Answer:

f(-2) = 1

Step-by-step explanation:

f(-2) means find the y value when x = -2

Going to x=-2 and going up until we hit the blue line

f(-2) = 1

Answer:

[tex]\Large \boxed{f(-2)=1}[/tex]

Step-by-step explanation:

For f(-2), the input of the function f(x) is -2.

The input is the x value.

[tex]x = -2[/tex]

The output is the value of y.

When x = -2 on the graph, y = 1.

Answer:

Step-by-step explanation:

Since ∆ ABC is a triangle the sum of it's angles add up to 180°

In order to find x we must first find [tex]\angle[/tex] AED

Let [tex]\angle[/tex] AED = E

To find [tex]\angle[/tex] AED add up all the angles in the triangle and equate it to 180°

That's

35 + 90 + E = 180

125 + E = 180

E = 180 - 125

E = 55°

E and x lie on a straight line

So we have

x + 55 = 180°

x = 180 - 55

Answer:

18) Area= 5*5/2=25/2=12.5 unit ^2

19) Area=AB^2V3/4=8a^2*V3/4=2V3a^2

Step-by-step explanation:

18. A(-3,0)

B(1,-3)

C(4,1)

AB=V(-3-1)^2+(0+3)^2=V16+9=V25=5

AC=V(-3-4)^2+(0-1)^2=V49+1=V50=5V2

BC=V(1-4)^2+(-3-1)^2=V9+16=V25=5

so AB=BC=5

and AC^2=AB^2+BC^2

so trg ABC is an isosceles right  angle triangle (<B=90)

Area= 5*5/2=25/2=12.5 unit ^2

19. A(a,a)

B(-a,-a)

C(-V3a, V3a)

AB=V(a+a)^2+(a+a)^2=V4a^2+4a^2=V8a^2

AC=V(a+V3a)^2+(a-V3)^2=Va^2+2a^2V3+3a^2+a^2-2a^2V3+3a^2=V8a^2

BC=V(-a+V3a)^2+(-a-V3a)^2=V8a^2

so AB=AC=BC

Area=AB^2V3/4=8a^2*V3/4=2V3a^2

Factors multiply to get a product. You can take this process in reverse.

As another example, the number 12 factors into 3*4, where 3 and 4 are the two factors. This idea applies to both numbers and variable expressions as well.

Answer: 5418.54 feet

Step-by-step explanation:

Given: Nadia started at 19.26 feet below sea level.

She climbed a total of 5,437.8 feet up from her initial position.

Since we take negative integers to show depth .

Here,  19.26 feet below sea level. means - 19.26 feet respective to sea level

So her altitude at the end of her climb above sea level = 5437.8-19.26 feet =

= 5418.54 feet

Hence, Nadia's altitude at the end of her climb was 5418.54 feet.

Answer:

AA Theorem

Step-by-step explanation:

In order to prove AB/AE = AC/AD, we need to prove that the triangles are similar. The AA Theorem says that if two triangles share two congruent angles, then the triangles are similar. The given states that ∠ABE ≅ ∠ACD, which means these two angles are congruent.

For the second angle, both triangles have the angle by point A. These angles can be written as ∠A ≅ ∠A. These angles are congruent because of the reflexive property.

Because we have proven these triangles to be simliar, we know the proportion AB/AE = AC/AD is correct because corresponding sides of similar triangles are proportional.

Step-by-step explanation:

Answer:

El tiempo que tardarán Lourdes y Rosabel en hacer el trabajo juntas es de 3,6 horas.

Step-by-step explanation:

Los parámetros dados son;

El tiempo que tarda Lourdes en leer las letras = 6 horas

El tiempo que le toma a Rosabel leer las letras = 9 horas

Sea la cantidad total de trabajo de oficina = X

Deje que el tiempo que ambos tienen que trabajar para hacer el trabajo = t

Por lo tanto;

La tasa de trabajo de Lourdes = X / 6

La tasa de trabajo de Rosabel = X / 9

X / 6 × t + X / 9 × t = X

t × (1/6 + 1/9) = 1

t × 5/18 = 1

t = 18/5 = 3,6 horas

Por lo tanto;

El tiempo que les llevará a Lourdes y Rosabel hacer el trabajo juntas = 3.6 horas.

Answer:

48 people

Step-by-step explanation:

It states that 12 people fit into a 5 x 5 ft² area.

Here, we are given the length and breath of the side, both 5 ft. And from that, we can estimate the area of the place.

Area of a square is gotten by multiplying both sides together, and thus

5 * 5 = 25 ft²

We are told 12 people fit into 25 ft². In order to get the number of people that fit a 10 x 10, we first need to calculate the area.

