Answer:

A triangle with angles less than 90°

Step-by-step explanation:

An acute triangle is a triangle where all its interior angles are less than 90 degrees, distinguishing it from other types of triangles.

In mathematics, an acute triangle is a type of triangle where all three of its interior angles are less than 90 degrees. This is what distinguishes it from other types of triangles such as right triangles, which have one angle of exactly 90 degrees, or obtuse triangles, where one angle is larger than 90 degrees. For example, a triangle with angles of 30, 60, and 90 degrees would be considered an acute triangle because all the angles are less than 90 degrees.

Answer:

the 1.04 represents the increase in the house value each year, which is 4%

Answer:

The correct option is 3.

Step-by-step explanation:

The general exponential growth model is

[tex]y=a(1+r)^x[/tex]                .... (1)

where, a is the initial value, r is growth rate per period and x is number of periods. Here (1+r) is growth factor.

The given function is

[tex]f(x)=242,000(1.04)^x[/tex]

It can be written as

[tex]f(x)=242,000(1+0.04)^x[/tex]       .... (2)

From (1) and (2) we get

[tex]r=0.04=4\%[/tex]

In the given function 1.04 is growth factor. It means it represents increase in the value of the house per year which is 4%.

Therefore the correct option is 3.

Answer:

3080+d > = 3300

Step-by-step explanation:

The first question to ask is how much money do they need in the fund?

They need the shipment costs plus the future shipment costs

2800+500 = 3300

They have 3080

Let d = how much they need to deposit

How much they have plus how much they need to deposit must be greater than or equal to how much they need.

3080+d > = 3300

Winston drove 89 miles in the morning and 159 miles in the afternoon.

Let's assume that Winston drove x miles in the morning. Since he drove 70 fewer miles in the morning than he did in the afternoon, he drove (x + 70) miles in the afternoon.

According to the question, he can drive a total of 248 miles in a day. So, we can write the equation: x + (x + 70) = 248

Simplifying the equation, we get: 2x + 70 = 248

Subtracting 70 from both sides, we have: 2x = 178

Finally, dividing both sides by 2, we find: x = 89

Therefore, Winston drove 89 miles in the morning and (x + 70) = 89 + 70 = 159 miles in the afternoon.

Why do interest rates on loans tend to be lower in a weak economy than in a strong one?

The interest rates on loans tend to be lower in a weak economy than in a strong one because in a weak economy there is less demand for credit so the rates are lesser. In a stronger economy, the credit market demand is higher so as the demand increases the rate also increases.

Answer:

21.5 km

Step-by-step explanation:

We have to find the distance  between two boat

We are given that

AC=2.1 km

BC=3.5 km

We have to find BC

The angle between two boat =110 degrees

Using cosine law

BC=[tex]\sqrt{(2.1)^2+(3.5)^2-2\cdot(2.1)\cdot(3.5)cos 110}[/tex]

BC=[tex]\sqrt{4.41+12.25+ 2\cdot2.1\times3.5cos 70[/tex]

BC=[tex]\sqrt{4.41+12.25+9.3051}[/tex]

BC=21.507 km

Hence, the distance between two boat is 21.5 km

The distance between the two boats can be determined using the law of cosines. Inserting the provided values into the formula yields a distance of approximately 3.9 kilometers.

To solve this problem, we can apply the law of cosines, which states that c² = a² + b² - 2ab(cos Θ), where a and b are lengths of two sides of a triangle, c is the length of the third side, and Θ is the angle between sides a and b. Let's consider our light house worker as a starting point. The boat at 2.1 km south constitutes one side of the triangle (a = 2.1 km). The other boat, at 3.5 km 70° east of north, constitutes the second side (b = 3.5 km). The angle Θ between side a and side b is 70°. Therefore, the distance between the two boats (c) can be calculated as follows:

c² = a² + b² - 2ab(cos Θ) = (2.1 km)² + (3.5 km)² - 2 *(2.1 km)*(3.5 km) cos(70°)

Computing the above gives a distance of approximately 3.9 km.

Answer: I agree with Sauske. Sorry If I'm saying your name wrong.

Step-by-step explanation:

Answer:

l = 2.5 feet

Step-by-step explanation:

A = lb

8.5 = l * 3 2/5

8.5 = l * 3.4

l = 8.5 / 3.4

l = 2.5 feet (Always remember to put the units, otherwise you may not get points.)

Please give a rating and a thanks.

