Answer:

We have: I = P × R × T / 100

Here, I = 980

P = 7000

T = 8

Substitute their values into the expression:

980 = 7000 × R × 8 / 100

R = 980 × 100 / 7000 × 8

R = 98000 / 56000

R = 1.75%

In short, Your Answer would be 1.75%

What is the vertex of y=x^2+4x+3

AnnyKZ [126]

Answer:

(-2, -1)

Step-by-step explanation:

This is a quadratic equation in standard form, and a = 1, b = 4 and c = 3.

The x-coordinate of the vertex is given by the formula

-b -4

x = --------- which here has the numerical value x = -------- = -2

2a 2

Finally, we evaluate y=x^2+4x+3 at x = -2 to find the y-coordinate of the vertex:

y = (-2)^2 + 4(-2) + 3 = -1

The vertex is at (-2, -1).

Jordan estimated that his paper airplane would fly 42 feet. It actually traveled 50 feet. What was the percent error?

topjm [15]

$\huge \mathcal{ Answer࿐}$

Error (e) = 50 - 42 = 8 feet

assumed value (a) = 42 feet

$\boxed{ \mathrm{ \% \: error = \dfrac{error}{assumed \: value} \times 100}}$

$\mathrm{ \% \: error =\dfrac{8}{42}} \times 100$

$\mathrm{ \% \: error = \dfrac{800}{42} }$

$\mathrm{ \% \: error = 19.04 \%}$

In kite PQRS , TQ=3 cm and TP=4 cm. What is SP ? Enter your answer in the box.

yawa3891 [41]

Answer:

Kite is a quadrilateral in which two disjoint pairs of consecutive sides are congruent

Given: In kite PQRS

where PR and SQ are the diagonals of Kite respectively as shown in the figure given below.

Given: TQ = 3 cm and TP = 4 cm

Let PR is the main diagonal and SQ is the cross diagonal of kite PQRS as shown in figure, also let T is the intersection point of PQRS.

By Property of Kite, diagonal SQ bisects PR at perpendicular angle i.e, 90 degree.

i,e

Then, in right angle ΔQTP

$PQ = \sqrt{TQ^2+TP^2}$ [Using Pythagoras theorem]

Substitute the given values of TQ and TP we have;

$PQ = \sqrt{3^2+4^2} =\sqrt{9+16} =\sqrt{25} = 5 cm$

Also, PQ = SP [by definition of kite]

therefore, the side SP = 5 cm.

3.9 times 10 to the seventh power

ra1l [238]

Hey there!

3.9 times 10 to the seventh power is equivalent to the equation 3.9 × $10^{7}$

The seventh power indicates the amount of times the decimal moves to the right of 3.9, so that expression would be equivalent to 39,000,000.

Hope this helps!
