If f(x) = -2x2 + x-5, what is f(3)?

Answer:

1

Step-by-step explanation:

(133)/7 - 18

133 ÷ 7 = 19

19 - 18 = 1

Answer: y = 1

Step-by-step explanation:

Well if x is 133 then the problem is y = (133/7) -18

and 133/7 is 19

so the problem is y = 19 - 18

and 19 - 18 is 1, so

y = 1

Answer:

Triangle DEF is congruent to triangle GHI.

You can use the process of elimination to get that. All three are not because when u look at their angles and their side. Triangle ABC is not like the others. And abc is not congruent to def because of the angles and the sides.

Answer:

1). The correct answer is  letter A)  

6). The correct answer is letetr D)

Step-by-step explanation:

Let be the equation of a sin function:

[tex]sin(x)=Asin(B(x+C))+D[/tex]

Where:

We can see from the image of the problem (6):

The amplitude is: A = 3 units

The vertical shift is: D = 6 units    

The phase shift is:  C = π

The period is : P = 4π = 2π/B then B = 1/2

Therefore the correct answer is letetr D)

[tex]sin(x)=3sin(0.5(x+\pi))+6[/tex]

In the problem (1) we have:

The amplitude is: A = -2 units

The vertical shift is: D = 6 units    

The phase shift is:  C = π/4

The value of B = 1

Then the correct answer is  letter A)

Step-by-step explanation:

Answer: Its a whole number. It is a composite number.

Step-by-step explanation:

Answer:

12.71in

step explanation:

The Length of an arc given is expressed as;

A = theta/360 * 2πr

10 = 45/360 * 2 * 3.14r

10 = 1/8 * 6.28r

Cross multiply

10 * 8 = 6.28r

80 = 6.28r

r = 80/6.28

r = 12.74in

Hence the radius is 12.71in

The correct equation for how much Madeline will have after [tex]8[/tex] years will be [tex]25000(1+0.095)^8[/tex]  which is in option [tex](b)[/tex].

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest

Amount [tex]=P(1+\frac{R}{100})^t[/tex]

We have,

Principal [tex]=\$25,000[/tex]

Rate[tex]=9.5\%[/tex]

Time [tex]=8[/tex] years

Now,

Using the above mentioned formula,

Amount [tex]=P(1+\frac{R}{100})^t[/tex]

              [tex]=25000(1+\frac{9.5}{100})^8[/tex]

Amount [tex]=25000(1+0.095)^8[/tex]

So, the equation for final amount  is [tex]25000(1+0.095)^8[/tex].

Hence, we can say that the correct equation for how much Madeline will have after [tex]8[/tex] years will be [tex]25000(1+0.095)^8[/tex] which is in option [tex](b)[/tex] .

Given:

Cost price of 40 shirts = Birr 220

Selling price of each shirt = Birr 72

To find:

The profit percentage.

Solution:

We have,

Cost price (CP) of 40 shirts = Birr 220

Selling price (SP) of each shirt = Birr 72

So, the selling price (SP) of 40 shirts is:

[tex]72\times 40=2880[/tex]

We need to find the profit percentage.

[tex]\text{Profit percentage}=\dfrac{SP-CP}{CP}\times 100[/tex]

[tex]\text{Profit percentage}=\dfrac{2880-220}{220}\times 100[/tex]

[tex]\text{Profit percentage}=\dfrac{2660}{220}\times 100[/tex]

[tex]\text{Profit percentage}=1209.09\%[/tex]

Therefore, the profit percentage is 1209.09%.

Answer:

The new average is 134/10, or 13.4 years.

Step-by-step explanation:

a + b + c + d + e + f + g + h + i + j

------------------------------------------------ = 13.5    (the original average)

                          10

15 years is 1.5 year older than the 13.5 average and 11 years is 2.5 younger than that.  The net change is 1.5 - 2.5, or -1.  The number of players remains the same:  10.  We subtract 1 from the sum of the player ages and divide the result by 10:

a + b + c + d + e + f + g + h + i + j - 1

---------------------------------------------------    = 13.4    (the new average)

                          10

Note that the sum of the original 10 ages is (10)(13.5), or 135, which becomes 134 after the 15-year-old joined the team and the 11 year old quit.  The new

average is 134/10, or 13.4 years.

Given:

The scale of a map is [tex]\dfrac{3}{4}\ in=80\ miles[/tex].

The distance between two buildings is 60 miles.

To find:

The distance between the given building on the map.

Solution:

We have,

[tex]\dfrac{3}{4}\ in=80\ miles[/tex]

It means, 80 miles in real life = [tex]\dfrac{3}{4}\ in[/tex] on the map.

1 mile in real life = [tex]\dfrac{3}{4\times 80}\ in[/tex] on the map.

60 mile in real life = [tex]\dfrac{3\times 60}{4\times 80}\ in[/tex] on the map.

                              = [tex]\dfrac{180}{320}\ in[/tex] on the map.

                              = [tex]\dfrac{9}{16}\ in[/tex] on the map.

Therefore, the buildings are [tex]\dfrac{9}{16}\ in[/tex] apart on the map.