Thank you.

Answer:

l = 2 1/2 ft

Step-by-step explanation:

Area is given by the formula

A = l*w

We know the area is 8 1/2  

Changing this to an improper fraction  8 1/2 = (2*8 +1)/2 = 17/2

The width is 3 2/5  as an improper fraction  = (5*3+2)/5 = 17/5

A = l*w

17/2 = l* 17/5

Multiply each side by 5/17

17/2 * 5/17 = l* 17/5 * 5/17

5/2 = l

Answer:

x = 10

Step-by-step explanation:

the area of a square = s² ( s is the side length )

s² = (4x + 3)² ( take the square root of both sides )

s = [tex]\sqrt{(4x+3)^2}[/tex] = 4x + 3

perimeter = 4s = 172, that is

4(4x + 3) = 172 ( distribute left side )

16x + 12 = 172 ( subtract 12 from both sides )

16x = 160 ( divide both sides by 16 )

x = 10

Answer:

(x - 2)² + (y + 8)² = 121

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (2, - 8) and r = 11, hence

(x - 2)² + (y + 8)² = 121

The equation [tex]\((x-2)^2 + (y + 8)^2 = 121\)[/tex] represents a circle with a center at (2, -8) and a radius of 11. This is derived from the general circle equation [tex]\((x - h)^2 + (y - k)^2 = r^2\).[/tex]

The correct equation representing a circle with a center at (2, -8) and a radius of 11 is option (b) [tex]\((x-2)^2 + (y + 8)^2 = 121\)[/tex].

The general equation of a circle is [tex]\((x - h)^2 + (y - k)^2 = r^2\)[/tex], where (h, k) is the center and r is the radius.

In option (b), [tex]\((x-2)^2 + (y + 8)^2 = 121\)[/tex], the values match the given center (2, -8) and radius of 11. The squared terms with (x-2) and (y+8) are in the correct form, and the radius squared [tex](\(11^2 = 121\))[/tex] is on the right side.

Options (a), (c), and (d) do not represent the given circle because they have incorrect signs, centers, or radius values. Therefore, the correct equation is option (b).

Step-by-step explanation:

Equations may have exactly one solution, uncountable solutions or even no possible solution when the solution is a contradiction and this solution is never true.

1) [tex]\frac{1}{2}y+\frac{32}{10}y=20[/tex] One solution Let's prove it by solving it:

[tex]\frac{1}{2}y+\frac{32}{10}y=20\Rightarrow \frac{37}{10}y=20\Rightarrow 10*\frac{37}{10}y=20*10\\37y=200\Rightarrow \frac{37}{37}y=\frac{200}{37}\Rightarrow y=\frac{200}{37}\Rightarrow S=\left \{ \frac{200}{37} \right \}[/tex]

2)[tex]\frac{15}{2}+2z-\frac{1}{4}=4z+\frac{29}{4}-2z[/tex] Infinite Number of Solutions because infinitely many solutions satisfies for z.

[tex]\frac{15}{2}+2z-\frac{1}{4}=4z+\frac{29}{4}-2z\\\frac{29}{4}+2z=\frac{29}{4}+2z[/tex]

3) [tex]3z+2.5=3.2+3z[/tex] No solution. There's no way to add 2.5 to 3z and have the same amount as adding 3.2 to 3z. This is contradiction. This is a false equality.

4) [tex]1.1+\frac{3}{4}x+2=3.1+\frac{3}{4}x[/tex] Infinitely many solutions. This equation has infinitely many solutions since the left side is equal to the right side, any value plugged in x may result in many solutions.

5) [tex]4.5r=3.2+4.5r[/tex] No solution Similarly, again. There's no way of adding 3.2 to 4.5r being equal to 4.5r. Another contradiction. This is a false equality.

6) [tex]2x+4=3x+\frac{1}{2}[/tex] One solution

[tex]2x+4=3x+\frac{1}{2}\\2x+4-2x=3x+\frac{1}{2}-2x\\4=x+\frac{1}{2}\\4-\frac{1}{2}=x\Rightarrow x=\frac{7}{2}\Rightarrow S=\left \{ \frac{7}{2} \right \}[/tex]

Answer:

y = 15x + 85

Step-by-step explanation:

Let:

x = amount of months ; y = total amount

The constant is 85, meaning that this number will not change (for he would have at least 85 no matter how much time has passed).

