Answer:

The number of space shuttle launches the greatest in the year 1985 (C)

Step-by-step Explanation:

According to the graph given in the attachment, the no. of launches made in those years are:

1981: 2
1982: 3
1983: 4
1984: 5
1985: 9
1986: 6

The no. of launches was greatest in the year 1985 and the line graph touches the highest peak in 1985 $.$

Step-by-step explanation:

ok so as u know the angles of a triangle add up to 180.

So we will be using that for help.

S+R+T=180

12x+13x+12x-4+2-3=180

37x-5=180

37x=185

x=5

Now we will plug in the value for x to find each angle

S= 13(5)-4

=61

T=12(5)-3

=57

R=12(5)+2

=62

Hope this helped:)

Which description best compares the graphs given by the equations: x-5y=-5 5x-25y=75

yulyashka [42]

Considering the slopes of the given lines, they are parallel lines.

<h3>When are lines parallel, perpendicular or neither?</h3>

The slope, given by change in y divided by change in x, determines if the lines are parallel, perpendicular, or neither, as follows:

If they are equal, the lines are parallel.

If their multiplication is of -1, they are perpendicular.

Otherwise, they are neither.

The first line, in standard form, is given by:

5y = x + 5

y = 0.2x + 1.

The slope is of m = 0.2.

For the second line, we have that:

25y = 5x - 75

y = 0.2x - 3

The slope is of m = 0.2.

Same slope, hence the lines are parallel.

Susan invests $Z at the end of each year for seven years at an annual effective interest rate of 5%. The interest credited at th

aleksley [76]

Answer:

2.02955

Step-by-step explanation:

Given that:

Susan invests $Z as each year ends for seven years.

So we assume that Z = 1

Susan's accrued value comprises $7 invested each year at a 6 percent annual effective rate.

The cashflow interest:

The cashflow of Susan interest payments are:

Payments Time

0 1

0.05 2

2(0.05) 3

3(0.05) 4

4(0.05) 5

5(0.05) 6

6(0.05) 7

The accumulated value of this cash flow is:

$(0.05)I_{6\%} = (0.05) \dfrac{((1+0.06)_{6\%} - 6)}{0.06} \\ \\ \implies 1.1653$

So Susan accumulated values is:

X = 7 + 1.1653

X = 8.1653

Lori's accumulated value is $14, which she has set aside to plan her cash flow for interest.

The cashflow of Lori interest payments are;

Payments 0 0.025 2(0.025) 3(0.025) ......... 13(0.025)

Time 1 2 3 4 .......... 14

The accumulated value of cash flow is:

$(0.025 )(I)_{3\%} =(0.025) \dfrac{(1+0.03)_{3\%}-13}{0.03}\\ \\= 2.5719$

Now, Lori's accumulated value is:

Y = 14 + 2.5719

Y = 16.5719

Since; Susan value X = 8.1653

Lori's value Y = 16.5719

∴

$\dfrac{Y}{X}= \dfrac{16.5719}{8.1653}$

= 2.02955

Multiply. (3x - 2)(x + 5) A: 3x² + 17x - 7 B: 3x² + 17x - 10 C: 3x² + 13x - 10 D: 3x² + 6x - 7

Bess [88]

Answer:

The answer is C.

Step-by-step explanation:

You have to use Ditributive Law,

$a(m + n) = am + an$

So for this question :

$(3x - 2)(x + 5)$

$= 3x(x) + 3x(5) - 2(x) - 2(5)$

$= 3 {x}^{2} + 15x - 2x - 10$

$= 3 {x}^{2} + 13x - 10$
