Answer:

‐15−8= ‐15 + -8

‐15−(‐8)= ‐15 + 8

Step-by-step explanation:

‐15−8 = -23

‐15 + -8 = -23

‐15−(‐8) = -7

-15+8 = -7

Answer:

‐15−8= ‐15 + -8

‐15−(‐8)= ‐15 + 8

the answer would be (x+7)(x-7)

Answer:

(x+7)(x-7)

The factors are -7 and 7

Step-by-step explanation:

Given the function x²-49, to find the factors, we will factorise the expressed using the different of two square.

If a and b are two numbers, then based on difference of two square;

a²-b² = (a+b)(a-b)

Applying this to the function in question

x²-49

= x²-7²

= (x+7)(x-7)

The factors can be gotten by equating the function to zero according to factor theorem.

(x+7)(x-7) = 0

x+7 = 0 and x-7 = 0

x = -7 and 7

D = 6 in (divide it by two to get the radius) R = 3 in

Radius = 3 in

Formula:

SA = 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex]r²

Solution:

Answer:

B) The initial number of subscribers.

Step-by-step explanation:

The given equation is:

[tex]y=42000(0.96)^{t}[/tex]

[tex]y=42000(1-0.04)^{t}[/tex]

We can compare this equation with the general model of exponential growth/decay:

[tex]y=A(1-r)^{t}[/tex]

Here A represents the initial amount, r represents the rate of decay and t represents the time in years.

Comparing both equations, we can see that 42,000 represents the Initial Quantity which in this case is the initial number of subscribers.

So option B gives us the correct answer.

Step-by-step explanation:

We are given a right angled triangle.

Hypotenuse = c = [tex]\frac{25}{7}[/tex]

Base = a = 1

Now we are supposed to find the perpendicular i.e. b

So, we will use Pythagoras Theorem  :

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

[tex]c^2=b^2+a^2[/tex]

[tex](\frac{25}{7})^2=b^2+1^2[/tex]

[tex]\frac{625}{49}=b^2+1[/tex]

Answer:

50% and 50%, they are both the same!

When breeding a patchwork fish (Bb) with a fish that only has Blue Scales (BB), there is a 50% chance of having fish with red scales (Bb) and a 0% chance of having fish with patchwork scales (bb).

When breeding a patchwork fish (Bb) with a fish that only has Blue Scales (BB), the offspring will have a 50% chance of having red scales (Bb) and a 50% chance of having blue scales (BB). This is because the blue scales are dominant over the red scales, represented by the capital 'B', and the patchwork scales are recessive, represented by the lowercase 'b'.

To calculate the probability of having fish with red scales, we divide the number of offspring with red scales (Bb) by the total number of possible offspring, and then multiply by 100. So the probability is 50%.

To calculate the probability of having fish with patchwork scales, we divide the number of offspring with patchwork scales (bb) by the total number of possible offspring, and then multiply by 100. Since the fish that only has blue scales does not carry the patchwork gene, there will be no offspring with patchwork scales. Therefore, the probability is 0%.

Answer:

Linear

y = -30x + 100

Step-by-step explanation:

The table has a set of inputs with matching outputs. The behavior of the outputs will determine the type of function. The outputs appear to descend at a constant subtraction rate of -30 each time.

70 - 30 = 40

40 - 30 = 10

10 - 30 = -20

etc.

A constant addition or subtraction rate is a slope. Since the function has a slope, this is a linear function.

To write the function you'll need a slope and a y-intercept. Recall, the y-intercept is where x = 0. This is not in the table but can be found by reversing the process by adding 30 + 70 = 100.

Substitute m = -30 and b = 100 into y = mx+b for the equation.

y = -30x + 100

Answer:

90 monkeys

Step-by-step explanation:

If the circus has 40 lions (4*10) = 40

Lions would also multiply by 10 (9*10) = 90

Both sides must be multiplied by the same number to be consistent.

Check the picture below.

now, let's notice the triangle on the base.... is an isosceles, two sides are twins, and therefore, the two angles they make out are also twins, so, if the central angle is 100°, the other angles are each 80°/2, namely 40°, therefore, using the law of sines,

[tex]\bf \textit{Law of sines} \\\\ \cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \cfrac{sin(100^o)}{2.5}=\cfrac{sin(40^o)}{r}\implies r\cdot sin(100^o)=2.5\cdot sin(40^o) \\\\\\ r=\cfrac{2.5\cdot sin(40^o)}{sin(100^o)}\implies \boxed{r\approx 1.63}[/tex]

now, let's notice the shaded triangle, namely the one with 35°, is a right-triangle, namely one angle is 35°, another 90°, so the last one must be 55°.

the opposite side to the 35° is "r", which we know is about 1.63, so again, let's use the law of sines to find the side "h",

[tex]\bf \cfrac{r}{sin(35^o)}=\cfrac{h}{sin(55^o)}\implies r\cdot sin(55^o)=h\cdot sin(35^o) \\\\\\ \cfrac{r\cdot sin(55^o)}{sin(35^o)}=h\implies \cfrac{1.63\cdot sin(55^o)}{sin(35^o)}\approx h\implies \boxed{2.33\approx h} \\\\[-0.35em] ~\dotfill\\\\ \textit{volume of a circular cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r\approx 1.63\\ h\approx 2.33 \end{cases}\implies V\approx \cfrac{\pi (1.63)^2(2.33)}{3}\implies \blacktriangleright V\approx 6.48 \blacktriangleleft[/tex]

Answer:

Part A: Up 9

Part B: Up 6

Step-by-step explanation:

Part A: The graph appears to be a cosine graph since it starts at a peak on the y-axis. Normally a cosine graph starts at (0,1). This graph begins at (0,10). It has been shifted up y a translation by 9.

Part B: Each trig equation has a basic structure f(x) = a sin (x+b) + k where:

A vertical translation is a vertical shift and is represented by the value in k added outside of the function. In the equation f(x) = 2sin(θ + 120°) + 6, k = 6. The vertical translation is 6.

Answer: third option

Step-by-step explanation:

To solve the exercise you must apply the proccedure shown below:

- Find the value of irrational number given in the problem (By definition, an irrational number cannot be written as a simple fraction, where the numerator and the denominators are integer.

- Then the value in decimal number is the following:

[tex]\sqrt{115}=10.72[/tex]

- The number 10.72 is located between the integer 10 and the integer 11.

Step-by-step explanation:

2/3=10/15 (divide 15 by 3 to get 5, then multiply both numerator and denominator by 5 to set equivalent)

3/5=9/15

10/15 is greater than 9/15, so during the 1st week there were more boy campers

During the first week of a summer camp, there were more boy campers.

To determine during which week there were more boy campers, we need to compare the fractions of boys in each week. In the first week, 2 out of 3 campers were boys, which can be written as a fraction as 2/3. In the second week, 3 out of 5 campers were boys, which can be written as a fraction as 3/5. To compare these fractions, we need to find a common denominator. In this case, the lowest common denominator is 15, which is the total number of campers each week. Multiplying the numerator and denominator of each fraction by 5 and 3 respectively, we get 10/15 for the first week and 9/15 for the second week. Therefore, during the first week, there were more boy campers.

Answer: About 27.01

Step-by-step explanation: The way to find the diagonal is to multiply one side of the square by the sq. rt. of 2. First, we had to find one side of the square, which would be 76.4 divided by 4, then multiply that by the square root of 2.

76.4 / 4 = 19.1

19.1 x sq. rt. of 2 = 27.0114790413, or about 27.01
