What value is equivalent to 8 · 9 − 2 · 5?

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange - 3x + 4y = 5 into this form

Add 3x to both sides

4y = 3x + 5 ( divide all terms by 4 )

y = [tex]\frac{3}{4}[/tex] x + [tex]\frac{5}{4}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{3}{4}[/tex]

• Parallel lines have equal slopes, thus

y = [tex]\frac{3}{4}[/tex] x + c ← is the partial equation of the parallel line

To find c substitute (2. 1) into the partial equation

1 = [tex]\frac{3}{2}[/tex] + c ⇒ c = - [tex]\frac{1}{2}[/tex]

y = [tex]\frac{3}{4}[/tex] x - [tex]\frac{1}{2}[/tex] ← equation of parallel line

g(x) =f(x) +3

given f(x) =3x

i.e. g(x) =3x+3

For F(x) to be same as g(x)

3 must be added to f(x)

i.e. h(x) =3x+3

->h(x)= 3x +3(1)

-> h(x) = f(x) +f(1)

-> h(x) =f(x+1)

Hence Option (a) is your answer...

Answer:

A) h(x) =  f(x +1).

Step-by-step explanation:

Given : f(x) = 3x and g(x) = 3x + 3.

To find : Which transformation of f(x) will produce the same graph as g(x).

Solution : We have given

f(x) = 3x

For x = 1.

f(1) = 3 (1)

f(x) = 3.

Plug the value of f(x) =3x and f(1) = 3 in g(x).

g(x) = 3x + 3.

g(x) = f(x) + f(1).

We can write  f(x) + f(1) = f(x +1).

g(x) = f(x +1)

h(x) = f(x +1)

So, it is a new function produce the same graph as g(x).

h(x) =  f(x +1).

Therefore, A) h(x) =  f(x +1).

Answer:remove the radical and try not to simplify

Step-by-step explanation:

Hey there! :)

-7x - 4y = -8

To find the slope, we must turn this equation into slope-intercept form.

Slope-intercept form is : y=mx+b ; where m=slope, b=y-intercept

To get here, we must isolate y by adding 7x to both sides of our original equation.

-7x + 7x - 4y = 7x - 8

Simplify!

-4y = 7x - 8

Then, divide both sides by -4.

-4y ÷ -4y = (7x - 8) ÷ -4y

Simplify!

y = -7/4x + 2

Congrats, we got y isolated! Now, review the slope-intercept form equation to figure out what our slope & y-intercept are.

After reviewing our slope intercept form equation, we can come to the conclusion that -7/4 is our slope because it's in the "m" value slot, and 2 is our y-intercept because it's in the "b" spot.

So, our answer is :

Slope = -7/4

Y-intercept = 2

You can use the Pythagorean theorem a squared plus b squared equals c squared

the set of numbers that does NOT form a right triangle is option D: 27, 35, 46.

To determine whether a set of numbers forms a right triangle, we need to check if the Pythagorean theorem holds true for them. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Let's calculate the squares of the sides for each option:

A. 14, 48, 50

14² + 48² = 196 + 2304 = 2500

50² = 2500

B. 15, 20, 25

15² + 20² = 225 + 400 = 625

25² = 625

C. 21, 28, 35

21² + 28² = 441 + 784 = 1225

35² = 1225

D. 27, 35, 46

27² + 35² = 729 + 1225 = 1954

46² = 2116

Now, let's compare the squares of the two smaller sides with the square of the largest side for each option:

A. 2500 = 2500 (Forms a right triangle)

B. 625 = 625 (Forms a right triangle)

C. 1225 = 1225 (Forms a right triangle)

D. 1954 ≠ 2116 (Does NOT form a right triangle)

So, the set of numbers that does NOT form a right triangle is option D: 27, 35, 46.

Answer:

b = √c²-a²

Step-by-step explanation:

b² = c² - a²

b = √c²-a²

The Pythagorean theorem, denoted as a² + b² = c², can be rearranged as b = √(c² - a²) to solve for one of the sides of a right triangle. Once the lengths for a and c are known, they can be substituted into the formula to find the length of b.

