Answer:

  (b) 156 miles

Step-by-step explanation:

In 2 hours, Marian will have driven 2×40 = 80 miles, and Ming will have driven 2×38 = 76 miles. The distance between them is ...

  80 mi + 76 mi = 156 mi

The drivers will be 156 miles apart in 2 hours.

Answer:

2/3

Step-by-step explanation:

2/3 = 14/21

4/7=12/21

Step-by-step explanation:

The vertex form of a parabola is given by

[tex]y = a(x - h)^2 + k[/tex]

where (h, k) are the coordinates of the vertex of the parabola. So we can write our parabola as

[tex]y = a(x - 3)^2 + 3[/tex]

We know that our curve goes through the point (2, -1) so we can solve for the constant a as follows:

[tex]-1 = a(2 - 3)^2 + 3 \Rightarrow -1 = a + 3[/tex]

or

[tex]a = -4[/tex]

Therefore, the vertex form of the equation for the parabola is

[tex]y = -4(x - 3)^2 + 3[/tex]

Answer:

-360

Step-by-step explanation:

hope this helps!

Answer:

-360

Step-by-step explanation:

[-1 3/5 × (-6)] × (-3 3/4) × 10

= [-8/5×-6] × -15/4×10

= 48/5×-15/4×10

= -360

Answer:The graph of y = f(x-2) is the graph of y = f(x) translated two units rightward.

So, since the point (9,2) lies on the graph of y = f(x), the point (11,2) lies on the graph of y = f(x-2).

[tex]70 + 7z \\ = 7(10 + z)[/tex]

7(10+z)

Answer:

y''=sec^3(x)*csc(x)+sec^2(x)*tan(x)-2cot(x)*csc(x)*sec(x)*tan(x)+cot^2(x)*csc(x)*sec(x)+csc^3(x)*sec(x)

Step-by-step explanation:

we are given y= csc x sec x

We use the rule for multiplying derivatives and the knowledge that the derivative of csc is -csc*cot and the derivative of sec is sec*tan to get

csc(x)*sec(x)*tan(x)+sec(x)*-csc(x)*cot(x)

which simplifies to

csc(x)*sec(x)*tan(x)-sec(x)*csc(x)*cot(x)

Using the same rules again (in tedium so they are not listed but can be inferred) we find the second derivative is

sec^3(x)*csc(x)+sec^2(x)*tan(x)-2cot(x)*csc(x)*sec(x)*tan(x)+cot^2(x)*csc(x)*sec(x)+csc^3(x)*sec(x)

Here is how your graph should look. Make sure to plot (0,-8) as your y-intercept.

Hope this can help ! :)

The rotation that the triangle DEF underwent is defined as follows:

180º around the origin.

A rotation is one example of transformation that a function can undergo, along with transformation, compression, stretching, dilation or reflection.

A rotation changes the inclination of the figure, and the rules for each rotation are given as follows:

In this problem, the coordinates are given as follows:

Hence the rule is:

(x,y) -> (-x, -y).

Meaning that a rotation of 180º around the origin was done.

Answer

-10

Step-by-step explanation:

-8w-7=9

add 7 to both sides

-8w=16

divide by negative 8 on both sides

w=-2

w-8=-10

On simplifying,

-8w - 7 = 9

-8w = 16

w = -2

then,

= w - 8

= -2 - 8

= -10.

Step-by-step explanation:

Answer:

t= -1/2 ,t=4

Step-by-step explanation:

2t^2- t -4 =0

2t^2 - 8t+t -4=0

(we have to find the factor here. I have used The Product Sum method of factorization)

2t( t-4) + 1( t-4)=0

(2t+1) (t-4)=0

t= -1/2 ,t=4
