+1)x^(9-2) = y^16x^7

Therefore, the simplified form of x^-2y(x^3y^5)^3 is y^16*x^7.

Note that this expression is defined for all values of x and y except for x=0.

Answer:

The principal square root of a non-negative real number is the positive square root. For example, the principal square root of 25 is 5, since 5^2 = 25.

When solving radical polynomials, the principal square root is used because it is the most commonly used square root. In many contexts, including mathematical and scientific calculations, the principal square root is the default choice unless otherwise specified. Additionally, when working with radical expressions, we often simplify expressions by taking the principal square root, as it can help us to simplify calculations and express answers more clearly.

For the given function the intercepts are:

x-intercept: x = -4

y-intercept: y = 12.

Here we have a table that defines a function, and we want to find the intercepts of said function.

We can assume it is linear, then the slope of the function will be given by:

a = (9 - 3)/(-1 + 3) = 6/2 = 3

The linear function is like:

y = 3x + b

To find the value of b we can replace the values of the last point on the table, x = 2 and y = 18.

18 = 3*2 + b

18 = 6 + b

18 - 6 = b = 12

The linear function is:

y = 3x + 12

The x-intercept is the value of x when y = 0

0 = 3*x + 12