The Pythagorean theorem, a key geometric principle, can be used to solve for one of the sides in a right triangle given the lengths of the other two. Usually, it's denoted as a² + b² = c², where a and b are the lengths of the triangle's legs, and c is the length of the hypotenuse. In the question, you want to solve for b.

First, let's isolate b in the formula. Rewrite the formula as b² = c² - a². To find the length of b, take the square root of both sides, resulting in b = √(c² - a²).

Now, once you have the values for a and c, you can substitute them into the formula to find b. This application of the Pythagorean theorem can be very useful in various situations where you have a right triangle, and you know the lengths of two of its sides but need to find the length of the third side.

Answer: Approximately 3799 or 3800 cubic inches

Step-by-step explanation:

To find the volume of a cylinder I imagine I'm first finding the area of one of the circular "bases" (top or bottom) using the formula: Area = pi x radius squared. Once you have the area of a base, imagine you "stack" as many of them on top of each other until you get to the given height (here, it's 10 in. tall).

9 + 15 = 24

To find the total number of cookies sold for the week, add up the number of cookies sold each day. The total is 2200. When considering both types of cookies, the website will have sold 24 cookies in total.

To find the total number of cookies sold for the whole week, we will add up the number of cookies sold on each day. Using the given numbers, the total number of cookies sold is

= 500 + 300 + 400 + 800 + 200 = 2200.

For the second part, we need to find the total number of cookies sold when considering both gooey chocolate chip cookies and peanut butter blossoms. We add up the number of each type of cookie: 9 + 15 = 24.

since height to base ratio is tan73 so approx ratio is 3.27

The approximate height-to-base ratio is 3.27: 1

Given,

A 20-foot ladder is set up against a building so that the ladder makes an angle of 73° with the ground.

The height, h, is the vertical distance from the top of the ladder to the base of the building.

The base, b, is the horizontal distance from the bottom of the ladder to the base of the building.

We need to find what is the approximate height-to-base ratio.

Sin Ф = Perpendicular / Hypotenuse

Cos Ф = Base / Hypotenuse

Tan Ф = Perpendicular / Base

Find the height in the figure.

Sin 73 = h / 20 ft

Sin 73 = 0.9563

So,

0.9563 = h / 20 ft

h = 0.9563 x 20 ft

h = 19.126 ft

Find the base in the figure.

Cos 73 = b / 20 ft

Cos 73 = 0.2924

0.2924 = b / 20 ft

b = 0.2924 x 20 ft

b = 5.848 ft

Find the approximate height-to-base ratio.

= h : b

= 19.126 : 5.848

= 3.27 : 1

Thus the approximate height-to-base ratio is 3.27: 1

The information in the diagram is enough to determine that △LMN ~ △PON using a rotation about point N and a dilation because one pair of congruent corresponding angles is sufficient to determine similar triangles.

In order to determine that two triangles are similar, you need to establish that their corresponding angles are congruent, and their corresponding sides are in proportion.

In the given scenario, you have △LMN and △PON. The key information is that ∠MNL and ∠ONP are congruent angles. This means that one pair of corresponding angles is equal.

According to the Angle-Angle (AA) similarity theorem, if you have two pairs of corresponding angles that are congruent, the triangles are similar. In this case, you have one pair of congruent corresponding angles, ∠MNL ≅ ∠ONP, which is sufficient to determine that △LMN ~ △PON.

The statement "because one pair of congruent corresponding angles is sufficient to determine similar triangles" is the correct explanation for why △LMN is similar to △PON using a rotation about point N and a dilation.

Step-by-step explanation:

If point (3.4, 1.2) lies on a circle, the distance between this point and the center (1, -2) is equal to the radius r = 4.

The formula of a distance between two points:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substitute:

[tex]d=\sqrt{(1-3.4)^2+(-2-1.2)^2}=\sqrt{(-2.4)^2+(-3.2)^2}\\\\=\sqrt{5.76+10.24}=\sqrt{16}=4=r[/tex]

The point (3.4, 1.2) lies on the circle, and distance between the two is 4 units.