15 is next to a variable, for depending on the amount of time passed, you will add a certain amount of "15" to the answer.

y is your total, and is also a variable, because it also depends on the amount of time that passes.

Answer:

+$65

Step-by-step explanation:

We are asked to determine the integer that represents saving $65.

We know that savings represent a positive number. Savings stands for the amount saved by a person.

We know that loss, withdraw and spend represent negative quantities, while the savings, profit  and deposit represent positive quantities, therefore, saving of $65 would be +$65.

For this case, we have to:

By definition, we know:

The domain of [tex]f (x) = \sqrt [3] {x}[/tex] is given by all real numbers.

Adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. In the same way, its domain will be given by the real numbers, independently of the sign of the term inside the root. Thus, it will always be defined.

So, we have:

[tex]y = \sqrt [3] {x-2}[/tex] with[tex]x = 0[/tex]: [tex]y = \sqrt [3] {- 2}[/tex] is defined.

[tex]y = \sqrt [3] {x+2}[/tex]with [tex]x = 0:\ y = \sqrt [3] {2}[/tex] is also defined.

[tex]f (x) = \sqrt {x}[/tex]has a domain from 0 to ∞.

Adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. For it to be defined, the term within the root must be positive.

Thus, we observe that:

[tex]y = \sqrt {x-2}[/tex] is not defined, the term inside the root is negative when[tex]x = 0[/tex].

While [tex]y = \sqrt {x+2}[/tex] if it is defined for [tex]x = 0[/tex].

Answer:

Step-by-step explanation:

Answer:

8 cm.

Step-by-step explanation:

We have been given that an ice cream cone that is 4 cm across the top is topped with a single scoop of ice cream (spherical) that is 4 cm in diameter.

To find the minimum height of cone we will use volume of cone formula and volume of sphere as we are told that when the ice cream melts, the ice cream does not overflow out of the cone. This means that volume of sphere will be equal to volume of cone.

[tex]\text{Volume of cone}=\frac{1}{3} \pi r^2h[/tex]

[tex]\text{Volume of sphere}=\frac{4}{3} \pi r^3[/tex]

Since diameter of both cone and sphere is 4 cm, so radius will be half the diameter, that is 2 cm.

Let us substitute r=2 in both equations and equate the volumes of cone and sphere to find the height of cone.

[tex]\frac{4}{3} \pi\times 2^3=\frac{1}{3} \pi\times 2^2\times h[/tex]

[tex]\frac{4}{3} \pi\times 8=\frac{1}{3} \pi\times 4\times h[/tex]

Multiply both sides of equation by 3.

[tex]3\times \frac{4}{3} \pi\times 8=3\times \frac{1}{3} \pi\times 4\times h[/tex]

[tex]4 \pi\times 8= \pi\times 4\times h[/tex]

[tex]32 \pi= 4\pi\times h[/tex]

[tex]h=\frac{32 \pi}{4\pi}[/tex]

[tex]h=8[/tex]

Therefore, the minimum height of cone must be 8 cm.

Answer: hope this helps. it's 130.

Answer:

Length = 6 cm and width = 4 cm.

Step-by-step explanation:

Let the width be x, then the length is x + 2 cm and its area = x(x + 2).

The new width and length are x + 4 and x + 6, and the new area is

(x + 4)(x + 6).

So we have the equation:-

(x + 6)(x + 4) = x(x + 2) + 56

x^2 + 10x + 24 = x^2 + 2x + 56

10x - 2x = 56 - 24

8x = 32

x = 4 cm = width

and length = 4 + 2 = 6 cm

Answer:

$9,936.47

Step-by-step explanation:

Similarly to the other problem I helped you with we have:

[tex]A_{final}=A_{initial}(1+r)^t[/tex]

Where A is amount, r is rate and t is time.

In this case A=12000, r=9%=0.09 and 9% in decimals is 0.09 (9÷100=0.09), and t=7 since 2025 -2018 = 7 years. So how much is this investment worth in 7 years? Let's plug those values in and we obtain:

[tex]A_{final}=12000(1+0.09)^7=12000(1.09)^7=21936.47[/tex]

So the investment will be worth $21,936.47.  Now we must calculate how much more will this precious mineral be worth so we get the difference of the final amount and the initial amount the mineral was worth and so:

[tex]A_{final}-A_{initial}=21936.47-12000=9936.47[/tex]

And so the mineral will be worth $9,936.47 more than it originally was worth after 7 years.
