Answer:

the fourth choice.

Step-by-step explanation:

it has to be a parabola that crosses the x axis at positive 2 and negative 3

The larger of the triangle’s two acute angles is 65 degrees

Given the expression

sin(x+4) = cos(3x + 2)

Since sin theta = cos(90 - theta), hence;

cos(90 - (x+4)) = cos(3x +2)

cos(86 - x) = cos (3x+2)

Cancel out the cosine functions to have:

86 - x = 3x + 2

-4x = -84

x = 21

Substitute x = 21 into the expression

sin(x+4) = Sin25 =

Hence the larger of the triangle’s two acute angles is 65 degrees

Answer:

$244.51

Step-by-step explanation:

Credit card payment =$5390

After paying $2300 from savings account,

Remaining payment left     = 5390-2300 = $3090

APR = 16.5% or 0.165

Time (t) = 14 months = 14/12 years

Using credit card payment calculator,

Monthly payment = $244.15

Hence, minimum monthly payment to be made to pay off the whole debt in 14 months = $244.15

Answer:

[tex]x=7, x=-3[/tex]

Step-by-step explanation:

Bring the 21 on the LHS:

[tex]x^2-4x-21=0[/tex]

At this point we need to find two numbers whose product is -21, and whose sum is -4.

From the product we can tell that one has to be positive, and one is negative.

From the sum, we can tell that the greater of the two is negative.

At this point we look at the factors of 21: 1,3,7,21.

In particular, 3 and -7 added togheter do -4, which is what we need. At this point we can factor the trinomial as

[tex](x-7)(x+3)=0[/tex]

Considering that a product is zero if any of the factors is zero, it's:[tex]x-7=0 \rightarrow x=7\\x+3=0 \rightarrow x=-3[/tex]

Step-by-step explanation:

Suppose adult tickets are x ticket

Student tickets are 1216 - x ticket

x(5) + (1216 - x)(1) = 2596

5x + 1216 - x = 2596

4x = 2596 - 1216

4x = 1380

x = 345

Adult tickets have 345 tickets

and student tickets have 1216 - 345 = 871 tickets.

Answer:

Step-by-step explanation:

We are told to model the number of students in the club. That is the dependent variable, so we will assign 'y' to that quantity. The number of students in the club is a function of the number of weeks since it was formed, so we can assign 'x' to that independent variable.

The initial value of y is 6, and it increases by 3x (that is, 3 students each week). The model of the number of homework club students can be ...

  y = 3x +6

The perimeter of the face PQR is 84 cm.

The perimeter of an object is the sum of the lengths of the sides of the object.

Given that, there are two similar triangular prisms. Figure 2 is similar to figure 1 by a scale factor of 4.

We know that, the ratio of the perimeters of similar objects is equal to their scale factor.

Therefore,

P(ABC) / P(PQR) = 1/4

21 / P(PQR) = 1/4

P(PQR) = 84

Hence, the perimeter of the face PQR is 84 cm.

Answer:

3.5 miles per hour of speed

Step-by-step explanation:

Given:

To find:

0.875                      15

             x                           60

Answer: Lien walked 3.5 miles per hour of speed.

Step-by-step explanation:

Distance Lien walked = 7/8 of a mile = 0.875 miles

Time of walking = 1/4 of an hour = 15 minutes

Distance in miles     Time in minutes

          0.875                      15

             x                           60

Calculations:

15x = 0.875 * 60

15x = 52.5

x = 52.5/15

x = 3.5

Answer:

1$

Step-by-step explanation:

Her total amount is 40$

She then buys the tires(tires = 21$) so she bought that subtract 21$ from 40$ 40$ - 21$=19$

She next wanted to buy a bell so she did the bell was 5$ so subtract 5$ from 19$ 19$-5$=14$ left

So remember she has 14$ left and she is buying a basket which is 13$ so her buying the basket is remaining her with 1$ because basket is 13$ and she has 14$ so what is 14$-13$ it is 1$  and there's your answer.

Answer:

I'm not so sure but it's 90°

Step-by-step explanation:

the line is

20x - 17y = 15

I am not sure what your teacher uses as "standard form".

the works is split between "point-slope" and "slope-intercept" form as "standard".

I usually pick "slope-intercept" :

y = ax + b

with a being the slope and b being the y-intercept.

in any case, we can find the x-intercept without bringing the line equation to one of these forms.

because x-intercept simply means that y = 0.

and for y=0 the original equation is then

20x - 17×0 = 15

20x = 15

x = 15/20 = 3/4

How to find input and output from the co-ordinates on the graph?

Here the co-ordinate having x=2 is

So the output is 0

Every pair have ( x , y ) which means x is input and y is output .

Here , input is 2 (x)

then , let output be y ( indicate with 0 )

So , the co- ordinates are ( x , y ) = ( 2 , 0 ) .