To determine whether the point (3.4, 1.2) lies on the circle with a center at (1, -2) and a radius of 4, we can use the distance formula to calculate the distance between the center of the circle and the given point. If this distance is equal to the radius of the circle, then the point lies on the circle; otherwise, it does not.

The distance formula between two points[tex]\((x_1, y_1)\)[/tex] and [tex]\((x_2, y_2)\)[/tex] is given by:

[tex]\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \][/tex]

Let's calculate the distance between the center of the circle (1, -2) and the given point (3.4, 1.2):

[tex]\[ d = \sqrt{(3.4 - 1)^2 + (1.2 - (-2))^2} \]\[ d = \sqrt{(3.4 - 1)^2 + (1.2 + 2)^2} \]\[ d = \sqrt{(2.4)^2 + (3.2)^2} \]\[ d = \sqrt{5.76 + 10.24} \]\[ d = \sqrt{16} \]\[ d = 4 \][/tex]

The calculated distance between the center of the circle and the given point is equal to the radius of the circle, which is 4 units.

where  

I is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have

where

a is the initial value

b is the base of the exponent.

we have

Initial population of ants is 300----> initial value is a=300

The number of ants increases 1.5% per month.

Since it will increases by 1.5% every month, it will become: 100%+1.5%=101.5%

the base is 101.5%, b=1.015

Answer: Third option

[tex]u = -\frac{5\sqrt{29}}{29}i -\frac{2\sqrt{29}}{29}j[/tex]

Step-by-step explanation:

A unit vector [tex]u[/tex] is a vector that has magnitude 1.

To find a unit vector in the direction of the vector v we must first calculate the magnitude of v and then divide the vector v by its magnitude

The vector v is:

v = -5i - 2j

The magnitude of the vector is:

[tex]| v | =\sqrt{(-5)^2 +(-2)^2}\\\\|v|= \sqrt{29}[/tex]

Now we divide the vector v by its magnitude

[tex]u = \frac{1}{\sqrt{29}}v[/tex]

[tex]u = -\frac{5}{\sqrt{29}}i -\frac{2}{\sqrt{29}}j[/tex]

Simplifying we have to

[tex]u = -\frac{5\sqrt{29}}{29}i -\frac{2\sqrt{29}}{29}j[/tex]

Final answer:

To find the unit vector u in the direction of v = -5i - 2j, compute the magnitude of v and then divide each component of v by this magnitude. The result is u = (-5/√(29))i + (-2/√(29))j.

Explanation:

The question involves finding a unit vector in the direction of a given vector v = -5i - 2j. A unit vector is a vector with a magnitude of 1 that points in the direction of a given vector. To find the unit vector u in the direction of v, we first calculate the magnitude of v and then divide each component of v by its magnitude.

Upon calculating, the magnitude of v is sqrt(29), so the unit vector is u = (-5/√(29))i + (-2/√(29))j.

That's just a matter of calculating the areas of all triangles, rectangles and hexagon of the assembly.

Triangles: base: 4 cm, height: 5 cm, quantity: 6

A = (b * h) / 2 = (4 * 5) / 2 = 10 sq cm

AT = 6 * V = 6 * 10 = 60 sq cm

Rectangles: base: 4 cm, height: 6 cm, quantity: 6

A = b * h = 4 * 6 = 24 sq cm

AR = 6 * V = 6 * 24 = 144 sq cm

Hexagon: side: 4 cm, quantity: 1

Since it's a regular hexagon and we know its side length...

AH =  (3√3 * s²)/2 = (3√3 * 16)/2 = 24√3 = 41.57 sq cm

Then we add everything together:

A = AT + AR + AH

A = 60 + 144 + 41.57 = 245.57 sq cm

Rounded answer: 246 sq cm

Answer:

246 cm²

Step-by-step explanation:

The composite space figure consists of:

The surface area is the sum of all the areas of each figure.

Area of a hexagon = ½√(27) s²

Area of a rectangle = wl

Area of a triangle = ½ bh

So the total area is:

A = ½ √(27) (4)² + 6(4×6) + 6(½×4×5)

A = 8√(27) + 204

A ≈ 246 cm²