We already have the length and breadth to be 10 ft each, so

Area = 10 * 10 = 100 ft²

Now, we calculate.

If

12 people fit into 25 ft²

x people will fit into 100 ft²

If we cross multiply, we have

1200 = 25x

We then divide both sides by 25

x = 1200 / 25

x = 48

Therefore, 48 people will fit into a 10 x 10 ft area

Answer:

  9 3/4

Step-by-step explanation:

Strategy: first cancel the fraction part of the mixed number, then subtract the remaining fraction from the integer obtained.

10 1/2 - 3/4 = 10 1/2 - 1/2 - 1/4

= 10 -1/4

= 9 3/4

__

Strategy: turn the subtracted fraction into a whole number by adding 1/4 to both parts of the problem, then subtract the whole number.

10 1/2 - 3/4 = (10 1/2 +1/4) -(3/4 +1/4)

= 10 3/4 -1

= 9 3/4

_____

We assume that you know that 1/2 + 1/4 = 3/4, or 3/4 -1/2 = 1/4. If you need to, you can get there by using the equivalent: 1/2 = 2/4.

Answer:

Option 2

Step-by-step explanation:

Let's say that Phalicia opens her savings account one year (12 months) before she goes to college.

With Option 1, she would have saved 300 + 50 * 11 = $850. We do 50 * 11 and not 50 * 12 because she deposits $50 for 11 months, not 12.

With Option 2, she would have saved 5 * 3¹¹ = $885735. Note that we do 3¹¹ and not 3¹² because 5 is being tripled 11 times.

Obviously, she should choose Option 2 because she saves A LOT more money.

Additionally, we can notice that Option 1 is an example of an arithmetic sequence whereas Option 2 is an example of a geometric sequence. Their explicit formulas would be aₙ = 50n + 250 and aₙ = 5 * 3⁽ⁿ⁻¹⁾ respectively.

Angles 3, 6, and 5 and the answer. (put in form 3, 6, 5)

Step-by-step explanation:

Answer:

174 seconds.

Step-by-step explanation:

So there was a total of 7 songs.

And it took a total of 20 minutes and 18 seconds to play them all.

20 minutes and 18 seconds is the same as 20(60)+18=1218 seconds.

Thus, the average number of seconds per song was:

[tex]1218/7=174[/tex]

174 seconds,

or about 2 minutes and 54 seconds.

Answer:

A. △ABC and △JKL are similar.

Step-by-step explanation:

Since three angles of one triangle are congruent to three corresponding angles of the other triangle, the triangles are either congruent or similar. Since the side of one triangle is twice the length of the corresponding side of the other triangle, then the triangles are not congruent, but they are similar.

Step-by-step explanation:

Answer:

Step-by-step explanation:

In this problem we must first of all write the inequality that describes the problem.

Given that

1. you have a limit of $400

2. there is an initial fee of $50

3. monthly payment is $45

let the number of months be n

therefore

[tex]50+45n\leq 400\\\\45n\leq 400-50\\\\45n\leq350[/tex]

Divide both sides by 45 we have

[tex]n\leq \frac{350}{45} \\\\n=\frac{70}{9} \\\\n= 7.77\\\\[/tex]

[tex]\huge \boxed{x=-4}[/tex]

Step-by-step explanation:

[tex]\sf f(x)=-6x-3 \\\\\\ f(x)=21[/tex]

Applying substitution method and solving for the value of x.

[tex]\sf 21=-6x-3[/tex]

Adding 3 to both sides.

[tex]\sf 24=-6x[/tex]

Dividing both sides by -6.

[tex]\sf -4=x[/tex]

[tex]\huge\underline\bold\blue{ƛƝƧƜЄƦ}[/tex]

[tex]\large\boxed{f(x)=-129}[/tex]

Step-by-step explanation:

Given - f(x) = 21

Now we have to put the value in the given equation

f(x) = -6x-3

f(21) = -6(21) -3

= - 126 -3

= -129

Scale Factor to go from F to G = 3/4

Scale Factor to go from G to F = 4/3

===============================================

Explanation:

Note the sides labeled 4 and 3 are both opposite the angles that have two tickmarks. Therefore, these two sides correspond to one another.

Because of the similar triangles, the corresponding sides are in proportion. The scale factor is 3/4 meaning the smaller triangle has side lengths 3/4 as large compared to the larger triangle.

Put another way, we have a 25% reduction in the side lengths because 3/4 = 75% and 100% - 75% = 25%

So far, all of this applies when figure F is the preimage and G is the image. If we reverse things, then apply the reciprocal to 3/4 to get 4/3. Now G is the preimage and we go from smaller to larger.
